Clearing Memory
Before you use your NR-500 Series ECR for the first time, you must perform a memory all
clear to insure that all totals and counters are cleared and that the default program is
installed.
CAUTION: The procedures described in this area are security sensitive. Clearing
the NR-500 Series memory after the register is put into service will erase all
programming as well as totals and counters. Do not share this information with
unauthorized users and distribute the “SERVICE MODE” only to those you may
want to perform these functions.
1. Move to the SERVICE MODE.
2. Turn the power switch located on the right side of the register to the OFF position.
3. Press and hold the key position where the CHECK key is located on the default
keyboard layout.
4. Continue to hold the appropriate key while turning the power switch to the ON
position. The message “RAM ALL CLEAR" displays.
5. Press the upper left key of the keyboard, then the lower left key, then the upper
right key, and finally press the lower right key.
