* Adjustment with external SWR-meter (e.g. TOS-1 PRESIDENT)
a)
To connect the SWR meter :
-
Connect the SWR meter between the CB radio and the antenna as close as
possible to the CB (use a maximum of 15.75
in
/ 40 cm cable, type President
CA 2C).

-
Bring the index needle to
by using the calibration key.
-
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 118.11
in
/ 3 m).
Your transceiver is now ready for use.
