FEATURES AND BENEFITS
13.0
Additional Decode Functions
In addition to individual and group call alerts, the functions available to be activated on successful
decode are:
13.1
Start Auto-Reset and Stop Auto-Reset (Cleardown)
The Auto Reset Timer can be started and stopped by decode of a 5 tone sequence.
Start Auto Reset decode starts the auto reset timer and opens the squelch so that voice messages
are heard. Stop Auto Reset decode (“Cleardown” or “Remote Close”) ends the auto reset timer and
returns the radio to the “Receive Squelch” so that the radio is squelched.
Start Auto-Reset and stop Auto-Reset are used to “authorise” and “de-authorise” the radio when
operating in Authorisation.
Benefits
Automatically opens squelch so that radio user can hear incoming voice message.
Automatically closes squelch, to prevent user from hearing unwanted messages.
13.2
Authorisation
Authorisation allows the central dispatch to control call set up and monitoring activity. Only
authorised radios can make calls or monitor channels. The only call a de-authorised radio can make
is the request for authorisation to a pre-determined destination.
In order that the user can be confident that their call has been received by the base, the base sends
back an acknowledgement beep for a short period. To allow the mobile user to hear the
acknowledgement beep, the “Monitor Timer” is be set to open the radio’s squelch automatically for a
few seconds.
On receipt of the request for authorisation call from the mobile, the base, when ready, sends back
an authorisation call. The mobile becomes “Authorised” when it receives this call: the squelch opens
and the PTT allows the mobile user to talk with the base.
At the end of the conversation, the radio is sent a “De-Authorisation” 5 tone sequence from the
base, to reset it back to the de-authorisation state.
It is possible for the base to authorise a whole group of radios, if “Conference Calling” is required.
Benefits
Complete control of radio usage within a team, especially useful for supervisors.
Enables central dispatcher to deal with calls on priority basis.
Enforces good system discipline.
Prevents users from listening to sensitive conversations.
Reduced time wasting leading to increased productivity.
Efficient use of air time.
