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.
To calibrate the compass:
1. Press the PAGE button until the MENU Page is displayed.
2. Press the UP or DOWN button to highlight ‘Calibrate’, then press the ENTER button.
3. Press the UP or DOWN button to highlight ‘Compass’, then 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 rotat-
ing 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.

Helpful Compass Tips
1. The Electronic Compass will need to be recalibrated
outdoors every time the batteries are changed.
2. The Electronic Compass will not be accurate when used
in a car or around items that radiate a magnetic field.
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.
