8.7. SERVICE 5: Settings
Initialization (all settings)
Initializes the model & region settings, as well as resume
information, and the tuner´s preset frequency.
* Unlike the initialization item at the standard mode´s setting
menu, the tuner preset information is also initialized to the
factory settings.

(Entering The Service Mode).
· After settings are initialized, the power is automatically
turned OFF.

SERVICE 6: Settings Readout

Verifies that settings information has been written to the IC4
(Flash ROM) without error.
1. Execute the SERVICE 6 menu as described in section 8.2
(Entering The Service Mode).
· Reads out the IC4 (Flash ROM) settings information,
and writes it to the SD-card.
· The power is then automatically turned OFF.
2. Use the accessory USB cable to connect the audio player
to the personal computer.
3. From the personal computer, verify that the default settings
file (FLASH_RD.BIN) has been written to the SD-card.
* The presence of the FLASH_RD.BIN file on the SD-card
indicates that the settings information has been written to the
IC4 (Flash ROM) without error.
If the FLASH_RD.BIN file is not present on the SD-card,
execute the "8.9. SERVICE 7: Default Settings Writing"
procedure.
8.9. SERVICE 7: Default Settings
Writing
Writes the service mode SD-card´s default settings file
(FLASH_RD.BIN) to the IC4 (Flash ROM).
The model & region settings are written to the audio player by
this procedure.
1. Execute the SERVICE 7 menu as described in section 8.2
(Entering The Service Mode).
· Writes the default settings to the IC4 (Flash ROM), and
the power is then automatically turned OFF.
2. Execute the "SERVICE 6: Settings Readout" procedure to
verify that the default settings have been written to the IC4
(Flash ROM).
* If the "SERVICE 6: Settings Readout" procedure reveals that
the FLASH_RD.BIN file has not been written to the SD-card,
this indicates 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).

procedure so that EL is always ON.
2. Execute the SERVICE 8 menu as described in section 8.2
(Entering The Service Mode), in order to display the card´s
detection count screen (Fig.S7).
3. Remove the service mode SD-card, then insert it again.
