3. DIAGNOSTIC CHECK
Service Manual BSM-4100 3.17
OTHER Check
This item checks the clock IC and backup NVRAM (EEPROM). The NVRAM
contains the system setup data. The check program checks correspondence
between write and read data with the stored data retention. Therefore, this check
does not damage the system setup data. If the clock IC and NVRAM have no error,
the “OK” message appears on the screen and current date and time appear at the
top of the screen. If an error message appears, the MAIN board will be faulty.

1. To select the OTHER Check, touch the “OTHER CHECK” key.
The program starts the checking automatically and several minutes later, the
program displays the result of checking.
2. To return to the MANUAL CHECK MENU screen, touch the “RETURN” key.
