8.1 AM/FM RF ADJUSTMENT
1. Signal input must be as low as possible to avoid overload and clipping. (Use highest sensitivity of output indicator).
2. Balance and tone controls at mechanical center.
3. Standard modulation is 400 Hz at 30% amplitude for AM. 1000 Hz at 75 kHz deviation for FM.
4. Connect 4 ohm load across speaker jack.
