Important!

When using the watch compass for serious trekking or climbing, always take along another compass to confirm readings. If the readings produced by the Digital Compass of this watch are different from those of the other compass, perform figure eight calibration or bidirectional calibration of the watch compass to ensure better accuracy.
Direction readings and calibration will not be possible if the watch is near a permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or electrical appliances (TV, computer, cellphone, etc.)
The Altimeter Mode displays relative altitude based on barometric pressure readings. Readings taken at different times at the same location may produce different values due to changes in pressure. The value displayed by the watch may be different from the actual elevation and/or sea level elevation of your location.
When using the Altimeter Mode for mountain climbing or other activities, it is highly recommended that you check a map, local altitude indications, or some other source for your current correct altitude, and that you regularly calibrate the Altimeter Mode.
Calibration: Operation Guide available at the CASIO website.
