2015/22/7

## Introduction

The Orion TI-30XS is based on the popular TI-30XS MultiView™ Scientific Calculator made by Texas Instruments Incorporated. It is specially modified for accessibility for users with visual impairment. The functionality and operation of the Orion TI-30XS are identical in all respects to the standard TI-30XS Calculator. The only differences are additional controls, jacks, speakers, and software for accessible feedback of the calculator's output and the user's input.

This guide is designed to instruct you in the use and care of the Orion TI-30XS. It is accurate and complete as of the date of its publication. For the latest version, see http://tech.aph.org/xs_info.htm

The Orion TI-30XS information page contains the Quick Start guide and information about updates.

In addition to the User's Guide, there is an e-mail list th at discusses the Orion TI-30XS. To subscribe, send an e-mail to xs-subscribe@tech.aph.org. APH customer support and developers and interested, knowledgeable users exchange information here. The e-mail list is a great place to get usage tips, ask questions, or make suggestions.

For the purposes of this guide, the standard TI-30XS MultiView™ Scientific Calculator from Texas Instruments Incorporated is referred to as the TI-30XS. The Orion TI-30XS MultiView™ Talking Scientific Calculator is referred to as the Orion TI-30XS.

In order to make this document accessible for all users, we indicate keys on the TI-30XS portion of the calculator with a bold font. For visual and audio clarification purposes, we also use brackets around the words or symbols for a particular keys, 2nd functions, or menu items when necessary. For example, the key marked "sto right arrow" (store) is designated as [sto right arrow] and the 2nd function marked "right arrow %" is designated as [right arrow %]. Everything within the brackets is one key press.

If using the NVDA screen reader, it is recommended that you change the default setting from "read some punctuation" to "read most punctuation" for the best listening comprehension of this guide.

### Orientation and Functions

This section helps you become familiar with the location and various functions of your Orion TI-30XS.

To begin the exploration process, position the Orion TI-30XS so that the keys face up and the ports are at the top, as shown below.

This is the normal operating position. When holding the calculator or if it is lying on a flat surface with the keys facing up, the ports at the top of the calculator are the earphone jack on the left and the USB Micro-B port on the right. (In the picture below the ports look reversed because they are facing you instead of away from you.)

Above the screen on the face of the Calculator are three keys in a horizontal region. The label on the keys from left to right are A, S/L, and ↺R which stand for Access, Silence/Learn, and Repeat. These three keys are the Orion Access keys (shown below).

The keys on the bottom half of the calculator are the TI-30XS keys (shown below). There are 41 keys laid out in five rows and nine columns and a four-key directional pad in the top-right corner. The four keys of the directional pad are the arrow keys for the TI-30XS. The power on key is in the bottom-left corner, diagonally opposite from the directional pad. It has a raised outline on the bottom-left corner of the key.

The screen (shown below) is the rectangular, flat section between the Orion Access keys (on the top) and the TI-30XS keys (on the bottom).

### Power Supply and Charging

The Orion TI-30XS comes with a built in user-replaceable chargeable battery. It is imperative that this calculator be fully charged prior to first-time use. The chargeable battery in the Orion TI-30XS lasts several days, depending on usage. Always charge the unit before any important test or assignment.

Follow these steps to charge the device:

1. Hold the calculator in its operating position so that the keys are face up and the access keys are the farthest away from you.
2. Plug the Micro-B end of the USB cable into the Micro-B port on the side farthest away from you. The Micro-B end of the cable goes into the port with the pins down.
3. Plug the standard A male end of the USB cable into the USB wall adapter.
4. Plug the wall adapter into the wall socket.

Note: Fully charge the battery prior to first-time use of the calculator. This should take about 4 hours. You can use the Orion TI-30XS while it is charging.

### Operation Procedure

Follow these steps to turn the calculator on and off:

1. To turn the device on, press the on key located at the lower left-hand corner of the calculator positioned in column 1, row 1.
2. To turn the device off, first press the 2nd key located in column 1, row 9, and then the on key.

The display is cleared, but the history, settings, and memory are retained.

