NOTE: The following precautions should be taken whenever Printed
Circuit (PC) Boards are being handled or replaced.
• Always use an ESD safe container when transporting boards
from one location to another.
• No boards should be removed from their containers except at an
approved static station or where personnel and machine are
properly grounded.
• At minimum, use a wrist strap grounded to the washer when
removing and/or replacing PC Boards.
NOTE: Failure to follow the above precautions may result in
electrostatic damage to the Printed Circuit Board. If a static dis-
charge happens to go through an Integrated Circuit (IC) and the
transient current pulse is not effectively diverted by protective
circuitry, the current from the discharge can flow through the board
and raise the temperature of internal junctions to their melting point.
Damage can range from latent degradation to complete destruc-
tion.
NOTE: Before removing EPROM memory, turn washer ON and
press bottom portion of the Printer Function rocker switch to obtain
a copy of the current washer cycle settings.
1. Take note of the actual washer configuration by entering the
Factory Setup mode.
