Secure Communication (Encryption)
8.4.2.3
Channel with both a Talkgroup and Announcement Group Specified
For a Talkgroup Call if the override security settings feature is enabled, then the override
parameters will be used. If the override feature is not enabled, then the talkgroup
parameters will be used. If the any key option is disabled and a secure talkgroup call is
received that uses a different key than the one specified, the radio will not unmute but will
display the received call information.
parameters will be used. If the override feature is not enabled, then the talkgroup
parameters will be used. If the any key option is disabled and a secure talkgroup call is
received that uses a different key than the one specified, the radio will not unmute but will
display the received call information.
Announcement group calls ignore the talkgroup override settings. Therefore, the settings
specified on the announcement group list will be used. If the any key option is disabled
and a secure announcement group call is received that uses a different key than the one
specified, the radio will not unmute but will display the received call information.

and a secure announcement group call is received that uses a different key than the one
specified, the radio will not unmute but will display the received call information.
8.4.2.4
Channel with only an Announcement Group Specified
If a secure component talkgroup call is received, the first check will be for the any key
option as specified on the announcement group list. If the any key option is enabled, all
secure traffic (both component talkgroups and the announcement group) will unmute
provided the proper key is stored in the radio. If the any key option is disabled, then the
radio will determine the key that the talkgroup is supposed to use by reading the
programmed key PID from the talkgroup list. If the received key matches the expected
key, then the component talkgroup call will unmute. If the keys do not match, then the
radio will not unmute but will display the component talkgroup call information.

Emergency Calls on Emergency Groups
Emergency talkgroup calls will not utilize the override settings, but will be subject to the
any key rules specified above.

Scan Mode Behavior
The settings used while the radio is scanning are consistent with the modes described in
the preceding sections. Scanning mute versus unmute behavior is best illustrated with an
example.
