BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - SELCALL

When a transceiver receives a beacon request call, it responds by transmitting
the Beacon Call revertive tones. No indications occur on the transceiver. Beacon
Calls are not saved in the Selcall History.

Sending a Selcall

-
fic is not heard, continue.

and, if necessary, press the
icon to show the Call Selection
screen.

ually and press Enter, or
• Choose a contact from the Contacts

and then select Selcall.
5. Wait for the Selcall to be sent and listen for the revertive signal that indi-

•
If a revertive tone is not heard or was difficult to hear, try another
channel and repeat the process until a good channel is found.
• If a revertive tone is heard but you receive no verbal response from
the station, it may be because the Operator is unavailable at the time.
