1. Introduction This manual is designed to guide you in the use and care of the Orion TI-34 Talking Scientific Calculator. The Orion TI-34 is a specially designed unit, based on the popular TI-34 scientific calculator. The functionality and operation of the Orion are identical in all respects to the standard TI-34. The only difference is that additional controls and options are provided to adjust the speech output to your preference. We will first start by familiarizing you with the speech controls on the unit and then describe the math functions. You may also refer to the TI-34 teacher's guide.
Your Orion TI-34 comes with a host of advanced but user-friendly features:
This manual references various functions of the calculator in the following manner: Key names are enclosed in square brackets. If a function is invoked by multiple keystrokes as is the case for secondary functions of keys, it is enclosed in square brackets and the individual keys that are required to be pressed are all enclosed in round brackets. The position of the key is enclosed in round brackets. e.g.
(Row 1, Column 2)
[0] The digit zero, this is the primary function of this key.
[FD] ([2nd][0]) Floating Decimal, this is the secondary function of the [0] key and is invoked by pressing the [2nd] and [0] keys.
Speech output is denoted by enclosing it in quotes e.g. "All Clear".
2. Getting Familiar with your ORION TI-34 Calculator
You should have received the following items in your Calculator package:
This section will familiarize you with the location and functions of the primary controls of your Orion TI-34 Talking Scientific Calculator.
First, place the unit on a desk or hold it in your hand such that the keypad is on top and facing you. In this position, you should be able to feel the speaker grill and four rubber feet on the bottom of the unit. Orient the unit so that the keys are located on the lower end of the unit (towards you) while the flat LCD display is at the upper end (away from you). This is the normal operating orientation for the unit.
With the unit in this position, on the left side of the unit, you will find the volume control thumb-wheel towards the top and the earphone socket towards the middle.
On the right hand side of the unit, towards the top you will find the power socket for inserting the battery charger (AC adapter) plug. Towards the middle of the right-hand side, you will find two push- button switches. The upper button, called the LEARN/MODE button, is for entering learning- mode and to select various speech options. The lower button, called the REPEAT/OFF button, repeats the number on the display and turns the power off when pressed for more than 2 seconds.
Your Orion TI-34 calculator has a built-in re- chargeable battery pack, which gives you freedom of carrying the calculator and working anywhere and also relieves you from having to replace the batteries frequently.
It can also be powered by the AC adapter provided with the unit, which can be plugged into a standard 110V wall socket. The AC adapter also serves to charge the battery.
CAUTION
Do NOT use any other AC adapter with the Orion TI-34. This can result in damage and destruction of the unit and will render the warranty void. The accessories (AC adapter/charger and earphone) supplied with the Orion TI-34 have been specially designed for use with the unit. Using the unit with any accessories other than the ones supplied by Orbit Research may result in serious damage or even destruction of the unit. Orbit Research will not be responsible for any direct or consequential damage or injury resulting from the use of such accessories.
Low battery Indication:
The unit continuously monitors the battery. When it detects a low power level, the unit will speak "Low Battery". Thereafter the unit gives beeps at regular intervals to remind you to insert the AC adapter for charging the battery. If you fail to do so the unit gives a final warning message "Low Battery Power Off" and shuts down. Under these circumstances, any data in memory or display will be lost.
Charging:
When you hear the "Low battery" warning, it is an indication that the batteries have become weak and need to be recharged. Plug in the battery charger (AC adapter) provided with the unit into the power- socket near the top on the right hand side of the unit. The charger can also be plugged in at any time; it will serve to top up the charge on the batteries. Ensure that the adapter is plugged into a live wall- socket when plugged into the power-jack of the unit. Note that you can continue to use your Orion TI-34 calculator while it is being charged by the battery charger.
Please note that the batteries should be charged for at least 16 hours before using the unit for the first time.
The calculator will operate for several hours or days depending on the extent of use. The life of the battery is approximately 7 hours of continuous use. It is not necessary to change the batteries inside the unit until they have completed at least 500 charge and discharge cycles. At this point they may become "tired", resulting in a decrease in the duration of use before they need to be recharged.
The batteries in the unit CANNOT be replaced by the user. Please contact Orbit Research for battery replacement.
To switch ON the Orion TI-34 Talking Scientific Calculator press the AC/ON key which is at the top- right corner of the keypad. Make sure that the volume control (described in the next section) is not at the minimum volume setting, since you will not be able to hear speech in that case. When you switch on the unit by pressing the AC/ON key you will hear the unit first give a beep and then say "Power On" on releasing the key. If you do not hear this, please charge the unit for some time and try again. To switch the unit off, press and hold the REPEAT/OFF button (the lower of the two buttons on the right hand side of the unit) for 2 seconds or more.
