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 Voice Call on page 12).
If the Talk Permit Tone is enabled (see Turning the Talk
Permit Tone On or Off on page 42), wait until the short
alert tone ends before talking.
Switching Between Analog and Digital
Mode
Each channel in your
radio can be
configured as an
analog channel or a
digital channel. Use
the Channel Rocker
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.
NOTE: Your radio also switches between digital and analog
modes during a dual mode scan (see Scan on
page 20).
