Removal
ESD procedures must be used when removing or replacing PWBs. Damage to electrical com-
ponents is likely if static discharge reaches components.
Always wear a wrist strap to protect electrical parts from static damage. If a wrist strap is not
available, touch some metallic parts to discharge the static electricity before servicing.
A loss of serialization and billing data will occur, and disable the machine, if both the ESS PWB
with EPROM and the MCU PWB with EPROM are replaced at the same time.
1. Switch off the power and disconnect the power cord.
2. Remove the following covers (Figure