The volume can be controlled by the volume control thumb-wheel on the left side of the unit. It is easier to set the volume when the unit is on since you can listen to the change. Rotate the volume control thumb-wheel counter-clockwise (with a downward motion) to increase the volume level and clockwise (with an upward motion) to decrease the volume. A high quality earphone is provided with your calculator. To use the earphone, plug the jack into the earphone socket located on the left side of the unit, just below the volume control. Plugging in the earphone disconnects the internal speaker and all speech is heard through the earphone to enable comfortable private use.
The Orion TI-34 is equipped with a special Learning-Mode designed to help you locate keys and confirm their functionality at any time, even in the middle of a calculation. You can enter Learning- Mode at any time by pressing the LEARN/MODE button (the upper button on the right hand side of the unit) very briefly (less than 1.5 seconds). When the unit is in learning-mode the previous state of the calculator remains preserved, i.e. if you were in the middle of an operation, it is not interrupted and the display remains unchanged.
In learning-mode, every key that is pressed is spoken out to help you locate a particular key if you do not know its position. Each key pressed by itself speaks out its primary function, and when pressed in combination with various modifying keys, it speaks the secondary functions as set by the modifying key (this will become clearer in the following sections). When you exit the learning-mode by briefly pressing the LEARN/MODE button again, the calculator returns to the speech and operational mode you were using before entering learning mode. It also restores all preferences in use before you entered learning- mode and you can resume operation from precisely the point where you had left it.
Note that when entering learning mode, the unit always reverts to the default Decimal Mode (which is the mode at power-up). If you need to locate key functions in other modes, you can easily enter those modes as described in the following sections.
The keys on the Orion TI-34 have a positive tactile feel and are designed to be sensitive for easy operation. Hence we recommend that while getting familiar with the unit, the user uses learning mode to locate the position of each key sequence listed in the next section.
The Orion TI-34 has 42 keys arranged in 9 rows and 5 columns. Some keys ([MODE], [2nd] and [=]) are larger and occupy more than one position. This section will describe the location of each of the keys. We will follow a (row, column) numbering scheme where the position of a key will be specified by its row and column with the bottom left corner key being in row 1 and column 1.
Each key can have several functions, determined by which mode the calculator is in and by the sequence of keys pressed.
When pressed by itself, each key performs its primary function depending on the calculator mode as described below. When pressed immediately after the [2nd] key (located in the 6th row and first and second columns, and wider and shorter than other keys for easy identification), each key performs its secondary function, again depending on the calculator mode. For example in the Decimal Mode, [1][SIN] calculates the sine of 1, while [1][2nd][SIN] calculates the arcsine of 1. In addition, the [HYP] key, when pressed before a trigonometric function key, generates the hyperbolic equivalent of the function. The [2nd] and [HYP] modifiers can be cancelled by pressing these keys again, upon which the unit speaks "Normal" after the key is spoken out.
The Orion TI-34 calculator can be used in five different modes viz. Decimal (the default mode at power-up), Hexadecimal, Octal, Binary and Statistical. These modes can be selected using the [MODE] key. The [MODE] key is located in the 6th row and 3rd and 4th columns. It is wider and shorter than the other keys for easy identification. The five modes can be set by pressing the [MODE] key followed by number keys as shown below.
Key Sequence
Calculator Mode
[Mode][1]
Decimal mode
[Mode][2]
Binary mode
[Mode][3]
Octal mode
[Mode][4]
Hexadecimal mode

Pressing any other key than the ones mentioned above after pressing mode key, automatically deactivates the mode function. Unlike the [2nd] and [HYP] modifiers, the mode function does not get deactivated when pressed twice consecutively.
Note: Some operating features such as trigonometric functions are available only in decimal mode and statistics mode.
Given below are the positions of the keys on the keypad (in row, column format), the functions that the key performs and the sequence of keys required to invoke the function. If a key has a special function in a particular mode other than the default Decimal Mode, e.g. the [4] key gives the mean in Statistics Mode, the mode is shown in round brackets.

The following key sequences can be used to change the format of the display of your answers.
