6. PROTECTION

a. Memory overflow protection

If the overflow occurs in the memory calculation, the data before the calculation is retained.

b. Statistical overflow protection

If the overflow occurs in the statistical calculation, the data before the calculation is retained.

7. THE NUMBER OF DIGITS OF THE INTERNAL RETAINED DATA.

The number of the digits of the mantissa of the displayed data is a maximum of 10 digits, but the available data

for successive calculations is the internally retained data.

The number of digits of the mantissa of internally retained data is as follows:

a. Data input

Maximum

10 digits

b. Arithmetic

Maximum

10 digits

c. Engineering function

d. Statistical function

e. Complex number function

f. Memory calculation

g. Number of random

Maximum

3 digits

8. AUTO CLEAR

When the power supply is suddenly turned on an auto clear routine is executed to initialize as DEC mode, no

TAB, floating, and DEG modes.

9. POWER OFF FUNCTION

a. Auto power off

About 7.5 minutes after operation is ended by pressing the key, the power supply is turned off.

b. OFF

Pressing this key will stop the oscillator. (Memory safe guard)

c. ON

Pressing this key will wake the oscillator and initialize.
