How To Use Your Transceiver - PRESIDENT MARTIN ASC Owner's Manual

- Change the switch to position REF (reading of the SWR level). The reading on
the Meter should be as near as possible to 1. If this is not the case, readjust
your antenna to obtain a reading as close as possible to 1. (A SWR reading
between 1 and 1.8 is acceptable).
- It will be necessary to recalibrate the SWR meter after each adjustment of
the antenna.
WARNING: In order to avoid any losses and attenuations in cables used for
connection between the radio and its accessories, PRESIDENT recommends
to use a cable with a length inferior to 3 m.
Your transceiver is now ready for use.

Turn the SQ knob (2) anti-clockwise into ASC position.
No repetitive manual adjustment and a permanent improvement between
the sensitivity and the listening comfort when ASC is active. This function can
be disconnected by turning the switch clockwise. In this case the squelch
adjustment becomes manual again.
b) MANUAL SQUELCH
Turn the SQ knob (2) clockwise to the exact point where all background
noise disappears. This adjustment should be done with precision as, if set
to maximum (fully clockwise), only the strongest signals will be received.
