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.