Note: The Automatic Power Down™ (APD™) feature turns off the TI-30XS calculator automatically if no key is pressed for about 5 minutes. Press on after APD. The display, pending operations, settings, and memory are retained. If you were using the Learn mode, the calculator returns to the location and procedure prior to the initiation of Learn mode.

## Orion TI-30XS Operations

### Accessibility Functions

The Orion TI-30XS has three keys at the top of the unit and above the screen that control the accessibility features. This region is what is known as the Orion accessory which was added to the original TI-30XS to make it accessible for individuals with visually impairment.

The keys are (from left to right) Access, Silence/Learn , and Repeat.

Each of the Orion Access keys has multiple functions depending on how they are pressed, tapped, long pressed, or used in combination with the Access key. The following sections explain the use of the three Orion Access keys.

#### Access Key (A)

• Tap the Orion A key followed by an Access Mode key to get the modified functionality for that particular key. For example Access followed by Repeat activates the spell mode.
• Holding the A key with a long press enters Orion settings which allows you to change settings such as speed and/or volume. Pressing and holding the A key again turns off Orion settings. Pressing a non-Orion settings key also exits the Orion settings. See Orion Settings for more accessibility information.

#### Silence/Learn Key (S/L)

• Tapping the S/L key silences whatever is currently being spoken.
• Pressing the A key followed by the S/L key turns off access functionality until one of the Orion Access keys is pressed or the calculator is turned off and on again. This is a good mode to use when an instructor would like to use the calculator without speech.
• Holding this key with a long press switches the calculator to Learn mode.

#### Repeat Key (↺R)

• Tapping the ↺R key repeats the last spoken text.
• Pressing the A key followed by the ↺R key spells out the last spoken text.
• Press and hold the ↺R key to read the entire screen.

#### Learn Mode

The Orion TI-30XS is equipped with a Learn mode designed to assist you with locating keys and confirming their functionality. Learn mode can be used at any time. When the unit is in Learn mode, the calculator retains its previous status. For example, if you are in the middle of an operation and enter the Learn mode, the calculator operation is not interrupted and the display remains unchanged.

To enter Learn mode, press and hold the middle Orion Access key (S/L) located at the top of the calculator and above the screen.

In Learn mode, to assist you with locating a particular key, each key and its primary function is announced when pressed. When used in combination with the 2nd key, the Orion TI-30XS announces the secondary function for the pressed key.

To exit Learn mode, press and hold the middle Orion Access key (S/L). The calculator returns to the speech and operational mode at precisely the same point you were at prior to entering Learn mode, and it restores all the previously set preferences.

#### Orion Settings

To enter Orion Settings press and hold the Access key until Orion setting on is announced. When in Orion Settings the following keys and functions are available:

 Up Arrow Volume up Down Arrow Volume down Right Arrow Rate up Left Arrow Rate down 0 Announce ticks on table screen (toggles on and off)

#### Access Mode Keys

To enter Access Mode tap the Access key. When in Access mode the following functionality is available.

### Home Screen

On the Home screen, you can enter mathematical expressions and functions, along with other instructions. The answers are displayed on the Home screen. The TI-30XS screen can display a maximum of four lines with up to 16 characters per line. For entries and expressions of more than 16 characters, you can scroll left and right by pressing the right arrow or left arrow on the directional pad to view the entire entry or expression. Similarly, to view entries and expressions that are more than four lines, you can scroll up and down by pressing the up and down arrows on the directional pad.

The Orion TI-30XS has the ability to display math in both Classic and MathPrint™ mode. Classic mode displays input and output on a single line on screen and is fully accessible. Due to the difficulty in accessing information not on the screen, MathPrint mode is not accessible. When the Orion accessibility is muted, MathPrint mode still works and can be used by visual users of the calculator. If the MathPrint mode is active, a message is announced indicating that MathPrint is not supported and instruction is given to change to Classic mode. (See the Modes section to learn how to switch to Classic mode.)

It is not necessary to use MathPrint mode to use the full functionality of the TI-30XS. If you want to know more about MathPrint mode, see the TI-30XS Scientific Calculator documentation from Texas Instruments Incorporated.

