Owner's Manual

• After the horizontal calibration, immediately begin the vertical calibration,

don ’t stop midway.

• The calibration will be effective immediately (no need to restart the aircraft).

• If the battery level gets too low or a major failure occurs, DBUS1 will

immediately initiate landing.

• If both the GPS and the optic flow and ultrasonic positioning systems

are not working, DBUS1 will start to hover until the positioning status

returns to normal or user lands it. But if the battery level gets too low

while hovering, DBUS1 will initiate landing.

• If the Wi-Fi connection is lost or the app drops out, DBUS1 will return

and land if the GPS positioning is being used, or initiate landing.

• When the app is minimized or you get a phone call, DBUS1 will start

to hover until you are back to the application. But if the battery level

gets too low while hovering, your drone will initiate landing. (We

recommend flying your drone in Airplane mode to avoid distractions).

• Please with propeller guards installed onto your drone for precaution.

Flight Protections

In order to ensure safe use and to avoid damage, we have fitted DBUS1

with multiple flight protection measures:

Connecting DBUS1 to a Mobile Device

The default SSID (Wi-Fi name) is like DBUS1-XXXXXX. Click to connect

this SSID, and input the default password: dronesbyus. You can change

them in “App Settings”. Check that the drone is connected to Wi-Fi, that

its battery level is full, and that the optic flow positioning and the GPS

positioning status are normal.

calibration goes well. Or you will need to adjust the

aircraft’s angle once again. The app will automatically

jump to the next step once it’s done.

3. Keep the aircraft head downwards vertically (the

Aircraft Status Indicator will turn solid white if it’s set to

the required angle). Slowly rotate it 2-3 times. During

this rotation, make sure the indicator stays solid white,

which means calibration goes well. Or you will need to

adjust the aircraft’s angle once again.

4.The app will notify you once the calibration is

completed. At this point, the Aircraft Status Indicator

will show the aircraft’s actual status.
