almost the same time), it is possible that both
radios transmit until PTT is released. In this event,
it is possible that none of the transmissions will be
understood by receiving radios.
Making calls in Fallback mode is similar to normal
functioning. Simply select the group contact you wish to
use (using the radio’s normal channel selection method),
and then press the PTT to start your call. It is possible that
the channel may be in use already by another group. If the
channel is in use, you receive a busy tone and the display
will say “Channel Busy”. You may select Group, Multi-
group or Site All Call contacts using your radio’s normal
channel selection method. While the radio is operating on
the Fallback Channel, the Multigroup operates just like
other Groups. It is only heard by radios that are currently
selected to the same Multi-group.

Returning to Normal Operation
If the site returns to normal trunking operation while you are
in range of your Fallback repeater, your radio automatically
exits Auto Fallback mode. You hear a registration "beep"
when the radio successfully registers. If you are in the
range of an operable site (that is not in Fallback mode),
you may press the Roam Request button (if programmed
for your radio) to force your radio to search for and register
on an available site. If no other site is available, your radio
returns to Auto Fallback mode after searching is complete.
If you drive out of coverage of your Fallback repeater, your
radio enters Search mode (display indicates Searching).
