Q
Speaker microphone
Hold the speaker microphone approximately 10
cm (4 inches) away from your mouth when you
speak.
Important!
Do not hold the speaker microphone
near your ear, because the volume may be
extremely loud.
The speaker microphone can only be used for
one-way calls. You may have other
enhancements, such as a handsfree
microphone and a loudspeaker, available for
two-way calls.
If you receive a two-way call or make a phone
call when only the speaker microphone is
connected, the call is changed into a one-way
call. Press and hold the PTT key (1) when you speak.
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 (1 on the corner of the speaker microphone, see
Speaker microphone on page 22). 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.
