Trunking Mode Operation
Talk Group Selection
1. Up/Down Select- Press the Up/Down key (▲ or ▼ ) to display the
desired talk group. An up-select or down-select tone sounds with
each change. If you press and hold either key, the radio changes
talk groups rapidly.
(If programmed with a "stop", talk
group changes will stop when the
highest or lowest talk group number
has been reached.)
2. A/B Key Selection - Either or both of the A and B keys may be
programmed for instant selection of a pre-programmed talk group.
Press the programmed key to instantly select the programmed talk
group.
3. Direct Talk group Selection - The numeric keypad 0-9 keys may
be used to directly select the desired talk group. Press one or two
digits and the Up-select key (▲) to select a talk group. For
example, press 4, 7 and (▲) to select talk group 47. If the (▲) key
is not pressed within 5 seconds after pressing the digit keys, the
entered digits will be ignored. During the 5 second period, the (▼)
key may be used to clear the entered digits from the display.
4. Direct System Selection - The numeric keypad 0-9 keys may be
alternatively programmed to make system selections instead of talk
group selections. If programmed for such operation, the lowest
numbered talk group in the selected system will be displayed. Use
the Up- or Down-select keys to select the desired talk group within
the system.

Scan Lock Out
Individual talk groups or complete systems can be locked out of the
scan list at any time.
• Talk Group Lock Out - press and release the L/O key to
lock out the currently selected talk group. The L/O icon will
be displayed to indicate the lockout condition. Press and
release the L/O key again to restore the selected talk group
to the scan list.
• System Lock Out - press and hold the L/O key for 2 seconds
on any talk group in the system. The L/O icon will blink when
any talk group in that system is selected, regardless of whether
that group has been individually locked out. Press and release
the L/O key on any talk group in a locked out system to
restore the system to the scan list.
Revert Operation
During scan operation, the active talk group selection may change
depending on the revert programming.
• Last Talk Group Revert - the received talk group becomes the
active talk group.
• Talkback Revert - the received talk group becomes the active
talk group only if the PTT is pressed during the dropout delay
time (period before scan resumes).
• No Revert - the selected talk group is always active regardless
of what other talk groups are received. To answer a call on
another talk group, use the Up- or Down-select keys to display
the received talk group, then press the PTT.
