Information for using a car audio service jig
(1) We're advancing efforts to make our extension cords common for all car audio products.
Please use this type of extension cord as follows.
(2) As a U-shape type top cover is employed, this type of extension cord is needed to check operation of the mechanism assembly
after disassembly.
(3) Extension cord : EXTKSRT002-6P ( 6 pin extension cord ) For connection between mechanism assembly3. Extension cord :
EXTKSRT002-6P ( 6 pin extension cord ) For connection between mechanism assembly and main board.
(4) Check for mechanism driving section such as motor ,etc.
Disassembly method
(1) Remove the front panel assembly.
(2) Remove the bottom cover.
(3) Remove the front chassis assembly.
(4) Remove the heat sink.
(5) Remove the main board.
(6) Reattach the heat sink with the screw B. (Refer to Disassembly method.)
(7) Reattach the front panel assembly.
(8) Confirm that current is being carried by connecting an extension cord jig.
NOTE:
Available to connect to the CJ701
CAUTION :
Be sure to attach the heat sink on the power amplifier IC of a main board when supplying the power.
If voltage is applied without attaching the heat sink, the power amplifier IC will be destroyed by heat.

Head height adjustment
Adjust the azimuth directly. When you
adjust the height using a mirror tape,
remove the cassette housing from the

After installing thecassette housing,
perform the azimuth adjustment.
Load the SCC-1659 mirror tape. Adjust with

mirror tape runs in the center between Lch
and Rch in the reverse play mode.

the phase difference should be within 45 .
Engage the reverse mode and adjust the

adjustment screw C.
(The phase difference should be 45 or
more.)
When switching between forward and
