<span lang="en" dir="ltr">When using Windbird for the first time, or if you find that it is giving you the wrong direction, it is necessary to calibrate the Windbird :</span>

* <span lang="en" dir="ltr">Switch on Windbird</span>
* <span lang="en" dir="ltr">Press and hold the button until the LED starts flashing rapidly (approx. 10 seconds).</span>
* <span lang="en" dir="ltr">The LED flashes for 5 seconds, to give you time to prepare for calibration.</span>
* <span lang="en" dir="ltr">When the LED becomes steady, calibration begins. Rotate Windbird around its axis until the LED goes out (approx. 15 seconds). The aim is to make at least 3 turns. For the wind vane to work properly, Windbird's axis must always be as vertical as possible throughout the calibration process. The Windbird works with a compass. It may be affected by strong magnetic fields (e.g. near power lines or base stations).</span>
