It is possible to predefine the direct mode red key call in a way that if
the radio switches to the network mode and attempts to make the
call but the service is not established within a predefined time (1-
60 seconds), the radio switches back to direct mode and always
makes the
red key call to a selected direct mode group, not to a
parametrised group.
Press and hold the red function key, and the radio attempts to make
a
red key call . Another possibility is to press the red function key
and then the back key, and the radio attempts to make a silent red
key call . However, if the silent call is made to the predefined direct
mode group, it changes into an ordinary red key call to the group.
See also Red key calls and status sending on page 25.
If a compatible direct mode gateway device is available, and a red
key call is made to a predefined direct mode group, the call may
also be transmitted to the network mode group that is predefined for
the gateway device.
If the radio receives a red key call , or a call made to a destination
that is predefined as an emergency number, the radio plays a tone,
and
Priority call is displayed with the call information.

Direct mode status messages
Your radio supports sending and receiving of status messages in
direct mode. Status messages can be sent also from a radio that is
in direct mode to a radio that is in network mode via direct mode
operation gateway. Status messages can be individual or group
addressed.
Status messages can be sent and received in idle mode. They can
also be received while receiving direct mode speech, and sent with
the AT command during transmission of direct mode speech.
