3 ADJUSTMENT AND CHECKS
aA the
1. Replacement of the pickup assembly
@ Before removing the pickup assembly be sure to solder
-bridge where indicated in the inset (Fig. 3-1) to prevent
the laser diode from being electrostatically damaged.
After replacing the pickup assembly, be sure to unsolder
the antistatic bridge. Or else the laser diode does not
function.
@Before servicing the pickup assembly be sure to prevent
electrostatic-inducer destruction by grounding not. only
test equipment in use but also yourself as shown in
Fig. 3-2. :
* Electrostatic charge drastically shortens the operating
life of the laser diode or possibly results in its
destruction.
@During the transportation, mounting and dismounting
of the assembly, support with your fingers at points
A and B as shown in Fig. 3-3. Be particularly careful
not to touch the actuator, photosensor and LD plate
and do not apply force to them.
@Don’t touch the plated portion of the flat cable end
directly with fingers.
@Use care not to break the flat cable.
@Soldering must be done quickly at less than 30W, 320°C.
@Don’t disassemble the pickup ass’y.
@Don’t apply shock to the pickup ass’y.
@Don’t place the assembly in a place subject to excessive
dust, heat or moisture.

Fig. 3-1 Fig. 3-2
2. Objective
@Laser beams are similar to infrared rays. Don’t look at
the beams directly and keep your eyes at least 30cm .
away from them.
@Don’t touch the objective with fingers.
@If objective becomes dirty, playback will deteriorate.
To clean the objective, moisten a good cleaning tissue,
such as made by KODAK, in isopropyl alcohol and wipe
the objective gently. Wipe off and excess fluid with a
dry cleaning tissue.

3. Anti-shock bracket
To protect the laser pickup mechanism from shocks and
movement during transit, it is secured by a special anti
-shock bracket.
Releasing the anti-shock bracket
Before starting operation, be sure to release this bracket,
which is accessed from the bottom of the player. To do
this, place the player with its rear panel down on a firm,
smooth surface as shown in the diagram. Then insert the
lock key (metal plate) provided into the hole and turn
it to “FREE”.
Transporting the player
If the player is to be transported, the anti-shock bracket
should be fixed again. Before doing this, first open the
disc tray to make sure that a disc is not loaded. Then,
secure the anti-shock bracket by turning the screw to
“LOCK”.

VOLTAGE CONVERSION
Be sure to remove the power cord from the AC outlet
before repositioning the voltage converter switch.
1. Locate the voltage selector on the rear panel.
2. Using a flat-bladed screwdriver, set to the appropriate
230 V or 120 V position according to your area.
