[4] Handling EEPROM’s in case replacement of PWB is required
- Make sure to remove the EEPROM on PWB purchased as service parts if replacement of PWB
is required. Remove the EEPROM from the PWB attached to the device and mount it to the
new PWB.
Caution: If service parts EEPROM is mounted as it is without initialization, U2 trouble occurs
100% of the time.
It is impossible to clear the “U2 trouble” by executing Sim 16 unless the EEPROM is initialized.
<Procedure>
Remove EEPROM from new PWB.
Remove EEPROM on the PWB attached to the device and mount on new PWB.
* Find a tool you can insert into back
side of the EEPROM (ex. straight
slot screwdriver). Using the tool,
move right and left side of the
EEPROM slowly and gently to
remove from the PWB.
Handle with care so that EEPROM
and PWB won’t be damaged and
pins won’t be bent.
