Push-To-Talk (PTT) Button
The PTT button on the side
of the microphone serves
two basic purposes:
• While a call is in
progress, the PTT button
allows the radio to
transmit to other radios in
the call.
Press and hold down PTT
button to talk. Release
the PTT button to listen.
The microphone is activated when the PTT button is pressed.
• While a call is not in progress, the PTT button is used to make
a new call (see Making a Radio Call on page 13).
If the Talk Permit Tone is enabled (see Turning the Talk
Permit Tone On or Off on page 37), wait until the short alert
tone ends before talking.
Switching Between Conventional and
Trunking Mode
Each channel in your
radio can be configured
as a conventional channel
or a trunking channel. Use
the Channel Rocker to
switch between a
conventional or a trunking
channel.
When switching from trunking to conventional mode, certain
features are unavailable. Icons for the trunking features reflect
this change by appearing “grayed out’. Disabled features are
hidden in the menu.
Your radio also has features available in both conventional and
trunking mode. However, the minor differences in the way each
feature works does NOT affect the performance of your radio.
