Calibration steps:
Make sure the aircraft is resting on a flat and level surface. At this
point, its 4 LEDs will transition from flashing simultaneously to
flashing clockwise. Start compass calibration.
●
If after initialization, the aircraft and watch have not paired for
some time, please restart both units.
Step 3
Compass calibration
The compass must be calibrated every time the aircraft is powered
on. The compass is susceptible to interference by other electronic
equipment, magnetic interference and metal, which can lead to
erratic behavior and loss of control. Regular calibration helps keep
the compass and its readings accurate.
2. Connect the aircraft to its battery; make sure the two are very
close to each other. Allow the watch and aircraft to pair; the watch
LEDs will stop flashing to indicate a successful pairing.
3. After the pairing is successful, aircraft and watch LEDs should be
solidly lit. While in GPS mode, the aircraft and watch LEDs flash
slowly.
