1. CD Block is basically designed to operate without
adjustment. Therefore, check each item in order given.
2. Use YEDS-18 (Part No. 3-702-101-01) unless otherwise
indicated.
3. Use an oscilloscope with more than 10M
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.

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

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.
