TUNER SECTION
Measuring methods in confirmity with IEC standard 315
Measurements condition FM : Radio frequency = 98.1MHz, Audio frequency = 1kHz
Reference level = 1mV on ( 75ohms , 300ohms )
Deviation : MONO = +75kHz, Stereo = +67.5kHz+7.5kHz (America)
MONO = +40kHz, Stereo = +40kHz+7.5kHz (Europe)
Test Point : TP 1 = 90.1MHz, TP 2 = 98.1MHz, TP 3 = 106.1MH
Filter = B.P.F at STEREO
Power supply : 120V/60Hz (A), 220V/50Hz (C), 230V/50Hz (D/RDS)
