The Battery Back-Up System - Royal 101cx Owner's Manual

__________________________________________________________________
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, such as PLU and department information programmed in the register.
The memory is protected by 3 standard "AA"(1.5-Volt) batteries that should be installed before programming the register.
Batteries are not included with the register. These must be purchased separately.
When properly installed, these batteries provide back-up power to the register memory if the power cord is accidentally
disconnected or if a power interruption occurs.
information 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 ensure proper memory protections, batteries should be
replaced with new batteries after any lengthy interruption of power, once power has been restored, or once a year.
TO INSTALL OR REPLACE BATTERIES:
1. Be sure the cash register is plugged-in and there is power to the machine.
2. Move the control switch to the "R1 or "R2" position.
3. Open the printer cover as described on Page 10.
4. Remove the paper roll from the compartment.
5. Remove the battery cover, located on the left side of the printer compartment.
6. Position the batteries as indicated (Figure C), making sure that the positive and negative poles are aligned
correctly.
7. Replace the battery cover by sliding down and locking into position. (See Figure D).
8. Put the paper roll back into the compartment and close the printer cover.
NOTE: It is important that the unit is plugged in before the batteries are first installed and when
replaced.
NOTE: In order to assure continuous battery back-up protection, it is important that the batteries be changed at least
once every year.
