Communication Options
Handset Operation
You use the handset to transmit and receive calls in a high noise environment or when
connected to a full duplex trunking radio station. You can transmit and receive at the same
time.
Using the Handset PTT Button
To transmit:
1. Lift the handset (off-hook).
2. Press and hold the PTT press bar in the middle of the handset. The Transmit LED
turns on while the button is pushed.
3. Speak into the mouthpiece.
4. Release the PTT press bar after you finish transmitting. The Transmit LED turns off
when the button is released.
Lifting the handset disables the internal microphone, which is the default audio transmit,
and allows you to transmit high quality audio in a full duplex mode. Always allow a short
delay after pressing the PTT button, and before speaking, to allow time for the radio chan-
nel to be established. When connected to a trunking radio station, always wait for the
grant tone before you begin to speak or your voice message may be clipped.
Note: When configuring the deskset, the installation technician has the option of disabling
the handset and/or the internal microphone.
To receive:
1. Lift the handset (off-hook).
2. Listen for receive audio in the handset ear piece.
Lifting the handset also disables the internal speaker, which is the default audio receiver,
and allows you to receive audio privately.
Enabling the Internal Speaker
You enable the internal speaker while the handset is off-hook to allow the receive audio to
be heard publicly while maintaining high quality transmit audio to the caller via the handset
mouthpiece.
Although the internal speaker and microphone are normally turned off (default) when the
handset is off-hook, you can temporarily turn the internal speaker on while the handset is
off-hook.
To turn the internal speaker on with the handset off-hook, press the Speaker button once.
The Speaker LED turns on.
To turn the internal speaker off with the handset off-hook, press the Speaker button again.
The Speaker LED turns off.
Note: Returning the handset to the cradle (on-hook) will turn the Speaker LED off.
