Auto Fallback
Auto Fallback is a system feature that allows you to
continue to make and receive non-emergency calls on the
selected Group Contact, if certain types of failures occur in
the Connect Plus system.
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 cannot communicate with
either the site controller or Connect Plus network at that
moment. 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.
