BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - BASIC OPERATION
Making an Emergency Call
All Selcall emergency calls are transmitted by
simultaneously pulling and twisting the on/
off switch to the Emerg. Setting and releasing
the switch. Emergency transmission will begin
immediately. The LED indicator will flash slowly
before transmission starts and become solid
green upon transmit.
An emergency call can also be initiated by press-
ing and holding the
and
keys simul-
taneously.
If the Emergency call is not enabled on the
transceiver, an error message will appear and
the emergency call will not be sent.
The action of the emergency call depends on
how the transceiver has been programmed. For
example:
•
Selective Call that transmits and automat-
ically changes to a selection of channels.
Note: Emergency Channels must be programmed using the Barrett
PRC-4090 HF SDR Programming Software (P/N BCA40001).
Transmits the emergency Selcall sequence on each of the maximum of 20
channels programmed as emergency channels. There is a pause between
calls allowing the operator to listen for an acknowledgment coming back.
After the Emergency call is attempted on all the preprogrammed emer-
gency channels the transceiver will go back into scan mode (if scanning is
available) or stay on the last channel selected before the Emergency call
was initiated.
If a GPS receiver is fitted and enabled, the GPS position is also sent with
the call.
Note: After the emergency call has been sent, there is no indication that a call
has been sent for security purposes.
