Frequently Asked Questions
Frequently Asked Questions
Time Format and re-select the time format you are using unless
you are using UTC. After selecting the format you will be given
the opportunity to change the time.
How long can I expect my MAP 330 to run on a fresh set of batteries?
Under normal operating conditions you should get up to 10
hours of use while the display backlight is turned off. This
duration will drop significantly if you use the display backlight.
How often do I need to initialize the MAP 330?
Initializing the MAP 330 decreases the time it takes to get a
position fix during cold start. What is meant by a cold start is
that the MAP 330 has no reference to use as a guide to tell it
what satellites should be overhead. Without a reference to start
with, the MAP 330 will have to “search the sky” trying to find
any satellite that may be in “view.” This takes time and can
increase the time it takes to get its first position fix. (Can take
10 minutes in severe conditions.)
So where does this reference come from? Under normal
operating conditions, the last position fix computed before the
MAP 330 was turned off is stored into memory and will be used
as the reference the next time the MAP 330 is turned on.
However, if you cleared the memory (see Clearing Memory - All
in the Reference Chapter) this stored reference point is removed
from memory and you probably will want to initialize the
receiver again. Also, if you travel with your MAP 330 for more
than 500 miles with it turned off, it will still have the reference
point but it may be too inaccurate to be useful and again, you
may want to initialize the MAP 330.
Waypoints/Database
What waypoints come preloaded on my MAP 330’s database?
The Database contains cities, highways, airports, waterways and
national parks.
