__________________________________________________________________
During cash register operations, all transaction data for the management report is stored in the register's memory. The memory
also holds all the optional program information. The memory back-up system keeps this information stored in memory when the
cash register is turned off.
The memory is protected by four standard "AA" (1.5-Volt) batteries that must be installed before programming the register.
This register comes with 4 "AA" batteries which, when properly installed, provide back-up power to the register memory if the
power cord is accidentally disconnected or if a power interruption occurs. The daily transactions and locked in grand total will be
retained by the machine without (AC) power because of the memory protection feature. Average battery life protection is
approximately 30 days after power interruption.
TO INSTALL OR REPLACE BATTERIES:
1. Turn the control key to the "open" position, open the printer cover as described on Page 10 and move the control
switch to the "R1 or "R2" position.
2. Remove the battery cover, located at the back of the printer mechanism. (Figure B).
3. Position the batteries as indicated (Figure C) making sure that the positive and negative poles are aligned correctly.
4. Replace the battery cover by sliding down in position. (See Figure D).
5. Close the printer cover.
NOTE: It is important that the unit is plugged in before the batteries are installed.
NOTE: In order to assure continuous battery back-up protection, it is important that the batteries be changed at least once every
year.
