Receiving P25 Mutual Aid calls
Calls you receive are always unencrypted group calls: any encrypted calls and
individual calls are ignored. Calls you receive may be emergency or non-
emergency, but your radio does not distinguish between them. Call reception
is simply dependent on the NAC and TGID of the call matching the values
configured for the selected channel and the selected squelch mode.
When you are receiving a call:
the tri-colour LED shows solid green (and may generate an alert if
configured)
the radio may vibrate (if configured)
the status changes to
Receiving
.
