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 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. Confirm that input Frequency of A, B and C detected and automatic scanning stops. The stop of automatic scanning means "The station signal is received in good condition". HCD-SH2000 13
