We are advancing efforts to make our extension cords comman for all Car Stereo products.
Please use this type of extension cord as follows.
As a U -shape type top cover is employed,this type of extension cord needed to check operation of
the mechanism assembly after disassembly.

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
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
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
that line B of the mirror tape runs in the
center between Lch and Rch in the forward
play mode.

In case of out of specification, adjust the

Play test tape VTT739 and confirm.
1kHz / 10kHz: -1 3dB,

When 10kHz is out of specification, it will be
necessary to read adjust the azimuth.

Load VTT724 (VT724) (1kHz) and play it
back in the reverse play mode. Set the Rch
output level to max.
Load VTT703 (VT703) (10kHz) and play it
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
output level to max, with azimuth
adjustment screw C.
(The phase difference should be 45 or
more.)
When switching between forward and
reverse modes, the difference between
channels should be within 3dB. (Between
FWD L and R, REV L and R.)
When VTT721 (VT721) (315Hz) is played
back, the level difference between channels
should be within 1.5dB.
