Note: If a radio is within range of a repeater but for some reason a call
cannot be set up through it your radio attempts to set up the call in DMO
Mode and the Communication Mismatch icon is displayed to all
members of the talkgroup to indicate that there may be members of the
talkgroup who cannot take part in the call.
DMO options
You can select the following DMO options:
Presence Check
Specify whether Presence Checking is performed before DMO Individual
calls are made. When Presence Checking is On your radio checks whether the
intended receiving radio is available and in radio contact before it attempts to
set up the call.
GW/Rep Filter
Specify whether your radio uses or ignores any gateway and/or repeater it
detects.
In the Gateway/Repeater Filter screen select one of the following options:
No GW/Rep—do not use any gateways and repeaters detected by your
radio
Use Repeater—Use repeaters detected
Use Gateway—Use gateways detected
Use GW/Rep—Use a gateway or a repeater detected by your radio.
Note: When option Use GW/Rep is selected, your radio selects the first
gateway or repeater that it detects. If it selects a gateway, a gateway
icon is displayed on the status line. If the gateway stops sending a
presence signal it will no longer be detected by your radio which may
then detect a repeater. In this case the gateway icon is replaced by the
repeater icon on the status line.
Therefore when you are making a call look at the display to understand
how it will be made. Take care if a repeater and a gateway are using the
same frequency and your radio is configured to use both devices (that is,
option Use GW/Rep is selected).
