If necessary, to correct for the presence of ferrous metals, the compass can be calibrated. When calibrating the compass make sure to keep your motions smooth and the unit horizontal. Go to compass mode press and hold Set/ EL key till display shows “COMPASS CAL” (blinking). Continue holding Set/EL while turning the unit in a vertical position as shown. Turn the unit around twice, 15 sec per turn, as shown. After completing the 2 turns release Set/ EL key then immediately press again to confirm calibration. If the display shows “END” the calibration is successful. If the display shows “ERR” redo the calibration process.
