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 meters 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.
