(24) Set attenuator to 0 dB, signal generator frequency to 450 MHz and amplitude
for a 0 dB TI indication.
(25) Temporarily disconnect signal generator from TI ANTENNA, press Norm (F1)
(Normalize) key, and reconnect after allowing time for normalize cycle to complete. If
necessary, adjust signal generator amplitude for a 0 dB TI indication.
(26) Repeat technique of steps (16) through (18) above. TI indications will be within
5 dB of attenuator test report values.
(27) Press key sequence listed in (a) through (g) below:
