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).
