IMPORTANT ALARM NOTES:
Anchor Alarm – The anchor alarm may be triggered even when
you're sitting still. This can happen when using small (less than
0.05 mile) anchor alarm ranges.
Arrival Alarm – If you set the arrival alarm's distance to a small
number and run a route (see the Navigate Routes segment), this
unit may not show navigation data to the next waypoint, after you
have arrived at the first one. That will be the case if you are unable
to come close enough to the first waypoint to trip the arrival alarm.

Auto Satellite Search

To lock onto the satellites, the GPS receiver needs to know its current
position, UTC time and date. Elevation (altitude) is also used in the
equation, but it's rarely required to determine a position. It needs this
data so it can calculate which satellites should be in view. It then
searches for only those satellites.
When your GPS receiver is turned on for the first time, it doesn't know
what your position or elevation (altitude) is. The unit begins searching
for the satellites using data acquired the last time it was turned on.
This was probably at the factory. Since it's almost certain you're not at
our factory, it's probably looking for the wrong satellites.
If it doesn't find the satellites it's looking for after a short time, it
switches to Auto Search. The receiver looks for any satellite in the sky.
Due to advanced technology, the auto search time has shrunk signifi-
cantly from the early days of GPS.
Once the unit locks onto the satellites, it should take less than a minute to
find your position the next time it's turned on, provided you haven't moved
more than approximately 100 miles from the last location it was used.
