Individual calls
Individual calls (point-to-point) are private calls between you and one other
person. You can make individual calls in two modes:
individual calls (half-duplex mode)—where only one person can talk at a
time using the PTT button.
individual ‘phone’ calls (full-duplex mode)—where both parties can talk
simultaneously. Use the Select/Send and Cancel/Home keys to initiate and
end the call.
During phone calls the bottom microphone (behind the keypad) and the
earpiece are active, allowing you to hold your radio against your head like
a telephone handset or a GSM telephone.
When an individual call is received, your radio sounds an audible alert and
displays the identity of the caller (if the contact is stored in your phone book)
or the ISSI of the caller.
Privacy mode
You can press a customised Privacy Mode soft key before dialling or during a
call to prevent interruptions from other calls during important or sensitive
call. When you have Privacy Mode enabled, calls made to your radio are
marked as missed calls (see Call History on page 61).
