Before Using The Calculator; Initial Setup - LEXIBOOK SC300i Bedienungsanleitung

Before using this calculator for the first time, remove the static label from the LCD screen
and pull the battery tab located on the battery door. Once the battery tab is removed, the
unit will turn on automatically.
Note: If you are unable to pull the battery tab, open the battery door and try again.
Key Notation Used in this Manual
In this manual, specific notation is used to describe operations made on the calculator.
On the front of the calculator you will see some keys (numbers, operations, functions
etc.) and some writings (functions, memories etc.) above or on the side of the key. How
to use this features will be described as follows:
As shown above, please note that only the second function is indicated following
For example, notation used to compute "three times Pi" is:
Power On and Off
Press
Clearing Methods
There are three clearing methods as follows:
Calculation Priority Sequence
This calculator will compute a formula by using some priorities. In fact it employs true
algebraic logic to calculate a formula in the following order:
1. Function preceded by their argument (X², X
2. Power / Root : y
3. Implied multiplication of a memory value (2Y, etc...)
4. Functions followed by their argument (sin, cos, etc...)
5. Implied multiplication of a function (2sin30 etc...)
6. nCr, nPr

calculator (excluding statistical data and memory contents in the normal
mode.)
[CA] : Clears the values in the calculator, excluding independent memory "M" in
2ndF
the normal mode. Clears all statistical data in the statistical mode.
Delete the digit on the right of a number.

Pending Operations
Operations that cannot be performed immediately due to priority levels or to parentheses
must be set aside temporarily (pending operations). This calculator can hold up to 16
calculations and up to 8 numeric values. (8 values in normal mode and 4 values in
statistics mode.)

Mode Selection
This calculator can operate in any of the three operation modes described below. To
select the mode, press
MODE
mode.
Normal mode:
MODE 1
Used to perform arithmetic operations, substitute arithmetic and
[π]
2ndF functions.
3 X =
MODE 2 Statistics mode:
Used to perform statistics calculations. The STAT indicator appears on
top right of the display.
Currency conversion mode.
MODE 3
Selection of the Display Notation
This calculator has the following four display notation systems for the display values.
FIXed decimal point system:
A value is displayed with the number of decimal places specified. The FIX
indicator appears.
SCIentific notation system:
A value is displayed using scientific notation. The SCI indicator appears. The
mantissa of the value is displayed with the number of decimal places specified.
ENGineering notation system:
A value is displayed using engineering notation. The ENG indicator appears. The
mantissa of the value is displayed with the number of decimal places specified
and the exponent is set to a multiple of 3 for display.
Floating point system:
A value is displayed without regard for the number of decimal places specified.
None of the FIX, SCI or ENG indicators appears. Scientific notation is used if the
values are not in the range 0.000000001
The display notation is changed by pressing
displayed or after clearing the values in the calculator with
