5-1 Reference
5-1-1 The type of remote control ass’y
1. Remote control ass’y (AC93-10039Y/69099-633-252)
is specified as a service jig in the service manual of
X-5/X-6(DX5-R/DX5-RC/DX6-R/DX6-RC) chassis.
(See Fig. 5-1)
2. Normal remote control ass’y for X-7/X-8
(DX7-R/DX7-RC/DX8-R/DX8-RC) chassis.
(See Fig. 5-2)
5-1-2 How to identify between normal
remote control ass’y and multi
remote control ass’y for X-7/X-8
chassis (See Fig. 5-2)
1. The color of some buttons related to TV function are
gold.
2. Audio button is added instead of the test button
