point, the radio automatically keys the transmitter
(autokey) for a short period to hold the channel. The radio
sounds a mid-pitched tone when it is clear to talk; imme-
diately press the PTT button to keep the assigned chan-
nel.
Call Queued (Trunked Mode Only)
A high-pitched tone will sound and the BSY/SCN
indicator will flash green if a call request is placed in
queue after PTT activation. The receiving unit(s) also
hear(s) the tone to notify them that a call should be
received shortly. If the PTT button is released when a call
is queued, the radio will autokey whenever a channel
becomes available (see "Autokey").
System Busy (Trunked Mode Only)
Three low-pitched beeps will sound if the radio is
keyed when the system is busy, if: 1) no channels are
available for sending the message; 2) if the call queue is
full; or 3) an individual call is being attempted to a radio
that is transmitting. Release the PTT button and re-key
the radio to initiate a new channel request.
Call Denied (Trunked Mode Only)
If the radio is keyed and a low-pitched tone is heard,
then the radio is not authorized on the system that has
been selected.
