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.
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).

PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
"VCD PWB" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWB and
service manuals. The alphabetical character following LF shows the type of lead-free solder.
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder
may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 C, we recommend you to use a
dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station
or service branch in your area.
3. Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 C which is higher than the conventional lead solder by 40 C,
and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of
time. However, Since the land may be peeled off or the maximum heat-resistance temperature of parts may be exceeded,
remove the bit from the PWB as soon as you confirm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corrected. Make sure to turn on and off the
power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use
of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.

3. CD SECTION
•Adjustment
Since this CD system incorporates the following automatic adjust-
ment 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. CD ERROR CODE DESCRIPTION
* 'CHECKING'
If Error is detected, 'CHECKING' will be displayed instead of 'ER-
CD**'. 'ER-CD**' display will only be displayed when error had been
detected for the 5th times.
Error Explanation
01 When Pickup set inner position, inner switch cannot detect
'ON' level for 10 secs.
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.
31 When it change to CD function, DSP cannot read initial data.

2.2. How to remove CD Disc (See Fig. 2~6)
1. When CD is at play position, rotate reduction gear C clock-wise as
shown in Figure 2 Until disk tray is at ‘STOCK’ position, then rotate
the gear further to eject the disk tray (Figure 6) so that CD can be
removed from the tray.
2. In another case, if CD mechanism is at tray No. 1 play position and
to remove CD located in tray No. 3, the procedure is as follows:
If the gear up down board is located at tray No. 1 position, then
rotate Reduction gear C clock-wise until Disc tray is at stalk
‘STOCK’ position. Rotate reduction gear D clock-wise (Figure 3) to
move the CD mechanism to tray No. 3 position. This is confirmed
by checking the gear up down board position Base on the marking
as indicated on the main chassis as shown in Figure 4.
• Usually changer is covered with top plate. As for reference pur-
pose, we exclude the top plate for easy viewing. (Figure 5,6)
