Procedure:
1. Turn the power on.
2. Input the following signal from Signal Generator to FM
antenna input directly.
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)

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 are detected and
automatic scanning stops.

The stop of automatic scanning means “The station signal is
received in good condition.”
