The following messages are displayed while the GPS receiver is
tracking satellites:
Locating GPS Satellites
The NVE-M300 searches the sky looking for GPS satellites.
Acquiring GPS Signal
The NVE-M300 acquires positioning information transmitted
from 1 to 3 tracked satellites while searching for more satellites
(minimum 4 of needed).
Fixing GPS Position
The NVE-M300 requires continuous signals from 4 or more
tracked satellites (for 30 seconds) in order to accurately fix your
position.
Temporary Poor GPS Coverage
Thunderstorms, dense foliage or surrounding tall buildings may
cause temporary loss of position fix (acceptable if under 30
seconds).
Poor GPS Signal, Lost Position Fix
You may have entered an area where consistently poor GPS
signal (lasting 30 seconds or more) makes it impossible to
maintain a position fix.
No Line of Sight, Lost GPS Tracking
You are in an area where line of sight to GPS satellites has been
blocked.