When you calculate an entry on the Home screen, depending upon space, the answer is displayed either directly to the right of the entry or on the right side of the next line.

Special indicators may display on the screen to provide additional information concerning functions or results. These are spoken when needed.

### 2nd functions

2nd

Most keys can perform two functions. The primary function is indicated on the key and the secondary function is displayed above it. Press 2nd to activate the secondary function of a given key. Notice that 2nd appears as an indicator on the screen. To cancel it before entering data, press 2nd again. For example, 2nd [√] 25 enter calculates the square root of 25 and returns the result, 5.

### Modes

mode

Use mode to choose modes. Press down arrow, up arrow, left arrow, or right arrow to choose a mode, and enter to select it. Press clear or 2nd [quit] to return to the Home screen and perform your work using the chosen mode settings.

Default mode settings are shown highlighted (DEG, NORM, FLOAT, MATHPRINT).

NORM  SCI  ENG Sets the numeric notation mode. Numeric notation modes affect only the display of results, and not the accuracy of the values stored in the unit, which remain maximal.

NORM displays results with digits to the left and right of the decimal, as in 123456.78.

SCI expresses numbers with one digit to the left of the decimal and the appropriate power of 10, as in 1.2345678∗10⁵ (which is the same as 123456.78).

Note: In some restricted environments (for example function table, data editor, and the 2nd [recall] menu), the TI-30XS calculator may display E instead of ∗10ⁿ.

ENG displays results as a number from 1 to 999 times 10 to an integer power. The integer power is always a multiple of 3.

Note: ×10ⁿ is a shortcut key to enter a number in scientific notation format. The result displays in the numeric notation format set in mode.

FLOAT  0123456789 Sets the decimal notation mode.

FLOAT (floating decimal point) displays up to 10 digits, plus the sign and decimal.

0123456789 (fixed decimal point) specifies the number of digits (0 through 9) to display to the right of the decimal.

CLASSIC  MATHPRINT™

CLASSIC mode displays inputs and outputs in a single line.

MathPrint mode displays most inputs and outputs in textbook format.

Note: The Orion TI-30XS has the ability to display math in both Classic and MathPrint™ mode. Classic mode displays input and output on a single line on screen and is fully accessible. Due to the difficulty in accessing information not on the screen, MathPrint mode is not accessible. When the Orion accessibility is muted, MathPrint mode still works and can be used by visual users of the calculator. If the MathPrint mode is active, a message is announced indicating that MathPrint is not supported and instruction is given to change to Classic mode.

Certain keys display menus: prb, 2nd [angle], data, 2nd [stat], 2nd [reset], 2nd [recall], and 2nd [clear var]. Some keys may display more than one menu.

Press right arrow and down arrow to scroll and select a menu item, or press the corresponding number next to the menu item. To return to the previous screen without selecting the item, press clear. To exit a menu or application and return to the Home screen, press 2nd [quit].

Press left arrow or right arrow to place the cursor horizontally over the expression entered. Press 2nd, left arrow or 2nd, right arrow to move the cursor directly to the beginning or end of the expression.

After an expression is evaluated, use up arrow and down arrow to scroll through previous entries, which are stored in the TI-30XS calculator's memory. You can reuse a previous entry by pressing enter to paste it on the bottom line, and then evaluating a new expression.

##### Example
 5, +, 4, enter Result = 9 up arrow Result = 9 up arrow Result = 5 + 4 enter Result = 5 + 4

[left-right arrow]

Press the [left-right arrow] key to toggle the display result between fraction and decimal answers, exact square root and decimal, and exact pi and decimal.

2nd [ans]

The most recently calculated result is stored to the variable Ans. Ans is retained in memory, even after the TI-30XS calculator is turned off. To recall the value of Ans:

• Press 2nd [ans] (Ans displays on the screen), or
• Press any operations key (+, -, and so forth) as the first part of an entry. Ans and the operator are both displayed.

### Order of operations

The TI-30XS calculator uses Equation Operating System (EOS™) to evaluate expressions. Within a priority level, EOS evaluates functions from left to right and in the following order.

