REPEATER OPERATION

Repeater operation
Repeaters allow you to extend the operational range of your
radio.
Normally, a repeater has independent frequencies for receive

■
Accessing a repeater
A repeater amplifies received signals and re-transmits them
on a different channel, allowing you to communicate over
greater distances with improved reliability. When using a

channel by 30 channels. You can search the accessible
repeater in your local area using the Repeater search scan
function (p. 13).
