1.2 Conventions used in this manual

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 indicated in

round brackets e.g.

(Row 2, Column 1)

Let’s take the instance of the [ab/c] key below:

[ab/c]Enter Fraction. This is the primary or first

function of this key.

[d/c] ([2nd][ab/c]) Convert between mixed number and

improper fraction. This is the second function of the

[ab/c]key and is invoked by pressing the [2nd] and

[ab/c] keys.

[F◄►D] ([3rd][ab/c]) Fraction Exchange Decimal. This

is the third function of the [ab/c]key and is invoked

by pressing the [3rd] and [ab/c] keys.

Speech output is denoted by enclosing it in quotes

e.g. “All Clear”.

2.1 Shipping List

You should have received the following items in

your Calculator package:

1. Orion TI-36X Talking Scientific Calculator

2. This Users Manual

3. A 3.5 inch floppy disk containing ASCII and

Microsoft Word versions of this manual

4. Earphone

2.2 Orientation of the unit and its Controls

This section will familiarize you with the location

and functions of the primary controls of your Orion

TI-36X Talking Scientific Calculator.

First, open the protective snap cover. This cover fits

tightly and can be opened by pressing down the

upper end of the cover gently with your thumb, and

pulling up on the bump at the top of the cover with

your fingers. Then, 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 hand 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.

2.3 Power supply and Charging

Your Orion TI-36X calculator has a built-in re-

chargeable battery pack, which gives you the

freedom of carrying the calculator and working

anywhere and also relieves you from having to

replace the batteries frequently.

- 7 - - 8 -

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-36X. 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-36X 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, indirect 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 on the 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-36X 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 over 6 hours of continuous use. It is

generally not necessary to change the batteries

inside the unit until they have completed at least

500 charge and discharge cycles. At this point they

- 9 - - 10 -

may become "tired" resulting in a decrease in the

duration of use before they need to be recharged.

The batteries in the unit CAN NOT BE

REPLACED BY THE USER. Please contact Orbit

Research for battery replacement.

2.4 Switching on the unit

To switch ON the Orion TI-36X Talking Scientific

Calculator press the ON/AC key until you hear a

beep and release it immediately. The ON/AC key is

located 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

ON/AC key you will hear the unit first give a beep

and then say “Power On” after 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. For fast shutdown of the unit,

press both the buttons – LEARN/MODE and

REPEAT/OFF – simultaneously.

2.5 Volume control

Speech volume can be controlled by the volume

control thumb-wheel on the left hand 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 hand 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.

2.6 Learning-mode

The Orion TI-36X 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

- 11 - - 12 -

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-on). 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-36X 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.

2.7 Orientation of Keys

The Orion TI-36X has 40 keys arranged in 8 rows

and 5 columns. 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 7th row and first

column), 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], [3rd] 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-36X calculator can be used in six

different modes viz. Decimal (the default mode at

power-on), Hexadecimal, Octal, Binary, One-

Variable Statistics and Two-Variable Statistics.

These modes can be selected using the [3rd]key.

The [3rd] key is located in the 8th row and 1st

- 13 - - 14 -

column. The six modes can be set by pressing the

[3rd]key followed by other keys as shown below.

[3rd][X] Binary mode

[3rd][)] Octal mode

[3rd][(] Hexadecimal mode

Note: Some operating features such as

trigonometric functions are available only in

decimal mode and statistics mode. You will hear a

warning tone or the word “Error” if you attempt to

use a feature that is not available.

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 [X2]key gives the mean in

One Variable Statistics Mode, the mode is shown in

round brackets.