 1st Expressions inside parentheses 2nd Functions that need a ) and precede the argument, such as sin, log, and all [R left-right arrow P] menu items 3rd Fractions 4th Functions that are entered after the argument, such as x² and angle unit modifiers 5th Exponentiation (^) and roots (x√). Note: In Classic mode, exponentiation is evaluated from left to right. The expression 2^3^2 is evaluated as (2^3)^2, with a result of 64. 6th Negation (-) 7th Permutations (nPr) and combinations (nCr) 8th Multiplication, implied multiplication, division 9th Addition and subtraction 10th Conversions ([n/d left-right arrow U n/d], [F left-right arrow D], [right arrow DMS]) 11th enter completes all operations and closes all open parentheses

### Clearing and correcting

 clear Clears an error message. Clears characters on entry line. Moves the cursor to last entry in history once display is clear. Backs up one screen in applications. delete Deletes the character at the cursor. 2nd [insert] Inserts a character at the cursor. 2nd [clear var] Clears variables x, y, z, t, a, b, and c. 2nd [reset] 2 or on & clear Resets the TI-30XS calculator. Returns unit to default settings; clears memory variables, pending operations, all entries in history, and statistical data; clears the constant feature, K, and Ans.

### Fractions

n/d   2nd [U n/d]   2nd [f left-right arrow d]   2nd [n/d left-right arrow U n/d]

In Classic mode, fractions with n/d do not allow operation keys, functions, or complex fractions in the numerator or denominator.

Note: In Classic mode, data editor, and table, use ÷ to perform complex division problems.

Calculations using fractions can display fraction or decimal results, depending on input.

The TI-30XS calculator defaults output to improper fractions. Results are automatically simplified.

• n/d enters a simple fraction. Pressing n/d before or after a number can result in different behavior. Entering a number before pressing n/d makes that number the numerator.
To enter fractions with operators or radicals, press n/d before you enter a number (in MathPrint mode only).
In Classic mode, press n/d between the entry of the numerator and the denominator.
• 2nd [U n/d] enters a mixed number. Press 2nd [U n/d] between the entry of the unit and the numerator.
• 2nd [n/d left-right arrow U n/d] converts between mixed numbers and simple fraction form.
• 2nd [f left-right arrow d] converts results between fractions and decimals.
##### Example
 n/d, U n/d 3, n/d, 4, +, 1, 2nd [U n/d], 7, n/d, 12, enter Result = 7/3 [n/d left-right arrow U n/d] 9, n/d, 2, 2nd, [n/d left-right arrow U n/d], enter Result = 4␣1/2 [F left-right arrow D] 4, 2nd, [U n/d], 1, n/d, 2, 2nd, [f left-right arrow d], enter Result = 4.5

### Percentages

2nd [%]      2nd [right arrow %]

To perform a calculation involving a percentage, press 2nd [%] after entering the value of the percentage.

To express a value as a percentage, press 2nd [right arrow %] after the value.

##### Example
 2, 2nd, [%], ×, 150, enter Result = 3 1, n/d, 5, right arrow, 2nd, [right arrow %], enter Result = 20%
##### Problem

A mining company extracts 5000 tons of ore with a concentration of metal of 3% and 7300 tons with a concentration of 2.3%. On the basis of these two extraction figures, what is the total quantity of metal obtained?

If one ton of metal is worth 280 dollars, what is the total value of the metal extracted?

 3, 2nd, [%], ×, 5000, enter Result = 150 +, 2, ·, 3, 2nd, [%], ×, 7300, enter Result = 317.9 ×, 280, enter Result = 89012

The two extractions represent a total of 317.9 tons of metal for a total value of 89012 dollars.

### x10n key

x10n

x10n is a shortcut key to enter a number in scientific notation format.

