• While a call is not in progress, the PTT button is used to make
a new call (see Making a Radio Call on page 23).
If the Talk Permit Tone (see Turning the Talk Permit Tone On
or Off on page 61) 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
will 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. Icons for the digital features (such as
Messages) reflect this change by appearing ‘grayed out’.
Disabled features are hidden in the menu.
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.
Your radio also switches between digital and analog modes
during a dual mode scan (see Scan on page 32).
