NOTE:
Be sure to connect a good earth ground to the G1'
terminal of the
FC-40
.
The carrier signal transmits continuously while
tuning is in progress. 3lease monitor the operating
freTuency before beginning the tuning process. Be
sure you are not interfering with others who may
already be using the freTuency.
It is normal to hear the sound of the relays while
tuning is in progress.
If the impedance cannot be matched by the
FC-40
better than 1, and the “
TUNER
” icon blinks, the
microprocessor will not retain the tuning data for that
freTuency, as the
FC-40
presumes that you will want
to adjust or repair your antenna system to correct the
high SW5 condition.
