REP 9.1.2 MCU PWB EPROM
Removal
CAUTION
Damage to electrical components is likely if static discharge reaches components. ESD proce-
dures must be used when removing or replacing PWBs.
Always wear a wrist strap to protect electrical parts from static damage. If a wrist strap is not
available, touch some metallic parts before servicing to discharge the static electricity.
CAUTION
A disabled machine with loss of serialization and billing data occurs if both the ESS PWB with
EPROM and the MCU PWB with EPROM are replaced at the same time.
NOTE: Refer to REP 9.1.1 to remove or replace the MCU PWB EPROM (Figure 1).
