Full Auto Front Loading Linear Skating Disc Loading
Mechanism ;
The disc is simply placed on the linear skating disc
table, which goes in and out horizontally, in order to
set the disc in the player. Then by pressing the PLAY
button, the disc table closes, the disc is supported by
the disc chucking mechanism and play begins.
Full-logic ‘‘Feather Touch” Operation
At the lightest touch, the “feather-touch” func-
tion buttons enable you to switch directly from one
mode to another.

Digital Readout Display
The track number and the playing time elapsed of
the selection playing is shown on the display window.
With one touch of the LAP/REMAINING TIME
button, this time display will change to indicate with
a minus sign how much playing time is left on the
disc.
Remote Control Operation
Using the supplied Remote Commander, all the
functions of the player as well as a 10-key music
select function can be remotely controlled.
Non-contact Signal Readout System
Because a laser beam is employed for signal pick-
up, there is no physical contact with the disc, which
means no wear.
In addition, because the pit pattern is recorded below
the surface of the disc, it is not necessary to be con-
stantly on guard against dust, making the disc easy to
handle.

is
Sebo
Generally, the insulation resistance of the oxide
layer in MOS IC structures is very high, and the oxide
layer is very thin. Because of this, it is possible that
the static voltages usually present on clothes and the
human body will be enough to generate a potential
difference across the insulator, high enough to cause
a breakdown of the insulating layer.
The following precautions should be taken while
handling these ICs.
(Particular care should be taken under conditions
of low humidity.)
Precautions in Replacing MOS !Cs
1. Store new ICs by inserting them into a urethane-
polyester cushion (which is somewhat conduc-
3. Equalize any potential difference between the
clothes, the tools in use, the work bench, the
set being worked on, and the packaged IC by
touching them all in succession with the hands
or a conductive wire or tool.
4. The following are effective methods for handl-
ing ICs that remove the potential difference
across the oxide layer.

@ Take a short length of fine bare wire and
wind it around the IC so that it shorts all the

5. Method of Mounting
Insert the IC while holding it with the modified
clip, and solder all the pins with the clip still
shorting the pins. (Similarly, solder all the pins
while the bare shorting wire is still wound
around them.). Remove the clip or the bare
shorting wire only after all the pins have been
soldered.
Precaution while Checking C-MOS ICs
The C-MOS ICs (Complementary MOS) are MOS
ICs that have their output sections made up of
N-channel and P-channel push-pull stages to iricrease
their speed of operation. If the output terminal of
these ICs comes into contact with B+ or B- voltage,
then the FET which is ON at that time will either
become shorted or open.
This is valid for all the output sections that are
connected together by the interconnections. Even
the circuits that are physically separated (and not on
the same board) can be destroyed simultaneously.
Example:
If this line is grounded, or touches
B+ or B- bus..., the output stage
of this IC will be destroyed.

NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as
to be focused on the disc reflective surface by the
objective lens in the optical pick-up block. Therefore,
when checking the laser diode emission, observe from
more than 30 cm away from the objective lens.
LASER DIODE CHECK
1. Ground servo amp board TP12 (IC102 pin
(LD ON)).
2. Observe the objective lens and confirm that the
laser diode is emitting light.

SECTION 1
OUTLINE
1-1.. PRECAUTIONS
- On safety
@ Check that the operating voltage of your unit is identical with the
voltage of your local power supply.
@ Should any liquid or solid object fall into the cabinet, unplug the
unit and have it checked by qualified personnel before operating
it any further.
@ Unplug the unit from the wall outlet if it is not to be used for an
extended period of time. To disconnect the cord, puil it out by
grasping the plug. Never pull the cord itself.
On installation
e@ Do not install the unit in a location near heat sources such as
radiators or air ducts, or in a place subject to direct sunlight, ex-
cessive dust, mechanical vibration or shock.
@ Good air circulation is essential to prevent internal heat build-up
in the unit. Place the unit in a location with adequate air circula-
tion. Do not place the unit on a soft surface, such as a rug that
would block the ventilation holes on the bottom.
@ The top ventilation holes must be unobstructed for the proper
operation of the unit and to prolong the life of its components.
On operation
When the unit is not used, turn the power off, to conserve energy
and to extend the useful life of your unit.
On cleaning the cabinet
Clean the cabinet, pane! and controls with a soft cloth lightly
moistened with mild detergent solution. Do not use any type of
abrasive pad, scouring powder or solvent such as alcohol or ben-
zine.
On repacking
Do not throw away the carton and the packing material. They make
an ideal container to transport the unit in. When shipping the unit
for repair work or to another tocation, repack it as illustrated on the
carton box.
NOTES ON MOISTURE CONDENSATION
‘If the player is brought directly from a cold to a warm location, or is
placed in a very damp room, moisture may condense on the lenses
inside the unit.
Should this occur, the player will not operate. In this case, remove
the disc and leave the player turned on for about an hour to
evaporate the moisture.
1-2. NOTES ON COMPACT DISCS
Handle the disc by its edge, and to keep the disc clean, do not
touch the rainbow colored surface.
Do not expose the disc to direct sunlight or heat sources such as
hot air ducts, or leave it in a car parked in direct sunlight where
there can be a considerable rise in the temperature.
4p
ee
Fue wa
RS
Pp not this way
Do not use solvents such as benzine, thinner, commercially
available cleaners or anti-static spray intended for analog discs.
After playing, store the disc in its case.