##### Example
 2, x10n, 5, enter Result = 200000 mode, down arrow, right arrow, enter Result = SCI clear, enter Result = 2 * 105

### Powers, roots and inverses

 x² Calculates the square of a value. The TI-30XS calculator evaluates expressions entered with x² and x-1 from left to right in both Classic and MathPrint modes. ^ Raises a value to the power indicated. If you insert an expression as the exponent, you must place it between parentheses. 2nd [√] Calculates the square root of a positive value. 2nd [x√] Calculates the nth root of any positive value and any odd integer root of a negative value. x-1 Gives the inverse of a value: 1/x. The TI-30XS calculator evaluates expressions entered with x² and x-1 from left to right in both Classic and MathPrint modes.
##### Examples
 5, ^, 2, right arrow, +, 4, ^, (, 2, +, 1, ), enter Result = 89 10, ^, (−), 2, enter Result = 1/100 2nd, [√], 49, enter Result = 7 2nd, [√], 3, ^, 2, right arrow, +, 4, enter Result = 5 6, 2nd, [x√], 64, enter Result = 2 2, x-1, enter Result = 1/2

### Pi

π

π = 3.141592653590 for calculations.

π = 3.141592654 for display.

##### Example
 π 2, ×, π, enter Result = 2π [left-right arrow] Result = 6.283185307
##### Problem

What is the area of a circle if the radius is 12 cm?

Reminder: A = πr².

 π, ×, 12, ^, 2, enter Result = 144π [left-right arrow] Result = 452.3893421

The area of the circle is 144 π square cm. The area of the circle is approximately 452.4 square cm when rounded to one decimal place.

2nd [angle]

2nd [angle] displays the choice of two submenus that enable you to specify the angle unit modifier as degrees (°), minutes ('), seconds ("); radian (r); gradian (g), or convert units using [right arrow DMS]. You can also convert between rectangular coordinate form (R) and polar coordinate form (P). (See Rectangular to Polar for more information.)

Choose an angle mode from the mode screen. You can choose from DEG (default), RAD, or GRAD. Entries are interpreted and results displayed according to the angle mode setting without needing to enter an angle unit modifier.

##### Examples
 RAD mode, right arrow, enter Result = RAD clear, sin, 3, 0, 2nd, [angle] Result = DMS 1: 1, ), enter Result = 1/2 DEG mode, enter Result = DEG clear, 2, π, 2nd, [angle], 4, enter Result = 360 [right arrow DMS] 1, ·, 5, 2nd, [angle], 6, enter Result = 1°30′0″
##### Problem

Two adjacent angles measure 12° 31′ 45″ and 26° 54′ 38″ respectively. Add the two angles and display the result in DMS format. Round the results to two decimal places.

 clear, mode, down arrow, down arrow, right arrow, right arrow, right arrow, enter Result = 2 clear, 12, 2nd, [angle] Result = DMS 1: 1, 31, 2nd, [angle], 2, 45, 2nd, [angle], 3, +, 26, 2nd, [angle], 1, 54, 2nd, [angle], 2, 38, 2nd, [angle], 3, enter Result = 39.44 2nd, [angle], 6, enter Result = 39°26′23″

The result is 39 degrees, 26 minutes and 23 seconds.

##### Problem

It is known that 30° = π/6 radians. In the default mode, degrees, find the sine of 30°. Then set the calculator to radian mode and calculate the sine of π/6 radians.

Note: Press clear to clear the screen between problems.

 clear, sin, 30, ), enter Result = 1/2 mode, right arrow, enter, clear, sin, π, n/d, 6, right arrow, ), enter Result = 1/2

Retain radian mode on the calculator and calculate the sine of 30°. Change the calculator to degree mode and find the sine of π/6 radians.

 sin, 30, 2nd, [angle], enter, ), enter Result = 1/2 mode, enter, clear, sin, π, n/d, 6, 2nd, [angle], 4, ), enter Result = 1/2

### Rectangular to polar

2nd [angle]

2nd [angle] displays a menu to convert rectangular coordinates (x,y) to polar coordinates (r, θ) or vice versa. Set Angle mode, as necessary, before starting calculations.

##### Example

Convert polar coordinates (r, θ)=(5, 30) into rectangular coordinates. Then convert rectangular coordinates (x, y) = (3, 4) into polar coordinates. Round the results to one decimal place.

