each rate.

•Only one rate can be stored. If you enter a new rate, the previous

rate will be cleared.

ADD MODE SELECTOR:

“A/+” position – Effective only in addition and subtraction:

Use of the A/+ mode permits addition and subtraction of

numbers without an entry of the decimal point. When the

A/+ mode is activated, the decimal point is automatically

positioned according to the decimal selector setting.

EXAMPLES: Set A/+- •-A/x to A/+

A. Set decimal to 2

Enter 123456 Tape prints 1,234.56 +

B. Set decimal to 3

Enter 123456 Tape prints 123.456 +

Use of the , , and keys will automatically override

the Add mode and decimally correct answers will be

printed at the preset decimal position.

EXAMPLES: Set A/+- •-A/x to A/+, 5/4

A. Set decimal to 2

Enter .1234 Tape prints 0.1234 ×

100 100.=
