ONE-TOUCH KEY FUNCTIONS
LOCK/UNLOCK TALK GROUP
This is a soft key (Up-arrow - SK3) option used to initiate the talk group
lock feature. The feature enables you to remain locked to a specific talk group
tag position in an idle state regardless of activity from other downloaded talk
groups (subject to Network Monitor Codes).
1. When the handset is powered up and then goes into Idle State, SK3 is
the LOCK key. This indicates that the talk group feature is unlocked and
that pressing SK3 will initiate the lock.
2. To lock the specific talk group, press SK3. The SK3 indicator then
changes to UNLOCK, and
appears at the top of the display.
3. To unlock the specific talk group, press SK3. The SK3 indicator then
changes back to LOCK, and the
icon disappears.
GPS ON/OFF
When you are in a Dispatch Radio call, SK1 toggles the display of GPS
position.
1. If GPS information is currently displayed, press SK1 to suppress the
display. The GPS display is then erased.
2. If the GPS information is not currently displayed, press SK1 to restore
the display.
PTT OPERATION
1. To initiate a Dispatch Radio call, press and hold the PTT key. The
CALLING and IN USE indicators then appear in the display followed by
USER ON, and an audible tone is emitted, indicating that you are the
current speaker.
2. When you release the PTT key, the VACANT indicator is displayed on
the handset, informing you that the channel is open to other talk group
members. If there is no response after a period of time, the talk group will
be dropped from the network. Control then reverts back to the idle
Dispatch Radio screen display.