1. [FD] ([2nd][0]), This key sequence selects the floating decimal notation; it does not cancel the fix decimal setting. Results are displayed and spoken in the following range: -9999999999 to - 0.000000001, 0, 0.000000001 to 9999999999. If the result is outside this range it is displayed and spoken out in scientific notation.
2. [SCI] ([2nd][.]), This key sequence selects the scientific notation. Each result is expressed and spoken as a mantissa and an exponent.
3. [ENG] ([2nd][+/-]), This key sequence selects the engineering notation. This is like scientific notation, except that all exponent values are multiples of three.
4. [EXP], This key allows you to enter an exponent in scientific or engineering notation. You can enter a number as small as +/-1 x 10^99 and as large as +/-9.999999999 x 10^99. To enter such a number.
a. Enter the Mantissa. If it is negative, press the [+/-] key.
b. Press [EXP]. The unit will say the mantissa with a zero exponent if you press the repeat button at this point. If you have pressed the [EXP] without first entering a mantissa, the calculator restores the mantissa to 1 by default.
c. Enter the exponent. Press the [+/-] key if it is negative. If an incorrect key has been pressed, then you can simply re-enter the correct digits - the last two digits you enter are displayed and used for calculations.
d. Press [=] to enter the number. This is not essential and the number will be accepted even if any other operational key is pressed. Then if necessary, press [SCI] ([2nd][.]) or [ENG] ([2nd][+/-]) to set the display and speech in the desired format.
5. [FIX] ([2nd][Backspace], Fixed Decimal key sequence. This key sequence enables you to set the number of decimal places displayed and spoken in a result.
a. To fix the number of decimal places, press [2nd][Backspace] and then press the appropriate digit key (0-9). This will result in the updated display being spoken to confirm the decimal places selected.
b. To undo the fixed-decimal setting, press [2nd][Backspace][.]
If a result has more than the selected number of decimal places, the displayed result is rounded. If a result has less than the selected number of decimal places, trailing zeroes are inserted.
You can transform the result of a calculation from one format to another. To convert a result simply press the [2nd][Backspace], [2nd][.], [2nd][+/-] or the [2nd][0] key sequence, depending on the display format desired.
Enter the number. Press [=]. Then press one of the key sequences described above.
For clearing incorrect entries and correcting them you can use either the [CE/C], [AC/ON] key or the [Backspace] key.
[CE/C] This key has the following uses:
1. To clear an incorrect numerical entry, press [CE/C] once.
2. To clear an error condition, indicated by E in the display and spoken as "Error", press [CE/C] once.
3. To clear the display and all pending operations, press [CE/C] twice.
By pressing the [AC/ON] key you can reset the calculator entirely.
The [backspace] key deletes the last digit you entered. Pressing it repeatedly allows you to correct as many digits as you wish. The display is spoken each time you press the [backspace] key if numerical keys or the [EXP], [(], [)], [MODE], [HYP], [DRG], [ab/c], [.], [+/-] or [FIX] key preceded the [backspace] key. Pressing the [backspace] key twice also causes the unit to speak out the display.
[x exchange y] ([2nd][RCL]): X exchange Y key sequence. This key sequence exchanges:
1. The values of x and y in universal power and root calculations.
2. The minuend and the subtrahend in subtraction.
3. The divisor and dividend in division.
4. The constant value and the value in the display in a constant calculation.
Pressing the REPEAT/OFF key briefly at any time will cause the contents of the display to be spoken.
Your Orion TI-34 Talking Scientific Calculator comes with a host of features that enable you to adjust the speech to your liking. There are three major speech modes and three feature modes.
Press the SPEECH/MODE button, the top button on the right side of the unit, for more than two seconds until you hear "Enter speech mode menu". This indicates that the unit has entered the Speech Mode Menu, which will allow you to select/cancel various speech and feature modes. These modes are selected/cancelled by pressing digit keys while in the Speech Mode Menu, as described in the following sections.
To exit the speech mode menu, press the speech mode button again briefly. You will hear "Exit speech mode". The calculator remembers the selection(s) made by you and returns to the calculations you were performing when you first entered the speech selection mode. You may now continue normal use of the calculator.
In this speech mode the key that is pressed is spoken followed by the contents of the screen. For example: If you entered [4][5], the unit will say "four", "five", "beep" (a beep indicates that the display is being spoken out), "four", "five" (which are the contents of the display).
Press the digit [1] when you are in the speech mode menu to select this speech mode and the unit will confirm by speaking "Verbose Mode".
