8. Operation, flight calibration and settings
a) Charging the flight battery
First, remove the battery from the drone. Release the plug contact to the board and pull the battery out of the retaining
flaps on the loop.
Do not pull on the cable to remove the battery from the drone.
Connect the flight battery to the USB charging adapter and insert this into a type A USB (5 V DC) port. This may be
an output on a computer, a small device charger or power bank.
The plug is equipped with mechanical polarity protection. It can only be connected in a certain position.
Never use force to make the connection. Instead, change the orientation of the plug, if necessary.
The charging process takes approx. 60 minutes (fully drained -> fully charged). As soon as the red charging LED on
the adapter goes out, the battery is ready for flight.
The LEDs on the drone flash as soon as the battery is drained.
Land the quadrocopter safely and charge the battery.
b) Setting the correct flight frequency
For flight operation, you can switch between different radio frequencies. This allows several identical drones to be
flown at the same time, independently of one another.
The LEDs flash quickly after connecting the flight battery to the drone. Switch the remote control on and push the left
joystick all the way up and then all the way down. When the remote control emits an acoustic signal, frequency setting
is complete. The LEDs light up uniformly.
