Mode indicators appear in the lower part of the display. The COMP, SD and REG modes can be used in combination with the
angle unit modes.
Be sure to check the current calculation mode (SD, REG, COMP)
and angle unit mode (DEG, RAD, GRA) before beginning a
The memory area used for calculation input can hold 79 “steps”.
Whenever you input the 73rd step of any calculation, the cursor
changes from ” to to let you know memory is running low. If
you still need to input more, you should divide your calculations into
two or more parts.
Making corrections during input
Use and to move the cursor to the location you want.
Press to delete the number or function at the current cursor
Press to change to an insert cursor . Inputting something
while the insert cursor is on the display inserts the input at the insert
Press , , or returns to the normal cursor from
the insert cursor.
Pressing or recalls the last calculation you performed. You
can then make any changes you want in the calculation and
Pressing does not clear Replay memory, so you can recall the
last calculation even after you press .
Replay memory is cleared whenever you start a new calculation,
change to another mode or turn off power.
Pressing or after an error occurs displays the calculation
with the cursor positioned at the location where the error occured.
Exponential display formats
This calculator can display up to 10 digits. Larger values are automatically
displayed using exponential notation. In the case of decimal values, you
can select between two formats that determine at what point exponential
notation is used.
Press (or ) to select NORM 1 or
With NORM 1, exponential notation is automatically used for integer values
with more than 10 digits and decimal values with more than two decimal
With NORM 2, exponential notation is automatically used for integer values
with more than 10 digits and decimal values with more than nine decimal
All of the examples in this manual show calculation results using the
NORM 1 format.
Whenever you press after inputting values or an expression, the
calculated result is automatically stored in Answer Memory. You can
recall Answer Memory contents by pressing .
Answer Memory can store up to 12 digits for the mantissa and two
digits for the exponent.
Answer Memory contents are not changed if the operation performed
by any of the above key operations results in an error.
