Frequently Asked Questions How long can I expect my Meridian to run on a fresh set of batteries? Under normal operating conditions you should get up to 14 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 Meridian? Initializing the Meridian decreases the time it takes to get a position fix during cold start. What is meant by a cold start is that the Meridian has no reference to use as a guide to tell it what satellites should be overhead. Without a reference to start with, the Meridian 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 Meridian was turned off is stored into memory and will be used as the reference the next time the Meridian 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 Meridian 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 Meridian. Waypoints/Database What waypoints come preloaded on my Meridian's database? The Database contains cities, highways, airports, waterways and national parks. Can I delete preloaded waypoints that I don't use? No. Waypoints that are preloaded into the Meridian will always be available, even when all of the Meridian's memory has been cleared.

Frequently Asked Questions
How long can I expect my Meridian to run on a fresh set of batteries?
Under normal operating conditions you should get up to 14
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 Meridian?
Initializing the Meridian decreases the time it takes to get a
position fix during cold start.
What is meant by a cold start is
that the Meridian has no reference to use as a guide to tell it
what satellites should be overhead.
Without a reference to start
with, the Meridian 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
Meridian was turned off is stored into memory and will be used
as the reference the next time the Meridian 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 Meridian 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 Meridian.
Waypoints/Database
What waypoints come preloaded on my Meridian’s database?
The Database contains cities, highways, airports, waterways and
national parks.
Can I delete preloaded waypoints that I don’t use?
No.
Waypoints that are preloaded into the Meridian will always
be available, even when all of the Meridian’s memory has been
cleared.