There are certain keys in your Orion TI-34 calculator that deliver the answer immediately after they have been pressed. These "Active keys" are for instance, the [SIN], [X2], and [LOG] keys. In the "Answer Mode", the unit speaks out the answer as soon as an active key is pressed, after announcing the key-press. Pressing an "Inactive key" such as a digit key does not cause the display to be spoken out.
For example: If you have entered [0][COS], the unit will say "zero", "cosine", "beep" (meaning that display is being spoken out), "one" (which is the answer to cos(0)).
Press [2] when you are in speech mode menu to select this speech mode and the unit will confirm by speaking "Answer Mode". Then exit the speech mode menu by pressing LEARN/MODE button briefly for the selection to get activated.
In this speech mode the key pressed is always spoken but the answer is spoken only when you press the [=] ("equals") key. However, answers to some operations which are not spoken on pressing the equals key are spoken in this mode. These are: The outcome of pressing the [R to P], [P to R] and [x exchange y] keys, decimal equivalent of an improper fraction and the change in display due to the FIX key.
For example: If you have entered [0][COS], the unit will say "zero", "cosine". Only on pressing the [=] key, you will hear "equals" "one" (which is the answer to cos(0)). Of course, the repeat button may be used at any time to vocalize the display. Press [3] when you are in speech mode menu to select this speech mode and the unit will confirm by speaking "Quiet Mode". Apart from these basic speech modes the Orion TI- 34 has additional feature modes which can be used with all speech modes.
Pressing the [4] key once in the speech mode menu invokes this mode and causes the unit to say "Descriptive Mode". In this feature mode the speech is spoken in a descriptive fashion. For example: 123 on the display will be spoken out as "one hundred twenty three".
Pressing the [4] key again cancels this feature and you will hear the unit speak "Simple Mode".
Pressing the [5] key once in the speech mode menu invokes this mode and causes the unit to say "Speak Special Functions". In this feature mode you can hear the special indicators like 2nd, HYP, DEG, RAD etc. along with the answer each time the calculator speaks out the display. Pressing the [5] key again cancels this feature mode and you will hear the unit speak "Special Symbols not Spoken".
Pressing the [8] key once in the speech mode menu invokes this mode and causes the unit to say "NOT Flush Speech". This indicates that "Buffered Speech Mode" has been turned on. In this mode, if the user presses any key while some other key or display is being spoken out, the new key-press (and resulting answer) will be spoken out after the ongoing speech is completed. Pressing the [8] key once again turns off the Buffered Speech Mode and any new key- press is immediately spoken out, flushing the ongoing speech. The unit confirms this mode by speaking "Flush Speech".
When you first switch it on, the Orion TI-34 operates in Answer Mode with the following Feature Modes: Simple Mode (non-descriptive), Special Symbols Not Spoken, Flush Speech. You can return to these default settings by pressing the [6] key when in the Speech Mode Menu.
If you do not operate the unit for a period of time, it automatically switches off after a pre-selected time period to conserve battery life. You can select this time period (called "Power-Off Time"), to suit your preference. The power-off times available are one, three and ten minutes.
To select power-off time, enter speech mode menu. Press the [7] key; you will hear the unit speak "Automatic Power-Off Time Setting one minute" which means that the present setting is such that if the calculator is left unattended for one minute it will shut down. Pressing the key [7] again will cycle the setting through three and ten minutes. Exit speech mode menu and the unit will remember the power off setting. Thirty seconds before the calculator shuts down it gives a "beep" to warn you that you may lose any data in the memory and display if the unit shuts down. You may prevent it from shutting down by pressing any key, including the REPEAT/OFF and LEARN/MODE buttons. The unit will give two "beeps" 15 seconds before final shut down as a final warning and after which it will speak "Automatic Power Off" and shut down. The default power off time is three minutes.
The [+], [-], [x], and [divide] keys perform the arithmetic operations of addition, subtraction, multiplication and division, respectively. The [=] key completes all pending operations and displays and speaks the result.
The [1/x], [x2], [square root] and [cube root] keys calculate the reciprocal, square, square root and the cube root of the displayed number, respectively. These are immediate functions (Active keys) that operate on the displayed number, and do not need a second operand.
The key sequence [%] ([2nd][=]) performs percentage calculations.
The keys [0] through [9] and [A] through [F] are used to enter digits in the display. ([A] through [F] are available only in the hexadecimal mode.) You can enter a maximum of 10 digits and a decimal point. If you attempt to enter more than 10 digits, the unit will sound a warning tone and the digit will be ignored.
The [.] key enters a decimal point in a numeric value.
