Ambient interference
– Digital compasses operate with the magnetic field of the earth. Hence
these devices react very sensitively to various ambient influences, that
distort the magnetic field of the earth, for example, when approaching
heavy metal, household devices, computers and power cables.
Never use the compass in the proximity of another compass or a
metal or magnetic object.
To obtain accurate information on the direction of movement, recali-
brate the compass (see chapter „Calibration of the device), if
1. „ERROR“ permanently appears in the display.
2. The direction details indicate an error of more than 10 degrees.
3. The device is used in a vehicle for the first time.
Calibration of the device
Press the MODE button 1 to proceed to compass mode.
Press and hold down the SELECT button 2 to proceed to calibration
mode. „CAL“ appears in the display.
Press the SELECT button once again to start the calibration. A rotating
ring appears in the display.
Rotate the device twice in a clockwise direction on a level surface that
is free from metal plates, household devices, computers, power cables
etc. Always rotate in the same direction. Ensure that you take at least
20 seconds for each rotation but not longer than one minute.
Then press the SET button 3 to complete the calibration.
Note:
If the calibration is not performed correctly, inaccurate informa-
tion could be the consequence. Perform the calibration once again if
any detail seems to be erroneous.
