SciPlus-3300 Scientific Calculator – User Guide
Getting Started
Your SciPlus-3300 calculator performs a wide variety of mathematical, statistical, and trigonometric calculations. The
speech output provides an audible description of all operations.
The SciPlus-3300 also enables you to evaluate mathematical functions.
This User Guide will explain how to get the best from your calculator. Let’s first get familiar with the SciPlus-3300 controls.
The USB port is for charging the calculator. You will find this on the left-hand edge of the SciPlus. On the right-hand edge
is the earbud jack.
Throughout this manual we will refer to keys within square brackets by their name, row number, and column number.
For example, the POWER button is [POWER ON,2,8]. Note that once the calculator is turned on, this same key becomes
[CLEAR,2,8]. The top left key is the SECOND button, which gives some keys an alternate function. For example [SECOND,
POWER OFF,2,8] will turn off the calculator.
Note that the top row has only six keys in it. Rows two through five have eight keys.
Learning Mode
If you press and hold [SPEECH,3,8] for five seconds the SciPlus-3300 enters “Learning Mode”. In this mode, the keys do
not operate normally. Rather, they simply announce (through the earbuds) their function. This allows you to become
comfortable navigating the keyboard. If you precede a key with [SECOND,1,1] it will speak its alternate function if one
exists. Press and hold [SPEECH,3,8] again to return to normal operation.

Charging your SciPlus-3300
Charging the calculator is easy. Your SciPlus-3300 calculator includes a USB Wall Charger and cord. Simply plug the USB
wall charger into a regular outlet, and plug the USB cable into the SciPlus-3300. The calculator should fully charge
overnight. On a full battery the SciPlus-3300 will operate for about 6-8 hours of continuous use. Note this is less than an
ordinary calculator because of the bright backlight, which makes the display much easier to read.
When the SciPlus-3300 is charging, you will notice the battery symbol is animated. The battery is completely charged if
when the animation stops and three solid bars are shown. When the battery requires recharging, you will hear a beep in
your earbuds every 30 seconds.
Note: If your SciPlus has been unused for a very long time, you may need to charge it for a while before it will even turn
on. When this happens, make sure you “RESET” the SciPlus by carefully inserting a paperclip into the hole on the
backside of the calculator. This restores factory settings to ensure proper operation.
Auto Shutoff
Your SciPlus-3300 calculator will automatically shut off after a few minutes of inactivity. Many of the calculator’s current
settings such as the angle mode, number format, etc., will be saved, so that it will turn on again in the same state. Values
stored in memory and the statistics table are also saved.
If the calculator is left off for an extended period (typically many weeks), these settings may be lost.

The SciPlus-3300 Display
The SciPlus-3300 screen has four lines. The bottom line with
the flashing red cursor is where you enter expressions. The
other three lines show the results of previous operations.
Once you press [ENTER,6,6] an expression is evaluated and
its result is moved up a line, leaving the bottom line empty
to enter another expression.
Note: When lengthy expressions or results do not fit on the
screen you will notice a red left arrow or a red right arrow as
shown in the diagram. This is to indicate that characters are
hidden to the left or right. Use the green keys [LEFT,5,7],
[RIGHT,5,8], [UP,4,7], and [DOWN,6,7] to move the cursor.
In expressions use [BACKSPACE,6,8] to delete what is to the
left of the cursor and edit the expression.
The characters above the horizontal red line at the top of the screen show the status line of the calculator. If the battery
symbol is animated, this indicates that the battery is being charged. Some of the characters in the status line may not
appear at all times. For example, if there is no entry in memory, or if the statistics register is currently empty, these items
will not appear.

SciPlus-3300 Operations
The SciPlus-3300 follows the “BEDMAS” rule for order of operations:
Brackets – Exponents – Divide – Multiply – Addition – Subtraction
Many of the SciPlus-3300 keys have two functions. The lower function appears in a white font. The alternate function
appears in a yellow font. To access this function, the [SECOND,1,1] key must first be pressed. You will notice a yellow up
arrow in the status line when you do this. Throughout the key descriptions below, if a key symbol appears in a yellow
background, this indicates that the [SECOND,1,1] key must be used.
Soft Keys
The keys [A,1,2], [B,1,3], [C,1,4], and [D,1,5] do not have a specific function. Instead, labels at the bottom of the display
define the function of these keys. If there are no labels, these keys will not do anything. You will use these keys when
adjusting the SciPlus-3300’s settings, and for memory and statistics operations, and when using the [FUNCTION,4,8]
feature.

Working with Previous Results
When entering expressions in the bottom line, it’s very easy to use the results of previous calculations displayed in the
lines above it. Using the [LEFT,5,7] and [RIGHT,5,8] keys, position the cursor at the location in the expression where you
wish to insert a previous result. Now, using the [UP,4,7], and [DOWN,6,7] keys, select the previous result that you wish
to insert into the current expression, and press [ENTER,6,6].
Implied Operators
In some cases there is no need to enter [MULTIPLY,3,6] in an expression. Here are some examples:
2 (3+1) is the same as 2 x (3+1)
2 sin(30) is the same as 2 x sin(30)
2 π is the same as 2 x π
( 3 + 2 ) ( 7 - 3 ) is the same as ( 3 + 2 ) x ( 7 - 3 )

Speech Output
Your SciPlus-3300 will automatically read the results of expressions when they are evaluated. You will also notice that
the speech output describes settings screens, etc., when they appear. At any time, pressing a button to continue
operations will halt the speech output. To replay previous results, simply use the [UP,4,7], and [DOWN,6,7] keys to
highlight the line to be read, and select [SPEECH,3,8].
Turn speech output on/off: [SECOND,1,1] [SPEECH,3,8]
Read status line: [SECOND,1,1], [SETTINGS,1,6]
HINT: Always ensure that the volume control on your ear buds is turned up.
