Calibrate for SWR (Standing Wave Ratio)
SWR calibration is done to properly adjust the length of the antenna and to monitor the
quality of the coaxial cable and all RF connections.
This calibration is critical in order to achieve optimum performance.

5. Release the PTT button, press and
release the S/RF-SWR CAL button to the
SWR position. Then press the PTT button
to read the SWR reading.
6. Repeat the same steps two through five
on Channel 1 and 40. This will check
SWR for all channels.
To Receive
Rotate the On/Off Volume knob clockwise.
The RX icon will be displayed.
Selecting a Channel
Unit should be in CB mode. Rotate channel
selector clockwide or counter-clockwise to
select desired channel.
S-Meter
Swings proportionately to strength of
incoming signal when receiving.
The S/RF-SWR-CAL switch must be in the
S/RF setting to read the meter.
