Identifying Radio Controls

English

• While a call is not in progress, the PTT button is used to make

a new call (see Making a Radio Call on page 18).

Depending on programming, if the Talk Permit Tone or the PTT

Sidetone is enabled, wait until the short alert tone ends

before talking.

During a call, if the Channel Free Indication feature is

enabled on your radio (programmed by your dealer), you

hear a short alert tone the moment the target radio (the

radio that is receiving your call) releases the PTT button,

indicating the channel is free for you to respond.

You will also hear a continuous talk prohibit tone, if your

call is interrupted, indicating that you should release the

PTT button, for example when the radio receives an

Emergency Call.

Switching Between Conventional Analog

and Digital Mode

Each channel in your radio

can be configured as a

conventional analog or

conventional digital channel.

Use the Channel Selector

Knob to switch between an

analog or a digital channel.

When switching from digital

to analog mode, certain

features are unavailable.

Your radio also has features available in both analog and digital

mode. However, the minor differences in the way each feature

works does NOT affect the performance of your radio.

NOTE: Your radio also switches between digital and analog

modes during a dual mode scan (see Scan on

page 24).
