+  M  L] is pressed in this mode, the SLED 
moves to outer circumference and the message 
“SLED OUT” is displayed. 

 

When [TUNE – l m] is pressed in this mode, 
the SLED moves to inner circumference and the 
message “SLED IN” is displayed. 

[FUNCTION +]: 
 

Use this key to turn the optical pick-up laser power 
on and off. When the laser power is turned on, the 
message “LD ON” is displayed. When the laser 
power is turned off, the message “LD OFF” is dis-
played. 

CD  ERROR  CODE
The past errors of the optical pick-up system (= optical unit + CD 
board) are displayed as the BD Errors as shown below. 
Procedure:
1.  Press the [

?/1

] button to turn the power on.

2.  Press the [FUNCTION +] button to select CD function.

?/1

] simultane-

ously.

4.  Then, the BD error code is displayed as “D0xxxxxx” (x means 

hexadecimal number) on the liquid crystal display as shown 
below. 

5.  Every pressing of the [ENTER] button in this mode increments 

the number after “D” starting from “D0” up to “D4”, and then 
returns to “D0”. Every pressing of the [TUNE – l m] 
button in this mode decrements the number after “M”. The 
smaller the error code number is, the newer the error content is.

6.  To release from this mode, press the [

?/1

] button to turn the 

power off.

  It indicates the operation that is being processed when the trou-

ble has occurred.

 

It indicates the step number of each processing specifi ed by 3. 
Because the numbers of steps are different in each processing, 
this number is different in each processing. 

HCD-LX10R

Procedure:
1.  Turn on the set.
2.  Input the following signal from signal generator to FM antenna 

input directly.

Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHz
Deviation 

: 75 kHz

Modulation 

: 1 kHz

ANT input 

: 35 dBu (EMF)

Note: Use 75 ohm coaxial cable to connect signal generator and the set. 

You cannot use video cable for checking.

 

  Use signal generator whose output impedance is 75 ohm. 

3.  Set to FM tuner function and tune A, B and C signals.
4. Confi rm “TUNED” is lit on the display for A, B and C signals.

When the selected station signal is received in good condition, 
“TUNED” is displayed.

Note:
1.  CD Block is basically constructed to operate without adjustment.
2.  Use YEDS-18 disc (Part No. 3-702-101-01) unless otherwise indicat-

ed.

3.  Use an oscilloscope with more than 10 M

Ω impedance.

4.  Clean the object lens by an applicator with neutral detergent when the 

signal level is low than specifi ed value with the following checks.

5.  Check the focus bias check when optical pick-up block is replaced.

Procedure:
1.  Connect oscilloscope to TP122 (RFEQO) and TP124 (VC) on 

the CD board.

2.  Press the [

?/1

] button to turn the power on.

3.  Press the [FUNCTION +] button to select CD function.
4.  Set the disc (YEDS-18) and press the [

7

] button to playback.

5. Confi rm that oscilloscope waveform is as shown in the fi gure 

below (eye pattern).

 

A good eye pattern means that the diamond shape (

◊) in the 

center of the waveform can be clearly distinguished.
