Voice Calls
As soon as your radio completes the startup sequence and
is live on the OpenSky network, you’ll begin to hear voice
calls from the talk and listen groups in your active profile.
No action is required on your part, but the following list
details how your radio responds to incoming voice
messages.
 Initial Network Registration
1.) If the radio has never been registered on your
network, it will attempt to use a default User ID, if
one is available.
2.) If the radio has been previously registered on the
network, it will automatically attempt to re-register
with the same User ID and Password as previously
used. Once registered, the Default Profile Name will
be shown on the display panel.
3.) If registration fails, the message NOT REG will flash
on the display.
