GETTING STARTED
1. Check the Current Calculation Mode
Be sure to check the status indicators that indicate the
current calculation mode (DEG, BIN, STAT and CPLX)
and display formats setting (Floating mode).
Note! If you get into trouble, hold + to reset
the calculator.
2. Key Symbols
The "D" key is colored in gray.
To use a function printed above a key in gray,
press the key while in Hexadecimal mode.
Note:
The blue keys are active in Statistic mode only. In
Statistic mode ("STAT" indicator lights up), they
work as follows.
Calculate the number of data samples when it is
pressed.
2nd function key: Calculate the summation of
" " data were input when it is pressed
immediately after .
Example
Example
To use a function printed on a key, press the key.
To use a function printed above a key, press the
key while in decimal mode.

Power ON, OFF
Auto Power Off Function
When the calculator is not used for about 7 minutes,
the calculator will automatically power off.
Reset Key: Reset the calculator when
these keys are pressed. The memory is
cleared, and the calculation mode is reset
to Decimal Calculation (Floating mode).
Hold + to reset the calculator.
Turns the calculator off.

Example:
Note!
•Fraction calculation results will be displayed in
decimal format automatically whenever the total digits
of a fractional value (integer + numerator +
denominator + separator marks) exceeds 10.
•can convert the results of fractional calculations
to decimal notation, and vice versa.

Example:
Mixed / Improper Fraction Conversion Key:
It converts mixed fractions to improper
fractions and vice versa. It changes
alternatively each time the key is pressed.
Example:

14
Memory Keys
Independent Memory: The data in the independent
memory is retained even when the calculator is turned off.
Memory Plus and Minus Key: Add or
Substract numbers to the independent
memory.
Memory Recall Key: Retrieve the value
of the independent memory.
Exchange Memory By Display Value:
Replaces the displayed number with the
contents of the independent memory.
Memory Variables: You can assign a specific value
or a calculation result to a variable. There are 6 memory
variables (A, B, C, D, E and F) to store data, results, or
dedicated values.
Store Values Key: To store variable into
memory.
Recall Values Key: To recall the memory
variable.
Example: Using the independent memory:
