Q
PTT (Push-to-talk) key
Your radio can make and receive one-way and two-way calls.
During a one-way call, only one person can speak at a time,
and the speaker must press and hold the PTT key. During a
two-way call, the PTT key is not used, and you can speak as in
a conventional phone call.
To speak during a one-way call, press and hold the PTT key.
You can start speaking after a short tone is played and
(transmitting) appears on the display. Release the PTT key to
let the other party speak. (receiving) is displayed when you
receive a one-way call.
Express calls and group calls are one-way calls. Phone calls
are normally two-way calls, but your radio is also capable of
making and receiving one-way phone calls. The network
changes the call type if needed.
For group calls in the network mode, you can set the PTT key to make a call
either always to your selected talk group, or to the talk group whose name is
on the display (either the active scanned group or the selected group). See
PTT key settings on page 40.
Q
H/L key (or duty key)
H/L key to activate/deactivate the loudspeaker
Your radio has a high volume loudspeaker (1) for
hands-free use. When the loudspeaker is in use,
is displayed, and you can listen and speak to the
radio from a short distance.
Warning:
Do not hold the radio near your ear
when the loudspeaker is in use, because the volume may be extremely loud.
