SECTION 1  
SERVICING NOTE  
When repairing this device with the power on, if you remove  
the MAIN board or open the upper panel assy, this device stops  
working.  
NOTES ON HANDLING THE OPTICAL PICK-UP  
BLOCK OR BASE UNIT  
The laser diode in the optical pick-up block may suffer electro-  
static break-down because of the potential difference generated  
by the charged electrostatic load, etc. on clothing and the human  
body.  
In this case, you can work without the device stopping by fas-  
tening the hook of the open/close detect switch (S801) with tape.  
During repair, pay attention to electrostatic break-down and also  
use the procedure in the printed matter which is included in the  
repair parts.  
The flexible board is easily damaged and should be handled with  
care.  
NOTES ON LASER DIODE EMISSION CHECK  
Never look into the laser diode emission from right avove when  
checking it for adustment. It is feared that you will lose your sight.  
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK  
(LCX-2R)  
Tape  
The laser diode in the optical pick-up block may suffer electrostatic  
break-down easily. When handling it, perform soldering bridge to  
the laser-tap on the flexible board. Also perform measures against  
electrostatic break-down sufficiently before the operation. The  
flexible board is easily damaged and should be handled with care.  
MAIN board  
S801  
This set is designed to perform automatic adjustment for each  
adjustment and write its value to EEPROM. Therefore, when  
EEPROM (IC802) has been replaced in service, be sure to per-  
form automatic adjustment and write resultant values to the new  
EEPROM.  
(Refer to page 20.)  
laser-tap  
Replacement of CXD2660R (IC502) and CXR701081 (IC801)  
used in this set requires a special tool. Therefore, they cannot be  
replaced.

TEST MODE  
2 In the normal mode, turn on the HOLD switch on the set. While  
4-1. OUTLINE  
pressing the x key on the set, press the following remote  
control keys in the following order:  
This set provides the Overall adjustment mode (Assy mode) that  
allows CD and MO disc to be automatically adjusted when in  
the test mode. In this overall adjustment mode, the protect switch  
is detected to judge the disc, CD or MO, and each adjustment is  
automatically executed in order. If a fault is found, the system  
displays its location. Also, the manual mode allows each indi-  
vidual adjustment to be automatically adjusted.  
The keys in the description refer to the keys on both set and  
remote commander unless otherwise specified. Though LCD  
display shows the LCD of the remote commander, same con-  
tents are also displayed on the LCD of the set.

4-2-2. Operation in Setting the Test Mode  
When the test mode becomes active, first the display check mode  
is selected. (Press x key once, when the display check mode  
is not active.)  
Other mode can be selected from the display check mode.  
When the test mode is set, the LCD repeats the following dis-  
play.  
4-2. TEST MODE  
4-2-1. Setting Method of Test Mode  
There are two different methods to set the test mode:  
1 Short BP801 (TEST) on the MAIN board with a solder bridge  
(connect pin y; of IC801 to the ground). Then, turn on the  
power.

For test mode set with the method 1:  
Turn off the power and open the solder bridge on BP801 (TEST)  
on the MAIN board.  
Note: Remove the solders completely. Remaining could be shorted with  
the chassis, etc.  
For test mode set with the method 2:  
Turn off the power.  
Note: If electrical adjustment (see page 20) has not been finished com-  
pletely, always start in the test mode. (The set cannot start in nor-  
mal mode.)

4-6. SELF-DIAGNOSIS DISPLAY MODE  
This set uses the self-diagnosis system in which if an error oc-  
curs in recording/playback mode, the error is detected by the  
model control and power control blocks of the microprocessor  
and information on the cause is stored as history in EEPROM.  
By viewing this history in test mode, it helps you to analyze a  
fault and determine its location.  
Total recording time has been recorded as optical pick-up using  
time, and it is compared with the total recording time in the  
self-diagnosis display mode to find when an error occurred.  
Clear both total recording time and the time in self-diagnosis  
display mode, when the optical pick-up was replaced.  
1. Setting the test mode. (See page 13)  
2. Press the MENU . key on the set or press the [DISPLAY]  
key on the remote commander activates the self-diagnosis dis-  
play mode where the LCD display as shown below.

4-6-1. Clearing Self-Diagnosis Data andTotal Recording Time  
1. Setting the test mode. (See page 13.)  
2. Move up the jog key on the set or press the [DISPLAY] key on the remote commander activates the self-diagnosis display mode.  
3. Press the X key or [REC] key on the set during display of self-diagnosis data when clearing the self-diagnosis data, or during display of  
total recording time when clearing the total recording time. Thus, ClrOK?will be displayed on the LCD, and press the same key again,  
and when self-diagnosis data is cleared ErrCLRis displayed and the data is cleared. Also when total recording time is cleared, RecT  
Ois displayed and it is cleared.

4-7. KEY CHECK MODE  
This set can check if the set and remote commander function nor-  
mally.  
Setting Method of Key Check Mode  
1. Setting the test mode. (See page 13)  
2. Press the [T MARK] or [DISPLAY] key on the remote com-  
mander for several seconds activates the key check mode where  
all segments of LCD turn OFF. (At the last two digits of DOT  
section, AD value of remote commander key line is displayed  
in hexadecimal)  
3. When each key is pressed, it is displayed on the LCD, imply-  
ing that it was successfully checked as shown below. How-  
ever, for the slide switch on the set, it is not checked unless it  
is reciprocated.  
* The key pressed to enter the key check mode was already  
checked at that time.

ELECTRICAL PARTS LIST  
MAIN  
NOTE:  
Due to standardization, replacements in  
the parts list may be different from the  
parts specified in the diagrams or the  
components used on the set.  
-XX and -X mean standardized parts, so  
they may have some difference from the  
original one.  
Items marked *are not stocked since  
they are seldom required for routine service.  
Some delay should be anticipated  
when ordering these items.  
SEMICONDUCTORS  
In each case, u : µ, for example:  
uA.. : µA.. uPA.. : µPA..  
uPB.. : µPB.. uPC.. : µPC.. uPD.. : µPD..  
Abbreviation  
The components identified by  
mark 0 or dotted line with mark  
0 are critical for safety.  
Replace only with part number  
specified.  
Les composants identifiés par une  
marque 0 sont critiques pour  
la sécurité.  
Ne les remplacer que par une piéce  
portant le numéro spécifié.  
RESISTORS  
All resistors are in ohms.  
METAL:Metal-film resistor.  
METAL OXIDE: Metal oxide-film resistor.  
F:nonflammable  
AR : Argentine model  
AUS : Australian model  
CH : Chinese model  
CAPACITORS
