b) Before operation
• Always turn the transmitter on first and then connect the helicopter's flight battery right away to the receiver/control
unit. This is the only way to perform a frequency match (binding function) between the transmitter and the receiver
and ensure that your model reacts reliably to the control commands of the transmitter.
• Check the function safety of your model and of the remote control system. Pay attention to visible damages such as
broken plug-in connections or damaged cables. All movable parts on the model have to be smooth running; however,
there must be no tolerance in the bearing.
• Charge the flight battery, which is necessary for operation, as well as the rechargeable battery needed in the remote
control according the instructions indicated by the manufacturer.
• As power source for the plug-in mains unit, use a 230V/50 Hz mains socket of the public mains only. Never try to
operate the device at another voltage.
• If batteries are used for the power supply of the transmitter, make sure that there is a sufficient rest capacity (battery
checker). If the batteries are empty, always replace the complete set, never individual cells only.
• Before each operation, control the settings of the trim slider at the transmitter for different steering directions and, if
necessary, set them.
c) During operation
• Do not take any risks when operating the product! Your own safety and that of your environment is solely down to
you being responsible when dealing with the model.
• Improper operation can cause serious damage to people and property! Therefore, during operation, ensure a sufficient
safety distance to persons, animals and objects.
• Fly your model only if your ability to respond is unrestricted. The influence of tiredness, alcohol or medicine can
cause incorrect responses.
• The motor, the receiver/regulator unit and the flight battery can heat during operation. Therefore, take a break of 5
to 10 minutes before re-charging the flight battery or before flying with a possibly available spare flight battery.
• Always leave the remote control (transmitter) turned on, as long as the model is in operation. After landing, always
disconnect the flight battery for the receiver/regulator unit first. It is only afterwards that the remote control may be
turned off.
• Never switch the transmitter off during operation without disconnecting the flight battery from the receiver/control
unit.
• Don't expose your model and the remote control for a longer period of time to direct sunlight or excessive heat.
