transmission level, the icon

appears on
the status line.

Menu>Networks>DMO Options

DMO Tx
Power
option if you are working in DMO on the network or the
Rep/GW
Tx Power
option if you are working in Repeater or Gateway modes.
2. Select the power level option, and press the key.
Fallback Mode
If a base station is customised to operate in fallback mode, when network
communication is lost any radios using the base station will continue to
operate, but with a reduced service. This is known as
Fallback Mode
. The base
station broadcasts the loss of communication to all radios which are using it.
In Fallback Mode your radio can only communicate with other radios that are
registered on the same site: no inter-site communication is available.
When your radio enters Fallback Mode:
the radio status bar indicates Fallback Mode and the
yellow warning
triangle is displayed momentarily
the Fallback Mode text box pops up in the centre of the screen for a few
seconds showing a customisable text message
the
RSSI antenna icon flashes continuously
the tri-colour LED flashes amber intermittently (indicating limited service
mode)
the radio generates a warning tone
When your radio leaves Fallback Mode:
the radio status bar returns to normal (Ready… or similar)
the
RSSI antenna icon stops flashing
