mit on several channels, choose a frequency in the middle of the range of channels you use. (For example, if you transmit on all 40 CB channels, choose Channel 20, because it is midway between Channel 1 and Channel 40.)
•If you use a CB that has sideband modes (SSB), do not select any of these modes. (Use only AM for SWR measurements).
•If you have an amateur radio, select the continuous wave (CW) or tuning mode to check the SWR.
3.While you hold down the transmit key, rotate the meter’s knob until the needle points to CAL.
4.Release the transmit key, then set CALIBRATION/FS/SWR to SWR.
