Advanced Radio Operations – Chapter 6
P800 User’s Manual 75
Network Operating Mode
Your P800 operates with the OpenSky Trunked
Protocol (OTP) to provide the full range of features
available on your digital voice and data network.
At the same time, if your agency cooperates with
several others in a multi-agency network supported by
OpenSky’s IP backbone, all agencies benefit from the
advantages of the network architecture whether or not
they’ve migrated from older analog equipment to
digital OpenSky radios.
Locking Out User Groups
There are at least two ways to focus your voice
communications by suppressing calls from listen
groups in your active profile.
By changing your Scanning Mode to No Scan you can
block all non-emergency voice calls from the listen
groups in your profile, concentrating your attention
entirely on your talk group.
Or, by Locking Out selected groups, you can eliminate
just the non-essential communications from being
heard on your radio. This allows you to focus on
scanning resources on just the groups whose calls you
wish to track. Lock Out will block only non-emergency
calls. Emergency Alerts and the voice calls that follow
the alerts will break through your Lock Out command.
Groups You Can Lock Out
It stands to reason that only groups in your active
profile can be locked out, since they’re the only groups
whose voice calls you’ll hear. The Lockout menu
responds to your incoming voice call activity, loading
the names of calling groups into the menu as the calls
are received.
If you don’t find a name you’re looking for in the
Lockout menu, either it’s not in your active profile, or
you haven’t received a call from that group yet in this
