REPEATER OPERATION

■ Repeater operation
Repeaters extend the operational range of the transceiver
by retransmitting the received signals. They are usually
located on the top of a building or a mountain, as the
elevation increases their effectiveness, allowing the user
to transmit and receive over greater distances. During
a standard operation, or simplex, transceivers transmit
and receive on the same frequency. When operating
in the Duplex mode (example: accessing a repeater),
the transceiver will transmit and receive on different
frequencies. It automatically does this when one of the
repeater channels is selected.

D Accessing a repeater
A repeater amplifies received signals, and retransmits them
on a different frequency, allowing you to communicate
over greater distances with improved reliability. To use a
repeater, a repeater channel must be selected (Repeater
CH 1 to 8, and 41 to 48).
You can search the accessible repeater in your local area
using the Repeater search scan function. (p. 25)
