Signal meter should be
maximized
Distortion should be 10% or less at
each frequency.
Check to ensure that the voltage at
the ANT terminal is 54dB
µ
or less.
All signal meters should light.
All signal meter should turn OFF.
Auto reception should be avail-
able when the tuning key is moved
UP and DOWN.
See page 13 for TP locations & adjustment points.
