Introduction
In addition to regular calculator functionality, this Checkbook Calculator
provides you with the ability to maintain six independent account
memories. These memories can be used to maintain checking, savings and
credit card balance information. Information stored in these six permanent
memories is saved continuously, whether the calculator is on or off, as long
as the battery is viable.
This Checkbook Calculator also has a password key which allows you to
enter a secret number. This password protection prevents someone from
accessing the financial information stored in the device’s memories.
Maintenance and Power Source
Please read the recommendations to ensure trouble-free operation of your
Checkbook Calculator.
Clean your calculator using a soft dry cloth. Do not use organic
solutions such as alcohol.
Your calculator should be kept in areas free from extreme
temperature changes, dusty and damp areas.
Should service of your calculator be required, see the Limited

the batteries, unscrew the cover plate on the back of your calculator and
insert batteries with the positive side facing up. Your calculator uses one
of any of the following button cell batteries : GP189A GPI, AG10, AG130.
When you are finished replacing the batteries, replace the cover plate and
screw it back into place.
