Information for using a car audio service jig
1. For 1995 and 1996, 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 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.
4. Remove the two screws D of the rear panel. (Refer to Disassembly method.)
5. Remove the heat sink.
6. Reattach the heat sink with two screws B. (Refer to Disassembly method.)
7. Install the front chassis and front panel assmbly.
8. Confirm that current is being carried by connecting an extension cord jig.
Note
Available to connect to the CJ701 connector when installing the front panel.
CAUTION :
Be sure to attach a 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"
Note
Adjust the azimuth directly. When you adjust the height using a mirror tape, remove the cassette housing from the
mechanism chassis.
After installing the cassette housing, perform the azimuth
adjustment.

A Line
1. Load the mirror tape (SCC-1659). Adjust with height
adjustment screw (a) and azimuth adjustment screw (b) so
that line "A" of the mirror tape runs in the center between
Lch and Rch in the reverse play mode.
2. After switching from REV to FWD then to REV, check that
the head position set in procedure "1" is not changed.
*If the position has shifted, adjust again and check.
3. Adjust the azimuth screw (b) so that line "B" of the mirror
tape runs in the center between Lch and Rch in the forward
play mode.
"Head Azimuth Adjustment"
1. Load the test tape (VT724: 1kHz) and play it back in the
reverse play mode. set the Rch output level to maximum.
2. Load the test tape (VT703: 10kHz) and play it back in the
forward play mode. Adjust the Rch and Lch output levels
to maximum, with azimuth adjustment screw (b).
In this case, the phase difference should be within 45°.
3. Engage the reverse mode and adjust the output level to
maximum, with azimuth adjustment screw (c).
*The phase difference should be 45° or more.
4. When switching between forward and reverse modes, the
difference between channels should be within 3dB.
*Between FWD Lch and Rch, REV Lch and Rch.
5. When the test tape (VT721: 315Hz) is played back, the
level difference between channels should be within 1.5dB.

2. In case of out of specification, adjust the motor with a built in volume resistor
1. Play the test tape (VT724: 1kHz) back and set the volume

2. Play the test tape (VT739) back and confirm 0 ± 3dB at1kHz/

3. When 8kHz is out of specification, it will be necessary to
readjust the azimuth.
