ELECTRICAL CHECK
Procedure:
1. Turn the power on.
2. Input the following signal from Signal Generator to FM
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

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
