ELECTRICAL ADJUSTMENTS

CD SECTION

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

impedance.

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

signal level is low than speci

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 TP121 (RFI) and TP124 (VC) on

the CD 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 [

] button to playback.

4. Con

rm that oscilloscope waveform is as shown in the

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 set to 98 MHz.
2. Adjust L802 so that modulation distortion may become the

best in the vicinity of the maximum value where the tuner out
level becomes –15 dBuV or more.

generator

SET

Procedure :

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. Con

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”.
