Identifying Radio Controls

English

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.
