Garmin Geko 301 Owner's Manual - Page 25

The Electronic Compass must be calibrated when you first use the Geko 301 and after new batteries have been installed. The accuracy of the Electronic Compass is adversely affected if the unit is not held level or by nearby items that generate magnetic fields, such as cars or buildings, etc. To Calibrate the Electronic Compass: 1. Press the PAGE Button until you arrive at the MENU Page. 2. Press the UP or DOWN Button to highlight the 'CALIBRATE' option and press the OK Button to select it. 3. With the 'COMPASS' option highlighted, press the OK Button to select it. 4. The information screen explains: "TO CALIBRATE: SLOWLY TURN TWO FULL CIRCLES IN THE SAME DIRECTION WHILE HOLDING GEKO LEVEL". *To keep level while rotating, it is recommended to place the Geko 301 on a flat surface , but not necessary. Press the OK Button to begin calibrating the compass. The unit displays a "JUST RIGHT", "TOO FAST", or "TOO SLOW" message for you to adjust your turning speed as needed. The "CALIBRATION COMPLETED SUCCESSFULLY" message displays when finished. If a "CALIBRATION FAIL" message appears, repeat the process. A 'HOLD LEVEL' reminder displays if you are not holding the Geko 301 level, or if the compass is not properly calibrated. When the compass is turned Off, the status at the top of the page displays your GPS heading, and it will stay off until you manually turn it On. When the compass in On, the status displays your compass heading. Sometimes when the compass is On, the Geko 301 bypasses the Compass and uses the GPS receiver to track your heading. The criteria for switching between the Compass and the GPS receiver is customized on the 'HEADING' Setup Page.
