Figure 5 shows the already-installed Smartphone holder (figure 5, item 1). A Smartphone with a width of up
to 100 mm can be clamped here.
The holder is installed from above by pushing the holder into the attachment provided in the transmitter until it latches.
The Smartphone holder can be disassembled by pushing the entire holder out from the transmitter. Push the rear of
the transmitter above the battery compartment lid onto the grooved surface and push the holder up. The Smartphone
holder can be clipped out of the transmitter holder and removed.
11. Safety Devices
The 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 (flight 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 by an intermittent warning sound and permanent flashing
of the LED in the switch (figure 5, item 3). In this case, stop flying at once and replace the batteries of the transmitter.
b) Model
The LEDs in the quadrocopter (in the rotor outriggers) 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 LEDs flash, the quadrocopter does
not correctly receive the transmitter signal. In this case, "binding" must be performed again.
The quadrocopter constantly monitors the voltage of the integrated flight 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 the LEDs, only approx. 30 to 40 seconds
of flight time remain to independently return the model to the starting point and land it.
If a certain voltage level of the flight battery is reached, the motor control will be switched off by the transmit
-
ter and automatic landing is initiated. This process cannot be influenced by the transmitter anymore.
If the model is above a body of water, tree, house, street, persons, animals, etc. at the time and/or if the
model is flying more than 1 metre above ground, the model may be damaged or lost and there may be
property damage and injury to persons/animals nearby.
