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.
