Purpose 1 : Used for servicing and repairing of options (such as the
ER-A5RS) which are connected with the main body op-
tion connector.
[Procedure 1]
Use an insulator base as shown in the shaded section when perform-
ing servicing.
To check the option I/F PWB from the solder side, connect the I/F
PWB to OPTCN2. To check from the parts side, connect to OPTCN3.
(Note) The option I/F PWB should be held horizontally so that no
excessive stress is applied to connecting section
.
[Procedure 2]
Put a string between the pop up and the option PWB. Adjust the
length of the string so that the CKOG-6708RCZZ and the option PWB
are not binding. Once verified, then you may proceed with performing
service.
