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 : EXTKSRT002-18P ( 18 pin extension cord ) For connection between mechanism assembly and main board assembly. Check for mechanism driving section such as motor ,etc..
Disassembly method
1. Remove the bottom cover.
2. Remove the front panel assembly.
3. Remove the top cover .
4. Install the front panel.
5. Confirm that current is being carried by connecting an extension cord jig.
Note Available to connect to the CP701 connector when in­stalling the front panel.

1. azimuth adjustment
Conditions
Test tape: SCC-1659 VT703(10kHz)
Adjustment and Confirmation methods
Head height adjustment 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.
Load the SCC-1659 mirror tape. Adjust with
1. 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.
After switching from REV to FWD then to
2. REV, check that the head position set in procedure 1 is not changed. (If the position has shifted, adjust again and check.)
Adjust with azimuth adjustment screw B so
3. that line B of the mirror tape runs in the center between Lch and Rch in the forward play mode.
Head azimuth adjustment
Load VTT724 (VT724) (1kHz) and play it
1. back in the reverse play mode. Set the Rch output level to max.
Load VTT703 (VT703) (10kHz) and play it
2. back in the forward play mode. Adjust the Rch and Lch output levels to max, with azimuth adjustment screw B. In this case, the phase difference should be within 45 .
Engage the reverse mode and adjust the
3. output level to max, with azimuth adjustment screw C. (The phase difference should be 45 or more.)
When switching between forward and
4. reverse modes, the difference between channels should be within 3dB. (Between FWD L and R, REV L and R.)

Tape speed and wow flutter confirmation
Play back frequency response confiramation
When VTT721 (VT721) (315Hz) is played
5. back, the level difference between channels should be within 1.5dB.
Test tape: VTT712 (3kHz)
Test tape: VTT724 (1kHz) VTT739 (63Hz / 1kHz / 10kHz)
The tuner section is of an adjustment-freedesign. In case the tuner is in trouble, replace the tuner pack.
Check to see if the reading of the F, counter /
1. wow flutter meter is within 3015 3045(FWD / REV), and less than 0.35% (JIS RMS).
In case of out of specification, adjust the
2. motor with a built-in volume resistor.
Play test tape VTT724, and set the volume
1. position at 2V.
Play test tape VTT739 and confirm.
2. 1kHz / 10kHz: -1 3dB, 1kHz / 63Hz: 0 3dB,
When 10kHz is out of specification, it will be
3. necessary to read adjust the azimuth.
