4.1.7 Selecting Digital Talk Group
The default talk group may be set
for the channel in radio
programming. When the channel
is selected, the default talk group
is used. If a default talk group has
not been set for the channel, the
radio will use the talk group last
selected and displayed.
Each zone in the radio may have a
list of allowed talk groups. When
the radio is in digital transmit
mode, you may select a new talk
group from this list by repeatedly
pressing the (star) key until
“GROUP:” is displayed. Then use
the alpha-numeric keypad to enter
the new talk group. Then press the
left soft key (OK) to use the
entered talk group. If the entered
talk group is not in the zone’s talk group list, the radio will not allow the talk group
selection.
Each zone in the radio may have all valid talk groups assigned to it. This allows any talk
group to be selected by the by repeatedly pressing the (star) key until
“GROUP:” is displayed. Then use the alpha-numeric keypad to enter the new talk
group. Then press the left soft key (OK) to use the entered talk group.
The radio has a talk group scan feature which is on by default. When a signal is
received from any talkgroup in the list, the radio will switch to the received talkgroup for
the duration of the receive signal and then start the scan delay timer. You may reply
using the received talk group during the scan delay time, by pressing PTT. After the
scan delay time expires the radio will switch back to the selected talk group. Use MENU
| CHANNEL PARAMETERS | GROUP SCAN to turn talk group scan on/off.
