A
DVICE
:
We recommend that you connect a dummy load
to one of the
$
ntenna jacks, and monitor your
signal on a separate receiver, to prevent interfer-
ence to other users.
You will have the best chance of hearing the ef-
fects of adjustments if you wear headphones
connected to the monitor receiver) while listen-
ing to your transmitted signal.
