Initiating or Answering a Radio Channel Transmission
The deskset is always in receive mode unless you press the
PTT
,
Transmit
or
Intercom
buttons. When the handset is on-hook, the deskset mouthpiece continuously routes all
radio communication and intercom audio to the internal speaker. Alternately, if you lift the
handset (off-hook) the audio is heard via the handset ear piece.
To visually verify that you can initiate or answer a radio channel transmission, look at the
Busy
LED. If the
Busy
LED is on, a parallel deskset is being used and you cannot trans-
mit until the
Busy
LED is off.
The deskset can be connected to a radio configured for a conventional or trunked radio
system. A conventional system uses discrete frequencies. A trunked system selects a free
radio channel automatically and notifies you with an audible grant tone when a free radio
channel is found.
For a conventional system you use the
Mode Up
or
Mode Down
buttons to select a radio
channel and its associated TX/RX frequency/ies that you wish to monitor or on which to
transmit or receive. Only one radio channel can be selected at a time.
Note:
The procedure for paging or making a Stat Alert page from a conventional radio
versus a trunked radio differ. Please refer to the specific digital radio’s user documen-
tation for specific instructions.
Note:
The procedure for making a telephone call from a conventional radio versus a
trunked radio differ. Please refer to the specific digital radio’s user documentation for
specific instructions.
