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.

adjustment
confirmation
a) At Forward playmode, using mirror tape, make adjustment
with Azimuth screw A and Azimuth screw B, without curl of 4
parts of head tape guide.
b) At Reverse play mode, using mirror tape, make adjustment
with Azimuth screw A and Azimuth screw B, without tape
curl of 4 parts of head guide.
c) At Forward / Reverse play mode, make confirmation of no
tape curl of 4 parts of head tape guide.
a) At forward play mode, make adjustment of peak of Lch / Rch
output with Azimuth screw A.
* For Oscilloscope litharge corrugation, set 45 as standard.
b) At Reverse play mode, make adjustment of peak of Lch / Rch
output with Azimuth screw B.
* For Oscilloscope litharge corrugation, set 45 as standard.
c) With AC volt meter confirm the difference of output for 4ch
between Lch / Rch at forward play mode and Lch / Rch
Reverse play mode being within 3.0dB.
d) After operation, make confirmation of Lch / Rch azimuth
output being within 1.0dB from adjustment value.
