the Electronic Compass can result in gross inaccuracy of
the compass feature.

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.
