These precautions include, but are not limited to, the following: • Do not expose the instrument to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent the possibility of panel disfiguration or damage to the internal components. • Do not use the instrument"near other electrical products such as televisions, radios, or speakers, since this might cause interference which can affect proper operation of the other products. • Before moving the instrument, remove all connected adaptor and other cables. • When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths. Also, do not place vinyl or plastic objects on the instrument, since this might discolor the panel. • Do not rest your weight on, or place heavy objects on the instrument, and do not use excessive force on the buttons, switches or connectors. • Do not operate the instrument for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss.

Doing so can result in lower sound quality, or possibly cause overheating in the outlet. • Unplug the AC power adaptor when not using the instrument, or during electrical storms. • Always make sure all batteries are inserted in conformity with the +/- polarity markings. Failure to do so might result in overheating, fire, or battery fluid leakage. • Do not dispose of batteries in fire. • Do not attempt to recharge batteries that are not intended to be charged. • If the instrument is not to be in use for a long time, remove the batteries from it, in order to prevent possible fluid leakage from the battery. • Keep batteries away from children. • Before connecting the instrument to other electronic components, turn off the power for all components. Before turning the power on or off for all components, set all volume levels to minimum. • Use the specified adaptor (PA-1 /1B, PA-3B, or an equivalent recommended by Yamaha) only. Using the wrong adaptor can result in damage to the instrument or overheating. • Before cleaning the instrument, always remove the electric plug from the outlet. Never insert or remove an electric plug with wet hands. • Check the electric plug periodically and remove any dirt or dust which may have accumulated on it. • INTRODUCTION Thank you for purchasing the Yamaha FC9 foot controller.
