3 To select that talk group and return to normal operation, press the TG SEL switch again
or press the Select switch. If talk group selection has been disabled on the channel by
programming, the talk group does not change, “NO LIST” is displayed, and a tone
sounds.
5.15.5 P25 Unit Calls
Unit calls (also called Individual Calls) can be placed to a specific radio on Project 25
channels If the CALL option switch is programmed. Only the individual ID of the target
radio is sent (a talk group ID is not sent). The mobiles that can be called are
preprogrammed in the Unit Call list.
To receive a unit call, the RF channel of the call must be selected or scanned and the
correct NAC and unit ID must be detected. The ID of the calling radio is then transmitted
back. To respond to the call, the radio must be programmed with the CALL option switch,
and have a Unit Call programmed with the ID of the calling mobile.
Place and receive a Unit Call as follows:
1 To transmit a unit call, press the CALL option switch. The alias (tag) of the last Unit
Call is displayed.
2 If required, rotate the Select switch to display the desired call. The alias and ID of the
unit calls that have been programmed are alternately displayed.
3 Press and then release the PTT switch. Ringing is then heard and “WAIT” displayed to
indicate that the mobile is being rung. To disable this ringing but not the call, briefly
press the PTT switch again. Ringing occurs for 20 seconds or until the call is answered,
whichever occurs first.
4 When a unit ID call is received, two beeps sound (if tones are enabled), and “Call
Rcvd” and the alias of the Unit ID are alternately flashed.
5 To respond, select the Unit Call mode by pressing the CALL option key. The following
operation then occurs:
• If a unit call has been programmed with the ID of the calling mobile, it is
automatically selected. A response can then be made without changing the selected
channel.
• If no Unit Call has been programmed with the ID of the calling mobile, a response
cannot be made in this mode.
• If the call timer times out (set by programming) or the channel is changed before a
response is made, the unit call mode is exited.
