EXECUTING IOP MEASUREMENT (See page 33)
[FM Tune Level Check]
Procedure:
1. Turn the power on.
2. Input the following signal from Signal Generator to FM
1. Turn the power on.
2. Input the following signal from Signal Generator to FM
antenna input directly.
* Carrier Freq : 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 tune A, B and C signals.
4. Confi rm “TUNED” is lit on the display for A, B and C
signals.
The mark of “TUNED” means “The selected station signal is
received in good condition.”
