FUNCTIONAL DESCRIPTION

A). Operation Characteristics

a).Constant Operation

The SC3414 has implied constant mode on +, -, X,H & % operations. The constant is performed automatically

by the "=" key, "%" key, or "%" key without a constant for addition, subtraction and division while the first

operand is the constant for multiplication.

b).Number Entry

Numbericals can be entered up to 12-digit.

c).Memory Protection

In any error detection, the memory contents present before the error detection are protected.

d).Memory Indication

If the memory contents are a number other than zero, "M" is indicated in the sign-digit position.

e).Auto Power Off

If no key is depressed for a specific period of time, the power supply will automatically turn off (pin option). This

time interval up to power-off is 600 sec.
