TALKING AND LISTENING

Talk Range
Your radio has been designed to maximize performance and
improve transmission range in the field. It is recommended that
you do not use the radios closer than 1.5 metres apart, to avoid
interference.
Talk range depends on the terrain. It will be affected by concrete
structures, heavy foliage and by operating radios indoors or in
vehicles.
Optimal range occurs in flat, open areas, with up to 8 kilometres
of coverage, if possible. Medium range occurs when buildings
and trees are in the way. Minimal range occurs when dense
foliage and mountains obstruct the communication path.

you transmit, to ensure that you do not interrupt other users
already on the channel.
