(Entering The Service Mode), and display the EL display
mode switching screen (Fig.S3).
2. Use the [FWD-Skip] and [REW-Skip] buttons to select
"ON", and then press the [PLAY/STOP] button to execute

ON/OFF control enabled" mode.

8.4. SERVICE 2: Device Key Serial
Number. Display
This display is used to verify that the device key is written to the
main PCB´s IC4 (Flash ROM) without error.
If the device key serial number fails to display, there is a
problem with the IC4 (Flash ROM). As the IC4 (Flash ROM)
cannot be replaced independently, replace the main PCB with
a device key loaded PCB (REP3902A-M).
Note: Main PCB replacement should be performed with
reference to section 7 (Precautions When Executing The
Main PCB Replacement Service).
1. Execute the "8.3 SERVICE 1: EL Display Mode Switching"
procedure so that EL is always ON.
2. Execute the SERVICE 2 menu as described in section 8.2
(Entering The Service Mode), in order to display 5 bytes of
the device key serial number. (Fig.S4).
3. Turn the power OFF to complete the procedure.
