Each time a button is pressed, “K” value increases. However, 
once  a  button  has  been  pressed,  it  is  no  longer  taken  into 
account.

 

“V” value increases in the manner of 0, 1, 2, 3 ... if [MASTER 
VOLUME] knob is turned clockwise, or it decreases in the 
manner of 0, 9, 8, 7 ... if [MASTER VOLUME] knob is turned 
counterclockwise.

8. When [] button is pressed after all LEDs and segments in 

liquid crystal display light up, alternate segments in liquid 
crystal display and LEDs would light up. If you press [] 
button  again,  another  half  of  alternate  segments  in  liquid 
crystal display and LEDs would light up. Pressing [] button 
again would cause all segments in liquid crystal display and 
LEDs light up. Pressing [] button again would turn off all 
segments in fl uorescent indicator tube and all LEDs.

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 MΩ 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 the oscilloscope to CN507 pin 6 (RFMON) and
 

CN507 pin 3 (GND) on the MB board.

2.  Press the [

?/1

] button to turn the power on, and press the 

[FUNCTION] button to select CD function.

3.  Set disc (YEDS-18) and press the [u] button to playback.
4. 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.

1.  Turn the power on.
2.  Input the following signal from Signal Generator to FM an-

tenna 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: Please use 75 ohm “coaxial cable” to connect SG and the set. You 

cannot use video cable for checking.

 

  Please use SG whose output impedance is 75 ohm.

3.  Set to FM tuner function and scan the input FM signal with 

automatic scanning.

4. Confi rm that input Frequency of A, B and C detected and auto-

matic scanning stops.

The stop of automatic scanning means “The station signal is re-
ceived in good condition”.
