Additional Laser Caution
1, Laser Interlock Mechanism
The ON/OFF (ON : low level, OFF : high level) status of the
LPS1 (S601) and LPS2 (S602) switches for detecting the
loading state is detected by the system microprocessor,
and the design prevents laser diode oscillation when both
switches LPS1 and LPS2 are not ON (low level)(clan ped
state).
Thus, interlock will no longer function if switches LPS1
(S601) and LPS2 (S602) are deliberately shorted.
Also, in the test mode *, the interlock mechanism does not
operate too.
Laser diode oscillation will continue if pins 2 and 3 of
CXA1471S (1C101) are connected to ground or pin 20 is
connected to high level (ON) or the terminals of Q10| are
shorted to each other (fault condition).
. When the cover is opened with the servo mechanism
block removed to be turned over, close viewing of the
objective lens with the naked eye will cause exposun toa
Class 1 laser beam.

¢ How to install the disc table
[7] Use nippers or other too! to cut the two sections
marked ® and the three sections marked © in
figure [1]. Then remove the spacer.
[2] While supporting the spindle motor shaft with
the stopper, pul spacer on top of yoke M, and
stick the disc table on top (takes about 9kg press-
ure). Take off the spacer.

NOTES:
@ Part without part number cannot be supplied.
@ Parts marked by“ @® ” are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable.
@ The A\ mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure
to use parts of identical designation.
@ When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits(any digit apart from 0), such as 560 ohm and 47k ohm(tolerance is shown by J=5%, and K=10%).

6. ADJUSTMENTS
6.1. Adjustment Methods
If a disc player is adjusted incorrectly or inadequately, it may malfunction or not work at all even though there is
nothing at all wrong with the pickup or the circuitry. Adjust correctly following the adjustment procedure.

@ Notes
1. Use a 10:1 probe for the oscilloscope.
2. All the knob positions (settings) for the oscilloscope in the adjustment procedures are for when a 10:1 probe is
used.
@ Test Mode
These models have a test mode so that the adjustments and checks required for service can be carried out easily.
When these models are in test mode, the keys on the front panel work differently from normal. Adjustments and
checks can be carried out by operating these keys with the correct procedure. For these models, all adjustments are
carried out in test mode.
[Setting these models to test mode]
How to set this model into test mode.
1. Turn off the power switch.
2. Press the TEST mode switch (S351). (See Figure 1.)
3. Turn on the power switch.
When the test mode is set correctly, the display is different from what it usually is when the power is turned on.
If the display is still the same as usual, test mode has not been set correctly, so repeat Steps 1 — 3.

[Release from test mode]
Here is the procedure for releasing the test mode:
1. Press the STOP key and stop all operations.
2. Turn off the power switch on the front panel.
[Operations of the keys in test mode]
Function in Test Mode Explanation
PROGRAM Focus servo close The laser diode is lit up and the focus actuator is lifted
up, then lowered slowly and the focus servo is closed at
the point where the objective lens is focused on the disc.
With the player in this state, if you lightly rotate the
stopped disc by hand, you can hear the sound the focus
servo.
If you can hear this sound, the focus servo is operating
correctly. If you press this key with no disc mounted, the
laser diode lights up, the focus actuator is pulled up, then
the actuator is lowered and raised twice and returned to
its original position.
Spindle servo ON Starts the spindle motor in the clockwise direction and
when the disc rotation reaches the prescribed speed
(about 500 rpm at the inner periphery), sets the spindle
servo in a closed loop.
Be careful. Pressing this key when there is no disc
mounted makes the spindle motor run at the maximum
speed.
If the focus servo does not go correctly into a closed loop
or the laser light shines on the mirror section at the
outermost periphery of the disc, the same sympiom is
occurred.
> PLAY/ Tracking servo Pressing this key when the focus servo and spindle servo
/O0 PAUSE close/open are operating correctly in closed loops puts the tacking
servo into a closed loop, displays the track number being
played back and the elapsed time on the front panel, and
outputs the playback signal.
If the elapsed time is not displayed or not coated
correctly or the audio is not played back correctly,it may
be that the laser is shining on the section with nosound
recorded at the outer edge of the disc, that something is
out of adjustment, or that there is some other probkm.
This key is a toggle key and open/close the tncking
servo alternately. This key has no effect if no disc is
mounted.

Explanation
Carriage reverse Moves the pickup position toward the inner diameter of
(inwards) the disc. When this key is pressed with the tracking
servo in a closed loop, the tracking servo automatically
goes into an open loop. Since the motor does not auto-
matically stop at the mechanical end point in test mode,
be careful with this operation.

The pickup and disc remain where they are when this key
is pressed.
CD magazine eject Stores Disc 1 in the CD magazine, then ejects the CD
magazine. However, even though the CD magazine is
ejected, the pickup does not return to the park position.
Even if the CD magazine is mounted again, the pickup
remains where it is.
