Selecting a Channel
FM/AM
Using Repeater Channels (FM Only)
UHF CB Repeaters are used to retransmit or relay your signal. Repeaters will extend the range of your radio and
overcome the shielding effect caused by solid obstructions. In normal Simplex operation, your radio transmits
on one particular frequency and receives on that same frequency. If there is a barrier that partially blocks your
transmitted signal, the probability of another radio receiving the signal is very slim. Hills, tall buildings, metallic
structures, ... etc. tend to act as a screen between radios.
Press the MONI button on the microphone to open the squelch and receive all
weak signals. Press and hold the MONI button for 2 seconds to hold the squelch
open. Press MONI again momentarily to cancel.
