Owner's Manual

You’re required to calibrate your compass in the following cases:

• Before the first flight, and before the first outdoor flight;

• If the location you are flying is quite far from the last location you flew;

• The Aircraft Status Indicator shows fast purple flashing, indicating compass

failure;

• The Aircraft drifts severely, for example: cannot fly straight. Expand the

arms before calibrating so as to avoid interference.

Do not calibrate your compass near large metal objects or in places with

strong magnetic field interferences.

Do not calibrate your compass near large metal objects or in places with

strong magnetic field interferences.

Do not place DBUS1 close to other magnetic materials and electronic

devices (such as magnets, mobile phones, tablet PC and stereo equipment).

Please do not fly in areas where flying is restricted. Many areas near

airports are no-fly zones. In no-fly zones, DBUS1 will not be able to fly

while using the GPS positioning. The Aircraft Status Indicator will be

show yellow flashing. The app will alert you that you are near a no-fly

zone.

Pre-flight Checklist

1. Check if your mobile device have enough power before flying.

2. The drone’s arms are fully expanded;

3. The propellers and other parts of the aircraft are not loose or

damaged;

4.The lenses on both the optic flow camera and the front facing camera

are clean.

Calibrating the Compass

DBUS1 relies on a calibrated compass for accurate directional

functionality. The compass is easily interfered with by other magnetic

materials and electronic devices. This can lead to data inaccuracies,

and unsafe flight. On-site magnetic field conditions also affect the

accuracy of the compass. So, regular calibration before flight help the

compass to work at its best.

The process of compass calibration is as follows:

1. Expand the Arms. Turn on the aircraft. Connect to the aircraft’s Wi-Fi.

Open the Drones by US app “Settings” - “Compass Calibration”, and

tap on “Start”.

2. Keep the aircraft horizontal (the Aircraft Status Indicator will turn solid

green if it’s set to the required angle). Slowly rotate it 2-3 times. During

this rotation, make sure the indicator stays solid green, which means

No Fly Zones