The [+/-] key changes the sign of the number in the display. To enter a negative number, first enter the number as a positive value, then press [+/-]. If the display shows only zero then on pressing the [+/-] key the unit will speak out "PLUS". In binary, hexadecimal or octal mode, the [+/-] key works as the [NEG] key and calculates the two's complement of the number in the display.
The [backspace] key clears the last digit of the current numeric entry. Repeatedly pressing this key clears an entry digit-by-digit until the display becomes zero.
The [(], [)] keys open and close a parenthetical expression, respectively. A set of operations enclosed in parentheses is given priority over operations outside the parentheses. You can enter a maximum of 6 sets of parentheses.
[Pi] ([2nd][EXP]). This key sequence enters the value of Pi in the display.
The [SIN], [COS], and [TAN] keys calculate the sine, cosine and tangent, respectively, of the angle in the display.
The calculator interprets the angle in the units (Degrees, Radians or Grads) selected by the [DRG] or [DRG To] ([2nd][DRG]) key sequence. If you enter an angle in degree/minute/second format, you must first convert it to decimal degrees before using these functions.
Inverse trigonometric functions:
The [SIN-1] ([2nd][SIN]), [COS-1] ([2nd][COS]), and [TAN-1] ([2nd][TAN]) key sequences calculate the angle (in the selected units) whose sine, cosine or tangent is in the display. [To DD] converts an angle from degrees/minutes/seconds format to decimal degrees. Enter the angle as D.MMSSs and press
[To DD]. Here D represents degrees (0-7 digits), the dot is the decimal point, MM represents minutes (must be 2 digits), SS represents seconds (must be 2 digits) and s is the fractional part of a second
The [To DMS] ([2nd][To DD]) key sequence temporarily displays and speaks the current value in degrees/minutes/seconds. Enter the angle as D.ddddddd and press [To DMS] ([2nd][To DD]).
The [DRG] key cycles the angle-unit setting between degrees, radians and grads without affecting the displayed or spoken angle.
The [DRG To] ([2nd][DRG]) cycles the angle setting between degrees, radians and grads for display, entry and calculation. It also converts the value shown on the display to the new unit selected by the [DRG To] key.
The calculator is automatically reset to degree angle units when you press the [AC/ON] key.
The [HYP] key, when pressed before a trigonometric function key, enables you to use the trigonometric function keys to access hyperbolic functions. Similarly, the [HYP][2nd] key sequence enables you to perform inverse hyperbolic functions, when pressed before a trigonometric function key.
The [Y power X] (universal power) key raises any positive number to any power (within range of the calculator). The key sequence [Y root x] ([2nd][Y power X]) (universal root) calculates any root of any positive number (within range of the calculator).
The [LN] key calculates the natural logarithm (base e) of the number in the display. The [ex] ([2nd][LN]) key sequence calculates the natural antilogarithm of the number in the display.
The [LOG] key calculates the common logarithm (base 10) of the number in the display. The [10x] ([2nd][LOG]) key sequence calculates the common antilogarithm of the number in the display.
The [STO] key stores the displayed number in memory, replacing the previous memory contents. To clear the memory, press [STO] when "0" is displayed.
The [RCL] key displays and speaks (recalls) the number stored in memory, without affecting the memory contents.
The [2nd][STO] key sequence exchanges the number on the display with the number in the memory.
The [SUM] key adds the number on the display to the number in the memory.
The [x!] ([2nd][SUM]) key calculates the factorial of the displayed value which must be an integer in the range of 0 to 69.
To enter statistical data values:
1. Press [MODE][1][MODE][5] to clear the statistical registers and enter the statistical mode.
2. Enter a data value and press the [Sigma +] key. Continue until all the data values are entered. If you enter an incorrect value, remove it by re- entering the value and pressing [Sigma -] ([2nd][Sigma +]) then enter the correct value and press [Sigma +] . Each time you press the [Sigma +] or the [Sigma -] ([2nd][Sigma +]) keys, the display shows the number of data values currently in the registers. You will be able to hear this if you are in verbose or default speech modes.
Note: The [Sigma +] and [Sigma -] keys will be spoken out only in Statistics Mode. In other modes these keys will generate a warning tone and will be ignored.
