Wide Area System Operation (Optional)

This function applies when systems are networked together in a multi-site
configuration. In this mode, calls are automatically routed to the proper system.
You may notice a delay when you press the PTT button while the system is
connecting the correct sites. The BSY indicator will be on, indicating you are
on the voice channel. In this mode, you can release and press PTT again to
override the delay. This gets you onto the system, but does not guarantee that
everyone will hear the message.
When in the multi-site mode, your radio may be programmed to look for
alternate systems when you go out of range of the currently selected system.
If an alternate system is found, the radio locks onto the system and
automatically selects the correct information for this new system. Alternately,
the radio may be programmed to revert to a conventional channel when out of
range of the trunked system.

The term system refers to the particular group of
station repeaters and set of group/special calls pro-
viding service to the radio. Radios can be prepro-
grammed to work in different systems by changing
the systems selection or through wide area roam-
ing.
A group of users share the same preprogrammed
group identification number in their radios. All
radios in the same group receive calls placed by
any one radio in the group.
A fleet of users consists of multiple groups (sub-
fleets). Radios can be preprogrammed to make
fleet calls to simultaneously access multiple user
groups.
An agency is composed of multiple fleets. Radios
can be preprogrammed to initiate agency calls to
access multiple fleets.
Every radio in the system has been assigned a
preprogrammed, unique individual identification
code. A radio can be programmed to individually
call another particular radio from the Special Call
Menu.
