is referenced to 1 kHz, compressor enabled. (This is an optional test that re-
quires a distortion analyzer).
5.3.2.F. Audio Response:
350 Hz = ___NMT 6dB down 1 kHz = ___ 0dB 2.5 kHz = ___NMT 6dB down
Input a 100 uV standard audio test signal into the unit. Disable the audio com-
pressor by grounding pin 10 on P96A1, P97A1. Monitor the receiver output.
5.3.2.G. Compressor: ___/- 3 dB
Input a 100 uV standard audio test signal into the unit. Vary the modulation