 [R left-right arrow P] clear, mode, down arrow, down arrow, right arrow, right arrow, enter Result = 1 clear, 2nd, [angle], right arrow, 3, 5, 2nd, comma, 30, ), enter, 2nd, [angle], right arrow, 4, 5, 2nd, comma, 30, ), enter Result = 2.5 2nd, [angle], right arrow, 1, 3, 2nd, comma, 4, ), enter, 2nd, [angle], right arrow, 2, 3, 2nd, comma, 4, ), enter Result = 53.1

Converting (r, θ) = (5, 30) gives (x, y) = (4.3, 2.5) and (x, y) = (3, 4) gives (r, θ) = (5.0, 53.1).

### Trigonometry

sin cos tan    2nd [sin-1] [cos-1] [tan-1]

Enter trigonometric functions (sin, cos, tan, sin-1, cos-1, tan-1), just as you would write them. Set the desired Angle mode before starting trigonometric calculations.

##### Problem

Find angle A of the right triangle below. Then calculate angle B and the length of the hypotenuse c. Lengths are in meters. Round results to one decimal place.

The right triangle ABC has a right angle labeled C, positioned at the lower-left side of the triangle. Angle A is at the top-left and angle B at the lower-right side. The lengths of the sides are AC=3, CB=7, and AB=lower case c.

Reminder:

### Probability

prb

This key displays two menus: PRB and RAND.

PRB contains the following options:

 nPr Calculates the number of possible permutations of n items taken r at a time, given n and r. The order of objects is important, as in a race. nCr Calculates the number of possible combinations of n items taken r at a time, given n and r. The order of objects is not important, as in a hand of cards. ! A factorial is the product of the positive integers from 1 to n. n must be a positive whole number ≤ 69.

RAND contains the following options:

 rand Generates a random real number between 0 and 1. To control a sequence of random numbers, store an integer (seed value) ≥ 0 to rand. The seed value changes randomly every time a random number is generated. randint( Generates a random integer between 2 integers, A and B, where A ≤ randint ≤ B. Separate the 2 integers with a comma.
##### Examples

To correct the error, note the error type and determine the cause of the error. If you cannot recognize the error, use the following list, which describes error messages in detail.

Press clear to clear the error message. The previous screen is displayed with the cursor at or near the error location. Correct the expression.

 ARGUMENT A function does not have the correct number of arguments. DIVIDE BY 0 You attempted to divide by 0. In statistics, n = 1. DOMAIN You specified an argument to a function outside the valid range. For example: For x√y: x = 0 or y < 0 and x is not an odd integer. For yx: y and x = 0; y < 0 and x is not an integer. For √x: x < 0. For LOG or LN: x ≤ 0. TAN: x = 90°, -90°, 270°, -270°, 450°, etc., and equivalent for radian mode. For SIN-1 or COS-1: ∣x∣ > 1. For nCr or nPr: n or r are not integers ≥ 0. For x!: x is not an integer between 0 and 69. EQUATION LENGTH ERROR An entry exceeds the digit limits (80 for stat entries or 47 for constant entries); for example, combining an entry with a constant that exceeds the limit. FRQ DOMAIN FRQ value (in 1-Var stats) < 0 or > 99, or not an integer. OVERFLOW ∣θ∣ ≥ 1E10, where θ is an angle in a trig, hyperbolic, or R right arrow Pr( function. STAT Attempting to calculate 1-var or 2-var stats with no defined data points, or attempting to calculate 2-var stats when the data lists are not of equal length. DIM MISMATCH Attempting to create a formula when the lists are not of equal length. FORMULA The formula does not contain a list name (L1, L2, or L3), or the formula for a list contains its own list name. For example, a formula for L1 contains L1. SYNTAX The command contains a syntax error: entering more than 23 pending operations or 8 pending values; or having misplaced functions, arguments, parentheses, or commas. If using n/d, try using ÷. INVALID FUNCTION Invalid function entered in the function table. LOW BATTERY Replace the battery. Note: This message displays briefly and then disappears. Pressing clear does not clear this message.
