Getting Started
Calibrating the Electronic Compass
The eTrex Summit’s Electronic Compass needs to be
calibrated outdoors after the batteries have been changed
before using the unit for navigation. Failure to calibrate
the Electronic Compass can result in gross inaccuracy of
the compass feature.
Compass Calibration:
1. Press the
PAGE
Button until the MENU Page is
displayed.
2. Using the
UP
or
DOWN
Button, highlight ‘Calibrate’
and press the
ENTER
Button.
3. Using the
UP
or
DOWN
Button, highlight ‘Compass’
and press the
ENTER
Button.
4. With ‘Start’ highlighted, press the
ENTER
Button to
begin the calibration.
5. Making sure that the unit is level, rotate the eTrex
Summit slowly two turns in the same direction. On
the display there will be a speed scale that indicates
whether you are rotating the unit ‘Too Fast’, ‘Too
Slow’ or ‘Just Right’. A message will be displayed
when the compass has been successfully calibrated.
NOTE: The eTrex Summit needs to be level
during compass calibration and use. If the unit
is tilted on either axis the compass feature will
become less accurate.

The Speed Scale indicates whether
you are ‘TOO SLOW’, ‘JUST
RIGHT’ or ‘TOO FAST’.
Helpful Compass Tips
1. The Electronic Compass will
need to be recalibrated out-
doors every time the batter-
ies are changed.
2. The Electronic Compass will
not be accurate when used in
a car or around items that
radiate a magnetic fi eld.
3. When using the compass, hold
the unit as level as possible.
The more that the unit is tilted,
the less accurate the compass
will become.
