Can I use the eTrex Summit indoors?
No. The DEMO mode is available, but we suggest that 
only dealers use it.
Do I need to subscribe to a service to use the 
eTrex Summit?
No. The GPS satellites are owned by the United States 
Department of Defense (DoD) and have been funded by 
U.S. taxpayers’ dollars.  Reception of GPS satellite signals 
is free to everyone.
Does the eTrex Summit work anywhere in the world and 
in any weather?
Yes.
How accurate is a GARMIN GPS?
The eTrex Summit is accurate to within 100 meters under 
the DoD-imposed Selective Availability (S/A).  Without 
S/A, the eTrex Summit is accurate to within 15 meters.  
Using differential techniques, the eTrex Summit can be 
as accurate as 1-5 meters.
Why can’t I see the display in the daylight?
Adjust the contrast (see page 9).  
Why can’t I interface my computer with the eTrex Summit?
Make sure that you have the correct INPUT/OUTPUT 
format selected on your eTrex Summit.
