Accessing the Programmed Functions
You can access various radio functions through one of the
following ways:
• A short or long press of the
relevant programmable buttons.
OR
• Use the Menu Navigation Buttons as follows:
1 To access the menu, press the S button. Press the
appropriate Menu Scroll button ( P or Q ) to access
the menu functions.
2 To select a function or enter a sub-menu, press the N
button.
3 To go back one menu level, or to return to the previous
screen, press the
R button. Long press the R button
to return to the Home screen.
The Menu Navigation Buttons are also available on a keypad
microphone (see Using the Keypad on page 64).
NOTE: Your radio automatically exits the menu after a period
of inactivity and returns to your Home screen.
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 16).
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.
