For disassembling and assembling of MECHANISM ASSEMBLY, refer to the SERVICE MANUAL No.86700 (MECHANISM ASSEMBLY). Regarding service information other than these sections, refer to the service manual No. YF008 (GR-D73EX).

lso, be sure to note important safety precautions provided in the service manual.

NOTE :

There are two types of VF(COLOR) ASSEMBLY used for this model: S type and K type. Prior to repair operation related to VIEW FINDER, be sure to see the VF(COLOR) ASSEMBLY and Parts List. Methods to distinguish the two types are as follows:

1. Distinction based on EEPROM DATA (EEPROM utility). (*1)

2. Distinction based on a part number of the MONI-C BOARD ASSEMBLY.

3. Distinction based on a sticker attached to the VF(COLOR) ASSEMBLY.

S TYPE K TYPE

EEPROM DATA (*1) ADRS 3CCH:01H ADRS 3CCH:05H

MONI-C PWB YB10447 SERIES YB10453 SERIES

VF(COLOR) ASSY (*2) STICKER : BLUE STICKER : PINK

(*1) It is necessary to confirm the original data (before repair work) of EEPROM. (*2)The sticker can be confirmed by removing the COVER (UPPER). Be careful, as stickers are not attached to all models. If there is no sticker attached, distinguish the two types by confirming the EEPROM DATA or the part number of MONI-C BOARD ASSEMBLY.
