10. Safety Devices

The "Nano" quadrocopter has a range of safety devices in the transmitter and flight model which protect
the model from damage and/or should reduce possible damage to a minimum. The protection mechanisms
are identified by LED indicators (model) or an acoustic warning signal (transmitter).
a) Transmitter
The battery condition is continually inspected while the transmitter is in operation. If the voltage level of the batteries
drops below a certain value, the transmitter will signal this with a permanent flashing of the LED at the transmitter
(figure 3, item 2). In this case, stop flying at once and replace the batteries of the transmitter.
b) Model
The LEDs in the quadrocopter show if the transmitter is "bound" to the model and reception of the control signal is
proper. This is displayed by permanently lit LEDs. When the rear LEDs flash, the quadrocopter does not correctly
receive the transmitter signal. In this case, "binding" must be performed again.
The quadrotor helicopter constantly monitors the voltage of the connected battery. Should this fall below a critical level
during a particular period, this will be indicated by the flashing LEDs.
If the voltage undercut is permanently below a specific value, an emergency landing is initiated after a brief time and
the motors are switched off.
If the undervoltage is displayed at the quadrocopter by flashing of all LEDs, only a short flight time remains
to independently return the model to the starting point and land it.
If the model is above a body of water, tree, house, street, persons, animals, etc. at the time and the remain-
ing capacity of the rechargeable battery is no longer enough to return to the starting location, the model
may be damaged or lost and there may be property damage and injury to persons/animals nearby.
