5.7.8.3 When Replacing the SRAM PCB
When the SRAM PCB is replaced, all data in its
memory will be lost (file-related, user mode-related,
service mode-related, history-related files). There
will be no error operation, and initialization will take
place automatically.Å@
If you pull out the SRAM PCB from machine B and
mount it to machine A, the PCB will be initialized
and be rendered useless for machine A or B. Take
full care.
1) When you turn on the power after replacing the
SRAM PCB, the machine will perform automatic
initialization and will indicate a message on its
panel to the effect that you are to turn off and then
on the power switch found on its right side.
Follow the message and turn off and then on the
machine.
2) Using service mode, initialize the RAM.
