CHAPTER 1. GENERAL DESCRIPTION
[1] SAFETY PRECAUTION FOR SERVICE MANUAL
Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class 1 Requirements. However, the following precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.
1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position outer than the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.
2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to shipping.
3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
4) Under no circumstances look directly into the Pickup Lens at any time.
5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result in hazardous radiation
exposure.
[2] VOLTAGE SELECTION
Before operating the unit on mains, check the preset voltage. If the voltage is different from your local voltage, adjust the voltage as follows.
Turn the selector with a screwdriver until the appropriate voltage number appears in the window(110V,127V,220V or 230V - 240V AC).

3. DVD SECTION
• Adjustment
Since this DVD system incorporates the following automatic adjustment functions, readjustment is not needed when replacing the
pickup. Therefore, different PWBs and pickups can be combined
freely.
Each time a disc is changed, these adjustments are performed
automatically. Therefore, playback of each disc can be performed
under optimum conditions.
Items adjusted automatically
1) Offset adjustment (The offset voltage between the head amplifier
output and the VREF reference voltage is compensated inside the
IC.)
* Focus offset adjustment
* Tracking offset adjustment
2) Tracking balance adjustment
3) Gain adjustment (The gain is compensated inside the IC so that the
loop gain at the gain crossover frequency will be 0 dB.)
* Focus gain adjustment
* Tracking gain adjustment
4. DVD ERROR CODE DESCRIPTION
Error Explanation
10* CAM error. Can't detect CAM switch when CAM is moving.
11* When it detect cam operation error during initialize process.
20* TRAY error. Can't detect TRAY switch when TRAY is mov-
ing.
21* When it detect TRAY operation error during initialize pro-
cess.
30 When it change to DVD function, DVD cannot start up.
* 'CHECKING'
If Error is detected, 'CHECKING' will be displayed instead of 'ERCD**'. 'ER-CD**' display will only be displayed when error had been
detected for the 5th times.
