Getting Started
The Getting Started Section of this manual introduces you to the basic operation of the
eTrex. eTrex features are described in more detail in the Reference Section.
The First Step
The eTrex’s GPS operates using information gathered from satellites. To initialize the unit’s
GPS receiver for the first time, take your eTrex outside and find a large, open area that has a
clear view of the sky. Press and hold the
POWER button to turn the unit on. The Welcome
Page appears for a few seconds, followed by the SkyView Page.
NOTE : When you use the eTrex for the first time, it may take up to five minutes
to find your location. After the first use, eTrex only needs about 15 to 45 seconds
to find your location.
The eTrex needs to receive at least three strong satellite signals to find your location. The
SkyView Page shows you a graphic representation of the satellites being tracked and the
strength of the satellite signals. A status message is displayed at the top of the page.
When you see the “READY TO NAVIGATE” message in the status box, eTrex has found
your location and the GPS receiver is initialized and ready for use.
Backlighting and Contrast
If lighting conditions make it hard for you to see the screen, adjust the contrast or turn on
the backlight. Press and release the POWER button from any screen to turn on the backlight.
By default, the backlight is timed to stay on for 30 seconds. To adjust the screen contrast,
press the
PAGE button until you see the SkyView Page. Press and hold the UP button to
make the screen darker; press and hold the DOWN button to make the screen lighter.
