GPS ALARMS
The GlobalNav II has three GPS alarms. One is an arrival alarm that

you
come within
a
preset
distance
to a
waypoint.
Another
is a cross track error alarm that sounds when
you
move off course more

The last GPS alarm is an anchor alarm that
sounds when

Initialization
-
Power On
In
order
for the
GlobalNav Ito lock onto the
satellites,
it must
first find
them. If
you simplyturn
the unit on and
wait,
the unit will find the satellites
by
itself in 15 minutes or less. This is called "Cold Start." If
you
let it find
the
satellites,
the time
display
will
probably
be
wrong,
since it will be
showing
UTC time orthetime at
Greenwich,
England.
However,
all other
navigation displays, including
the
position displaywill
be correct.
(You
can
set the time to
your
local
time.)
To
speed up
the satellite
acquisition
process, you
can initialize the GlobalNav II or "tell it where it is" the first
time it'sturned on. This initialization
process
is
usually
done
only
once and
requires
the
following
data:
1. Present
position
in
latitude/longitude
2. Elevation above sea level
(altitude)
3.
Today's
date and time

usually only