After entering the data values, statistical operations can be performed as shown below:
[mean] ([2nd][4]) mean of the entered data
[Standard Deviation] ([2nd][6]) population standard deviation (n weighting)
[Standard Deviation n-1] ([2nd][5]) sample standard deviation (n-1 weighting)
[Sigma x] ([2nd][1]) sum of data values
[Sigma x^2] ([2nd][2]) sum of squares
[n] ([2nd][3]) number of data values
[CE/C] clears the current entry . Does not affect statistical data or memory.
[AC/ON] Clears all statistical data, STAT mode and memory.
(such as 1/6) as a/b:
1. Enter as many as six digits for a.
2. Press [ab/c]. The unit will say "over" between the values entered for a and b if the repeat button is pressed to speak out the display.
3. Enter as many as three digits for b.
Note: If you attempt to enter more than 3 digits for b, the unit will sound a warning tone and ignore the entry.
If you enter an improper fraction the calculator changes it to a proper fraction when you press an operation key.
To enter a mixed fraction as a b/c:
1. Enter as many as three digits for a.
2. Press [ab/c]. The unit will say "over" between the values entered for a and b if the repeat button is pressed.
3. Enter as many as three digits for b. Note: If you attempt to enter more than 3 digits for b the unit will sound a warning tone and ignore the entry.
4. Press [ab/c]. The unit will say "and" between the values entered for a and b and "over" between the values entered for b and c if the repeat button is pressed.
5. Enter as many as three digits for c. Note: If you attempt to enter more than 3 digits for b the unit will sound a warning tone and ignore the entry.
Converting fractions:
To convert a mixed, proper fraction to an improper fraction, press [d/c] ([2nd] [ab/c]) To convert a fraction to a decimal value, press [=][ab/c]. The decimal equivalent of the fraction will be displayed and spoken out. Press [ab/c] again to change the result back to a fraction.
To convert from polar to rectangular:
1. Select the desired angle units.
2. Enter the r-coordinate and press [x exchange y] ([2nd][RCL])
3. Enter the theta-coordinate.
4. Press [P to R] ([2nd][R to P]) to convert the coordinates and display the x-coordinate.
5. Press [x exchange y] ([2nd][RCL]) to display the y- coordinate.
To convert from rectangular to polar follow the same steps as given above except that in step 2 and 3 enter the x and y coordinate respectively. Press the [R to P] key in step 4.
Note: To recall the x or the r-coordinate, press [x exchange y] ([2nd][RCL]) again. You can use [x exchange y] ([2nd][RCL]) to alternately display the x and the y-coordinates until you press [CE/C][CE/C], [AC/ON], or [=] or use [MODE] to change the mode. The unit always speaks out the display when the x-coordinate or the y- coordinate is displayed.
The [MODE][1] key sequence selects the decimal mode. When you press the above sequence the number in the display is automatically converted to its decimal equivalent.
Note: Normally, you should keep the calculator in the decimal mode. Some of the calculator's operating features are limited in other modes.
The [MODE][2] key sequence selects the binary mode and shows the BIN indicator on the display (which is spoken out when the Special Functions feature mode is active). In this mode, you can only perform arithmetic operations with binary numbers (integers only).
When you press the key sequence above, the integer portion of the number in the display is automatically converted to its binary equivalent and is spoken out. You can enter positive binary numbers as large as 111111111 (9 digits). Numbers beyond this are interpreted as negative (two's complement) numbers. All keys that are not functional in this mode sound a warning tone.
The [MODE][3] key sequence selects the octal mode and shows the OCT indicator on the display (which is spoken out when the Special Functions feature mode is active). In this mode, you can perform arithmetic operations with octal numbers (integers only).
When you press the key sequence above, the integer portion of the number in the display is automatically converted to its octal equivalent and spoken out. You can enter positive octal numbers as large as 377777777 (9 digits). Numbers beyond this are interpreted as negative (two's complement) numbers. All keys that are not functional in this mode sound a warning tone.
The [MODE][4] key sequence selects the Hexadecimal mode and shows the HEX indicator on the display (which is spoken out when the Special Functions feature mode is active). In this mode, you can perform arithmetic operations with hexadecimal numbers (integers only).
When you press the key sequence above the integer portion of the number in the display is automatically converted to its hexadecimal equivalent and spoken out. You can enter positive hexadecimal numbers as large as 2540BE3FF (9 digits). Numbers beyond this are interpreted as negative (two's complement) numbers. All keys that are not functional in this mode sound a warning tone. To enter the hexadecimal digits A through F, use the following
keys: [SIN] for [A]
[COS] for [B]
[TAN] for [C]
[1/x] for [D]
[R to P] for [E]
[To DD] for [F]
