PRECAUTIONS PLEASE READ CAREFULLY BEFORE PROCEEDING * Please keep these precautions in a safe place for future reference. WARNING Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, shortcircuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following: • Do not open the instrument or attempt to disassemble the internal parts or modify them in any way. The instrument contains no user-serviceable parts. If it should appear to be malfunctioning, discontinue use immediately and have it inspected by qualified Yamaha service personnel. • Do not expose the instrument to rain, use it near water or in damp or wet conditions, or place containers on it containing liquids which might spill into any openings. • If the power cord or plug becomes frayed or damaged, or if there is a sudden loss of sound during use of the instrument, or if any unusual smells or smoke should appear to be caused by it, immediately turn off the power switch, disconnect the electric plug from the outlet, and have the instrument inspected by qualified Yamaha service personnel. • Only use the voltage specified as correct for the instrument. The required voltage is printed on the name plate of the instrument. • Always connect the three-pin attachment plug to a property grounded power source. (For more information about the main power supply, see "Power Connection".) • 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. CAUTION Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the instrument or other property. These precautions include, but are not limited to, the following: • Do not place the power cord near heat sources such as heaters or radiators, and do not excessively bend or otherwise damage the cord, place heavy objects on it, or place it in a position where anyone could walk on, trip over, or roll anything over it. • When removing the electric plug from the instrument or an outlet, always hold the plug itself and not the cord. Pulling by the cord can damage it. • Do not connect the instrument to an electrical outlet using a multiple-connector. Doing so can result in lower sound quality, or possibly cause overheating in the outlet. • Remove the electric plug from the outlet when the instrument is not to be used for extended periods of time, or during electrical storms. • 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. Also, be sure to set the volumes of all components at their minimum levels and gradually raise the volume controls while playing the instrument to set the desired listening level. • 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. • Do not place the instrument in an unstable position where it might accidentally fall over. • Before moving the instrument, remove all connected 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, plastic or rubber objects on the instrument, since this might discolor the panel or keyboard. • 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 place objects in front of the instrument's air vent, since this may prevent adequate ventilation of the internal components, and possibly result in the instrument overheating. To ensure adequate ventilation and cooling, leave at least 10cm of open space behind the A5000/A4000 rear panel, and at least 4cm of open space above the top cover. • 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. If you experience any hearing loss or ringing in the ears, consult a physician. s SAVING USER DATA • To protect against data loss caused by malfunction or operating error, be sure to save your data regularly to floppy disk, hard disk or other strage medium. Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed. Always turn the power off when the instrument is not in use. s Handling and Installation of Options WARNING • Before beginning installation, switch off the power to the A5000/A4000 and connected peripherals, and unplug them from the power outlet. Then remove all cables connecting the A5000/A4000 to other devices. (Leaving the power cord connected while working can result in electric shock. Leaving other cables connected can interfere with work.) • Do not disassemble, modify, or apply excessive force to board areas and connectors on option boards, hard disk, ZIP drive, and SIMMs. Bending or tampering with boards and connectors may lead to electric shock, fire, or equipment failures. CAUTION • Before handling an option board, hard disk, ZIP drive, or SIMM, you should briefly touch the A5000/A4000 metal casing (or other such metallic area) with your bare hand so as to drain off any static charge from your body. Note that even a slight amount of electrostatic discharge may cause damage to these components. • It is recommended that you wear gloves to protect your hands from metallic projections on the A5000/A4000, hard disk, SIMMs, ZIP drive, option boards, and other components. Touching leads or connectors with bare hands may cause finger cuts, and may also result in poor electrical contact or electrostatic damage. • Take care to avoid dropping screws into the A5000/A4000 unit. If a screw does fall in, be sure to remove it before you reassemble and power up the unit. Starting the unit with a loose screw inside may lead to improper operation or equipment failure. (If you are unable to retrieve a dropped screw, consult your Yamaha dealer for advice.) * Consult your Yamaha dealer if you have any questions regarding installation procedures for options boards, hard disks, SIMMs, or other optional devices. * If SIMM memory, hard disk, ZIP drive, or other optional component fails to work properly, consult the item's dealer for advice.
