(27) Adjust 1 kHz control until TI multimeter indicates 10 percent distortion. If
audio analyzer does not indicate between 8.5 and 11.5 percent distortion, perform b (8) and
(9) below.
(29) Adjust 1 kHz control until TI multimeter indicates 30 percent distortion. If
audio analyzer does not indicate between 26.5 and 33.5 percent distortion, perform b (8)
and (9) below and adjust for best in-tolerance condition.
CAUTION
Do not exceed -30 dBm input to antenna.
(30) Set 1 kHz and VAR controls to OFF.
(31) Connect signal generator to measuring receiver input.
