b)  Check the antenna connections 

c)  Turn the set on by turning the volume knob clockwise 

d)  Turn the squelch knob to minimum 

e)  Adjust the volume to a comfortable level 

f)  Go to channel 20@D band by using either the UP or DN key on the microphone or the 

rotary knob.

ADJUSTMENT OF SWR(standing wave ratio)   

 

WARNIGN:

 This must be carried out when you use your CB radio for the first time (and 

whenever you re-position your antenna). The adjustment must be carried 

out in an obstacle-free area. 

5) Adjustment with a built-in SWR meter or external SWR meter 

a)  To connect the SWR meter   

Connect the SWR meter between the CB radio and the antenna as close as possible 

to the CB radio (use a maximum of 40cm cable)   

b)  To adjust the SWR meter 

 

   

-Set the CB to channel 20@D band in FM 

-put the switch on the SWR meter to position CAL or FWD 

-Press the <<Push-To-Talk>> switch on the microphone to transmit 

-Bring the index needle to 

 by using the calibration key 

- Change the switch to position SWR (reading of the SWR level). The reading on the 

meter should be as near as possible to 1. If this is not the case, re-adjust your antenna to 

obtain a reading as close as possible to 1.( An SWR reading between 1 and 1.8 is 

acceptable). 

-It will be necessary to re-calibrate the SWR meter after each adjustment of the antenna. 

 

6) HOW TO USE INTERNAL SWR METER

 

   

-Set CB to channel 20@D band in FM 

-Press <<push-to-talk>> button on the microphone to transmit 

-At the moment, LCD would display SWR value which should be as close as possible to 1. 

If this is not the case, re-adjust your antenna to obtain a SWR value as close as possible
