8.15. SERVICE 13: Device Check
Checks for malfunctions at the main PCB´s IC8 and IC4, and
peripheral circuitry.
1. Execute the "8.3 SERVICE 1: EL Display Mode Switching"
peripheral circuitry.
1. Execute the "8.3 SERVICE 1: EL Display Mode Switching"
procedure so that EL is always ON.
2. Execute the SERVICE 13 menu as described in section 8.2
(Entering The Service Mode).

· The check results (Fig.S21) then display approximately
· The device check screen displays.
· The check results (Fig.S21) then display approximately
15 seconds later.
* Checks occur in the SRAM check, ASIC check, A-Core
check order. If an error is found, the check operation
check order. If an error is found, the check operation
stops at that point.
3. Open the battery cover to end the procedure.

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).

1001
SD card initialization failure
Hardware/software
Try changing the SD-card, and turning the power
OFF and ON. If the error persists, try removing the
battery and installing it again. If the error still
persists, perform a device check.
OFF and ON. If the error persists, try removing the
battery and installing it again. If the error still
persists, perform a device check.
1002
MBR reading error (normal)
Hardware/software
Try changing the SD-card, and turning the power
OFF and ON. If the error persists, try removing the
battery and installing it again. If the error still
persists, perform a device check.
OFF and ON. If the error persists, try removing the
battery and installing it again. If the error still
persists, perform a device check.
1003
FAT reading error (normal)
Data
Try changing the SD-card, and turning the power
OFF and ON. If the error persists, try removing the
battery and installing it again. If the error still
persists, perform a device check.
OFF and ON. If the error persists, try removing the
battery and installing it again. If the error still
persists, perform a device check.
1004
DIR entry reading error (normal)
Hardware/software
Try changing the SD-card, and turning the power
OFF and ON. If the error persists, try removing the
battery and installing it again. If the error still
persists, perform a device check.
