Hands-free mode
If you are using a full-duplex audio accessory, simply press the Select/Send
key and continue fully hands free.
Receiving a phone call
When an incoming phone call is received, your radio sounds an audible alert
and displays the identity of the caller (if the contact or number is stored in
your phone book).
1. Press the Accept context key or the Select/Send key to answer the call.
Press the Reject context key or the Cancel/Home key to reject the call.
2. To end the call, press the Clear context key or the Cancel/Home key.
Note: Your radio can be customised to answer calls automatically after a
set time period, exactly as if the Accept context key or the Select/Send key
had been pressed. If the time period is set to zero the call may be
answered before any alerts are audible.
Answering phone calls in half-duplex mode
You can answer an incoming full-duplex (phone) call as a half-duplex call.
This is useful, for example, where a full-duplex call could pick up too much
background noise for clear communications.
1. Press the PTT button to answer the call in half-duplex mode.
2. Continue as for Group calls and individual half-duplex calls:
To speak press and hold the PTT button and speak into the
microphone.
To listen release the PTT button and listen to audio received through
the speaker.
3. To end the call, press the Clear context key or the Cancel/Home key.
Broadcast calls
Sometimes it may be necessary for your Dispatcher to make a high-priority
broadcast (also known as a Site Wide Call) to all network users. These calls
take priority over any lower priority on-going calls, and you cannot respond
to them: pressing the PTT key has no effect during a broadcast call.
