Advanced Features in Connect Plus
Auto Fallback is a system feature that allows you to
continue to make and receive non-emergency calls
on the selected Group Contact in the event of certain
types of Connect Plus system failures.
If one of these failures occurs, your radio attempts to
roam to a different Connect Plus site. This search
process may result in your radio finding an operable
Connect Plus site, or it may result in your radio finding
a “Fallback Channel” (if your radio is enabled for Auto
Fallback). A Fallback Channel is a repeater that is
normally part of an operable Connect Plus site, but is
currently unable to communicate with either its site
controller or the Connect Plus network. In Fallback
mode, the repeater operates as a single digital
repeater. Auto Fallback Mode supports non-
emergency Group Calls only. No other call types are
supported in Fallback Mode.
Indications of Auto Fallback Mode
When your radio is using a Fallback channel, you
hear the intermittent “Fallback Tone” approximately
once every 15 seconds (except while transmitting).
The display periodically shows a brief message,
“Fallback Channel”. Your radio only permits PTT on
the selected Group Contact (Group Call, Multigroup
Call, or Site All Call). It does not allow you to make
other types of calls.
Making/Receiving Calls in Fallback Mode
Note: Calls are heard only by radios that are
monitoring the same Fallback channel and selected
to the same Group. Calls are not networked to other
sites or other repeaters.
Emergency voice calls or Emergency Alerts are not
available in Fallback mode. If you press the
emergency button in Fallback mode, the radio
provides an invalid key press tone. Display-equipped
radios also show the message, “Feature not
Private (radio to radio) and Phone calls are not
available in Fallback mode. If you attempt a call to a
private contact, you will receive a denial tone. At this
