Push-To-Talk (PTT) Button
The PTT button on the side
of the radio 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 17).
If the Talk Permit Tone is enabled (see Turning the Talk Permit
Tone On or Off on page 45), 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 Selector
Knob 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.
