The GPS will attempt to get a lock anytime it has power. Remove it
from the PDA or turn off power to it when inside to avoid long lock
times later due to the GPS giving up and thinking it has to initialize
itself.
Get a position lock before driving off or entering the woods where
reception may be more difficult. The GPS can hang onto a lock
easier than it can get one.
Only one program can talk to the GPS at a time. If you have trouble
connecting to the GPS, be sure that some other program is not using
it.
Try to find a mounting position that permits angling the GPS
backward with the display pointing slightly up. This will improve the
ability of the GPS to maintain a lock.
When hiking, hold the unit horizontally with the antenna away from
you. If you put the unit in your pocket, be sure that the antenna is
faced out. The body blocks all GPS signals.
When removed from the PDA, the information in the GPS is
preserved with a supercap. Use the unit at least once a week to
keep the data intact. Otherwise expect a longer initial lock time.
Some cars have a metalized sunscreen embedded in the windshield
which blocks the GPS signals. An external antenna placed on the
outside of the car will solve this problem. Suitable locations include
the roof, the hood, the trunk area, or the top of the fenders. The
antenna lead in wire can usually be routed into the car via spaces
between the parts on the car such as within a door jamb or trunk lid.
Most external antennas have a magnet in their base to permit
attachment to the desired location. This GPS unit requires an
antenna with an MMCX connector and is designed to work on 2.5
Volts.
