11. deviation from the instructions may have an adverse effect on the function and operational security of the receiver and must be avoided under all circumstances Caution The operator bears full responsibility for using the receiver The only way to guard against personal injury and property damage is to handle the equipment carefully and use it exactly as recommended Caution Not suitable for children under fourteen years Caution Protect the receiver from dust soiling damp and foreign bodies Never subject the receiver to excessive vibration heat or cold Caution During the programming process you must bear in mind that an internal combustion engine or electric motor could unexpectedly burst into life at any time Caution Avoid subjecting the receiver to shocks and pressure Check the receiver regularly for damage to the case and cables Do not re use a receiver which is damaged or has become wet even after it has dried out again Caution When deploying the cables ensure that they are not under tension not tightly bent kinked or fractured Avoid sharp edges which could damage cable insulation Caution Ensure that all plug in connections are firmly seated Do not pull on the wires when disconnecting plugs and sockets Caution The receiver must not make physical contact with the model s fuselage hull or chassis as this would allow motor vibration and landing shocks to be transferred directly to it Caution It
