When the calculator is not used for about 7 minutes,
the display is automatically turned off to save power.
Use the
frf) key toturn the display on again.
~ Clear All Key: Clears the contents of the
register and the storage memory and resets
the error lock.

3. Calculation Procedure
3-1 Calculation Priority
The calculation procedure priority is automati-
cally determined by the calculator. This means
that algebraic expressions can be entered just

3-2 Levels
During actual calculation, numbersand calcula-
tion instructions not being processed which are
a low priority, are stored in the stack memory.
This stack memory can store up to 6 levels
of
calculations.
