Appendix D - Faq - Garmin eTrex Summit - Hiking GPS Receiver Owner's Manual

Why won't the eTrex Summit power on?
Check to see if the batteries are installed correctly and that the battery terminals are clean.
Can I use the eTrex Summit indoors?
Not for navigation, but you can edit existing waypoints and routes, and you can use the Demo
mode to practice (see page 51).
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 15 meters. Using differential techniques (WAAS), 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 1).
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.
What does the message "NO DGPS POSITION" mean?
eTrex Summit had a differential fix and lost it.
What do I do if it takes more than 10 minutes to get a location fix?
There may be large obstacles overhead. Move to a new location with a clear view of the sky.
See "Satellite Reception Tips" on page 62.
Why don't the eTrex Summit coordinates match the location on my map?
Make sure the unit is configured to use the same datum as your map. See pages 44–45.
