PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
VAROITUS!
Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa mainit-
ulla tavalla saattaa altistaa käyt-täjän turvallisuusluokan 1 ylit-
tävälle 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: Invisible laser radiation when
open and interlocks defeated avoid expo-
sure to beam.
Advarsel:Usynling laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
ATTENTION
L'utilisation 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 rear
exterior.
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.

Precaution to replace Optical block
(KSS-213F)
1) After the connection, remove solder shown in
the right figure.
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. How to replace PICK UP.
1) Open the TRAY.
Push the stopper to arrow direction and release half of
the SHAFT SLED.
2) Turn GEAR MAIN CAM to the counterclockwise
(arrow “a”) direction, and lift up CD mechanism. (Fig-1)
3) Remove SHAFT SLED.
4) CD mechanism in down position, replace PICK UP.
5) Lift up CD mechanism (Fig-1), and Reassemble the
SHAFT SLED.
2. How to remove the 5CD CHANGER BLOCK
(Fig-2)
1) Remove the two FFC of the CD circuit board, and
remove the five SCREWS.
2) Lift 5 CD CHANGER BLOCK from behind, and
remove it. (5CD CHANGER BLOCK can be removed
even if PANEL TRAY is not removed.)

3. The disassemble and reassemble the TRAY
3-1. Disassembling procedure.
1) Push the PLATE GEAR’S Boss at the bottom part of
CHAS MECHA strongly to the outside (arrow “b”
direction). (Fig-3)
(Confirm that TRAY appears a little in the front.)
2) Draw TRAY to the open position.
3) Remove FFC, and push the two LEVERS at both side of
the CHAS MECH to remove TRAY. (Fig-4)
3-2. Reassembling procedure.
1) Confirm that LEVER TRAY is at the most right position
and check for the CD Mechanism to be in the down
position. (Fig-5)
2) Push in the TRAY along the rail of the CHAS MECHA.

4. How to reassemble the TURN TABLE. (Fig-7)
1) Push LEVER TT in the direction of “C”, and put in the
TURN TABLE 5CD. (Fig-7)
After reassembly, one of the TURN TABLE DISC
TRAY (can be either one of the five disc trays) must be
aligned with TURN TABLE 5CD. (Fig-8)
That is, having no gap difference between the TURN
TABLE 5CD and the TRAY 5CD.
* When reassembling the TURN TABLE 5CD, it is
acceptable facing any CD number (1-5).

GFS output, MNT3 or XRAOF output by switching command.
C2PO output, GTOP output by switching command.
X’tal select input terminal, X’tal: 16.9344MHz = “L” 33.8688MHz = “H”.
4.2336MHz output, Output 1/4 divided frequency of VCKI at CAV-W mode.
Digital Out connector output signal.
“H” when the playback disc has emphasis. “L” when it does not.
De-emphasis ON/OFF, “H” when ON, “L” when OFF.
WFCK output.

Reset system at “L” setting.
Note) • PCMD is the two’s complement output with MSB first.
• GTOP monitors the protection status of the Frame Sync. (H: Sync protection window opened).
• XUGF is the Frame Sync negative pulse which is obtained from the EFM signal. This is the signal before the sync protection.
• XPLCK is the inverted signal of the EFM PLL clock. The PLL works so that the fall-down edge and the changed point of the
EFM signal agree.
• GFS is the signal that goes “H” when the Frame Sync and the internally inserted timing agree.
• RFCK is the signal having 136 micro-seconds (during normal speed) that is generated to have the same accuracy as X’tal.
• C2PO is the signal indicating the error status of the data.
• XRAOF is the signal that is generated when the 16k RAM goes outside the jitter margin ±4F.

[Play mode]
Lighting of all displays of the FL tubes are turned off and
returns to normal display. The focus search (numbers of
search is unlimited) is performed. When focus comes to
in-focus, the focus servo is locked in and the machines
enters the normal play mode.
During [Play mode], GFS and sound skipping are not
monitored.
When focus becomes out-of-focus, another attempt is
made to search for focus.
The tracking servo and the sled servo can be turned on
and off by pressing the [ ] key.
Pressing the [ ] key establishes the [Sled mode].
The [ ] display can be turned on and off by pressing
the [ ] key .
While the [ ] display is turned off:
CLV-A Tracking servo: on
Sled servo: on
While the [ ] display is turned on:
CLV-A Tracking servo: off
Sled servo: off
Pressing the [ ] key decreases the track number to -1.
Pressing the [ ] key increases the track number to +1.
Pressing OPEN/CLOSE key opens or closes the tray.
The machine enters the [Sled mode].
< How to Exit the Test Mode >
Remove the AC power cord from power outlet, or turn
off the system power.
< How to Enter the Test Mode >
Note: Target models of this test mode.
CX-ZR550
CX-ZVR55
While pressing the CD key, insert the AC power cord to
AC wall outlet.
< When the Machine Has Entered the Test
Mode >
The system is initialized and the main power is turned on.
During the test mode, the main power of the CD block is
turned on always. The test mode starts with the [Sled
mode].
< Types of Test Mode >
[Sled mode]
All displays of the FL tubes light. The optical pickup can
be moved by pressing [ ] or [ ] key.
Pressing the[ ] key establishes the [Focus mode].
Pressing the [ ] key establishes the [Play mode].
Pressing the [ ] key moves the sled to outer
circumference.
Pressing the [ ] key moves the sled to inner
circumference.
Pressing OPEN/CLOSE key opens or closes the tray.
[Focus mode]
Lighting of all displays of the FL tubes are turned off and
returns to normal display. The focus search is performed
in the focus mode regardless whether disc is inserted or
not, or focus OK or NG. (Numbers of times of focus
search is unlimited. Auto sequence is not used.)
Focus servo is not locked in even the focus is obtained.
Pressing the [ ] key establishes the [Play mode].
Pressing the [ ] key decreases the track number to -1.
Pressing the [ ] key increases the track number to +1.
Pressing OPEN/CLOSE key opens or closes the tray.
The machine enters the [Sled mode].
