(18) Set variable attenuator from 40 to 80 dB in 10 dB steps. If TI indications are
not within 4 dB of variable attenuator test report values, perform b (12) through (33)
below.

amplitude for a 0 dB TI indication.
(21) 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.
(22) Repeat technique of steps (16) through (18) above.
