Sepura SC20 series User Manual

Repeater Mode
A radio acting as a repeater provides a service to other radio users. It extends
the range and enhances the reliability of Direct Mode communication
compared with basic direct communication between radios.
You can use a repeater to enable communication between radios which are
out of range of each other. The following diagram shows radios A, B and C
and a repeater which are on the same DMO talkgroup. A, B and C are in
range of the repeater. Because of its location, the repeater can pass
communications between A, B and C even though they are out of range of
each other.
You can also use a repeater to enable communication between two radios
which cannot communicate directly, perhaps because their users are do not
have line of sight with each other.
The following diagram shows radios A and B and a repeater which are on the
same DMO talkgroup. A and B are in range of the repeater. Because of its
location, the repeater can pass communications between A and B even
though they cannot communicate directly.
