PROTECTION OF EYES FROM LASER BEAM DURING SERVICING -1/1

This set employs laser. Therefore, be sure to follow carefully the
instructions below when servicing.

WARNING!!

WHEN SERVICING, DO NOT APPROACH THE LASER
EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS
NECESSARY TO CONFIRM LASER BEAM EMISSION. BE
SURE TO OBSERVE FROM A DISTANCE OF MORE
THAN 30cm FROM THE SURFACE OF THE OBJECTIVE
LENS ON THE OPTICAL PICK-UP BLOCK.

Caution: Invisible laser radiation when
open and interlocks defeated avoid
exposure to beam.
Advarsel: Usynlig laserståling vedåbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsÊttelse for stråling.

VAROITUS!

Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa
mainitulla tavalla saataa altistaa käyt-täjän
turvallisuusluokan 1 ylittävälle näkymättömälle
lasersäteilylle.

VARNING!

Om apparaten används på annat sätt än vad som
specificeras i denna bruksanvising, kan användaren
utsättas för osynling laserstrålning, som överskrider
gränsen för laserklass 1.

CAUTION

Use of controls or adjustments or performance of proce­dures other than those specified herin may result in
hazardous radiation exposure.

ATTENTION

L'utillisation de commandes, réglages ou procédures autres
que ceux spécifiés peut entraîner une dangereuse
exposition aux radiations.

ADVARSEL

Usynlig laserståling ved åbning, når sikkerhedsafbrydereer
ude af funktion. Undgå udsættelse for stråling.

This Compact Disc player is classified as a CLASS 1
LASER product.
The CLASS 1 LASER PRODUCT label is located on the

Precaution to replace Optical block

(KSM-780ATA)

Body or clothes electrostatic potential could
ruin laser diode in the optical block. Be sure
ground body and workbench, and use care
the clothes do not touch the diode.

1) After the connection, remove solder shown in right figure.

SERVICE MODE -1/2

Automatic adjustment is repealed when starting TEST MODE. TEST MODE is operated after making it an initial-setting value.
A VOL+/-key becomes invalid.
It becomes invalid except the PLAY/PAUSE key at the time of an OFF display.

1. Starting Preparation and Release Method
(1) Short-circuit the short land for TEST MODE starting of MAIN C.B with solder. (Fig.1 reference)
(2) Supply a power supply and complete the preparation which starts TEST MODE.

* In TEST MODE, detection of OPEN/CLOSE SW is disregarded and always hold a CLOSE state.

(3) After TEST MODE release and TEST MODE use should surely remove the solder of a short land.

2. TEST MODE Starting
(1) TEST MODE starts by the PLAY/PAUSE key and shift to TOC lead operation.

When DISC is put in (CD-RW is unreproducible at the time of starting)
After TOC read completes, playback operation
(1 time fast playback) (Fig.2 reference)
* Other than TEST MODE 3 time fast playback.

* When the DISC is not inserted, (inserting the DISC, when reading is not possible)
Err indication (Fig.3 reference)

3. LCD all the light indications
Pushes the PLAY/PAUSE key, before being time or Err indication of playback state, the PLAY MODE key it is pushed by the fact
that the LCD all the light indications. (Fig.4 reference)

SERVICE MODE -2/2

4. ON/OFF laser change
The ON/OFF of the laser is changed to the degree which pushes the PLAY MODE key in STOP state or during Err indicating.

Fig.5 LCD indication in stop

5. Thread Sending Operation of Pickup
By the fact that it continues to push the FWD/RVS SKIP key in STOP state or during Err indicating the pickup it operates to the
inside and outside lap.
FWD SKIP key: Peripheral direction
RVS SKIP key: Inside perimeter direction

6. Focusing search mode
TOC read after the completing, length pushes the DSL key in STOP state.
Focus search operation is 1 time and observation of a S character waveform is
possible for it with an oscilloscope (IC501 23pin).
The servo gain change of the CD-DA/R and the CD-RW is effective.
As for LCD indicatory value there is no stipulation at such as amplitude value.

Fig.6 LCD indication at time of focusing search mode

7. CD-DA/R and CD-RW servo gain change
At the time of TEST MODE starting, the servo gain of CD-DA/R.
TOC read after the completing, change is possible in the degree which pushes the DSL key in STOP state. (Fig.7 reference)

Fig.7-1 CD DA/R Fig.7-2 CD-RW

8. Tracking / thread servo ON/OFF change
The ON/OFF it can point to tracking / thread servo to the degree which pushes the ENTER key in the PLAY.
