Main Adjustment

Adjustment and confirmation matter
(1) Auto adjustment method

the DVD player in the following matter:

1. Initialize the DVD player in the following matter:

1) Make sure that no disc is on the tray.

2) Insert the power pulag to the outret while pressing "PLAY" and "OPEN/CLOSE" button at the

(2) Confirmation of DVD RF level

1.The oscilloscope is connected between "1"(RFOP) of
CN104 and "2"(GND).

2.Reproduction of the test disc (VT-501)
made by JVC.

3.It is confirmed that RF LEVEL is 350mVp-p 150mVp-p.

4.When there is disorder in the waveform road cuts etc,
test disk is exchanged and measured.

(3) Confirmation of CD jitter level and RF level

1. The CD jitter meter is connected between "11"(GND)
of CN104 and "12"(FLTOUT).
The RF level is observed at the same time.

2.The first test disk(CTS-1000) made of JVC is reproduced.

3.It is confirmed that RF LEVEL is 360 100mVp-p.

5. When there is disorder in the waveform road cuts
etc, test disk is exchanged and measured.

Note: If the FL indicator display stops and remains at "TEST 0", unplug the power

cord from the outlet and after waiting at least 1 second, plug it in again. After
the tray open/close procedure has completed, unplug it again and then
perform the initialization procedure again.

3) Press the "OPEN/CLOSE" key of the main unit to draw the tray out.
*Place the test disk (VT-501) on the tray and then press the "OPEN/CLOSE" key.

(Note: Pushing the tray to close it is not possible.)

4) Press the "PLAY" key of the main unit.

5) The "JIT 0000" is displayed on the FL indicator.

"Flap adjustment" of the Pick-up guide shaft adjusts
"Tangential adjustment machine screw" A and
"Tilt adjustment machine screw" B from the
DVD Mechanism A'ssy bottom.

1. The part at the center on the DVD test disc is
reproduced.

2.The flap adjustment screws is turned alternately
and adjusted like clearly seeing the waveform of
CN104"1" to the way.

Note

1.The tangential adjustment is done finish and,
then, tilt is adjusted.

2.The repeat the adjustment 2-3 times,for best
result.

3.The final adjustment should be tilt adjustment.

(5) About keeping the disc

As for the DVD test disc, plane accuracy is demanded.Please note the keeping place on the disc.

1. Please do not put the disc directly on the work desk etc. after uses .

2. To keep the planarity of the disc, politely handle ,and please put in a special case and keep
the disc vertically after uses .
Please keep keeping the disc in a cool place where direct sunshine and the air-conditioning
wind do not drive.

3. When the disc curves,an accurate adjustment cannot be done.

Please exchange for a new test disc and adjust optics.

4. Other discs might not be able to be reproduced when adjusting on a curved disc.

Point of adjustment
* Please execute the static electricity protection measures before starting the adjustment.
* When the following parts are exchanged,optical adjustment "Adjust the flap of the disc motor"
is necessary.

1.The disc motor was exchanged.

2.The laser pick up was exchanged.

3.The traverse motor unit was exchanged.

Note

Additionally, please adjust the flap of the disc motor when the picture quality
deterioration is seen .The basic adjustment though, is unnecessary for part exchange
in the traverse.

An optical adjustment in the laser pick up cannot be done.

Please adjust the flap of the disc motor after exchanging the laser pick up.

* When the traverse unit is exchanged, the adjustment is basically unnecessary.
