Facilità d'uso
Also, do not allow lighting devices that normally are used while their light source is very close to the unit (such as a piano light), or powerful spotlights to shine upon the same area of the unit for extended periods of time. Excessive heat can deform or discolor the unit. • When moved from one location to another where the temperature and/or humidity is very different, water droplets (condensation) may form inside the unit. Damage or malfunction may result if you attempt to use the unit in this condition. Therefore, before using the unit, you must allow it to stand for several hours, until the condensation has completely evaporated. • Do not allow rubber, vinyl, or similar materials to remain on the unit for long periods of time. Such objects can discolor or otherwise harmfully affect the finish. • Do not allow objects to remain on top of the keyboard. This can be the cause of malfunction, such as keys ceasing to produce sound. • Do not paste stickers, decals, or the like to this instrument. Peeling such matter off the instrument may damage the exterior finish. Maintenance • (RG-1F) To clean the unit, use a dry, soft cloth; or one that is slightly dampened. Try to wipe the entire surface using an equal amount of strength, moving the cloth along with the grain of the wood. Rubbing too hard in the same area can damage the finish. • (RG-3F) Since your piano has a polished finish that is as delicate as that found on finely crafted wooden furniture, it needs careful, periodic care. A few important suggestions concerning the proper care of the unit follow. • For dusting, using a soft, clean cloth and/or piano-use feather duster. Be sure to wipe gently. Even the tiniest grains of sand or grit can leave scratches on the surface if too much force is applied while wiping. Do not use any cleaners or detergents, since they might deteriorate the surface of the cabinet, and produce cracks. • If the cabinet’s surface loses its luster, wipe it thoroughly with a soft cloth dampened with a little of the polishing liquid. Do not use any cleaners or detergents, since they might deteriorate the surface of the cabinet, and produce cracks. Do not use dusting cloths that contain chemicals. • Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation. • The pedals of this unit are made of brass. Brass eventually darkens as the result of the natural oxidization process. If the brass becomes tarnished, polish it using commercially available metal polisher. Repairs and Data • Please be aware that all data contained in the unit’s memory may be lost when the unit is sent for repairs. Important data should always be backed up on a USB memory, or written down on paper (when possible). During repairs, due care is taken to avoid the loss of data. However, in certain cases (such as when circuitry related to memory itself is out of order), we regret that it may not be possible to restore the data, and Roland assumes no liability concerning such loss of data. Using USB Memory (Using Optional USB memory) • Do not connect or disconnect USB memory while it is being read from, or written to (i.e., while the USB memory access indicator will blink). • Carefully insert the USB memory all the way in—until it is firmly in place. • Never touch the terminals of the USB memory. Also, avoid getting the terminals dirty. • USB memories are constructed using precision components; handle the USB memories carefully, paying particular note to the following. • To prevent damage to the USB memories from static electricity, be sure to discharge any static electricity from your own body before handling the USB memories. • Do not touch or allow metal to come into contact with the contact portion of the USB memories. • Do not bend, drop, or subject USB memories to strong shock or vibration. • Do not keep USB memories in direct sunlight, in closed vehicles, or other such locations. • Do not allow USB memories to become wet. • Do not disassemble or modify the USB memories. IMPORTANT NOTES Handling CD-ROMs (Using Optional CD-ROMs) • Avoid touching or scratching the shiny underside (encoded surface) of the disc. Damaged or dirty CD-ROM discs may not be read properly. Keep your discs clean using a commercially available CD cleaner. Additional Precautions • Please be aware that the contents of memory can be irretrievably lost as a result of a malfunction, or the improper operation of the unit. To protect yourself against the risk of loosing important data, we recommend that you periodically save a backup copy of important data you have stored in the unit’s memory on a USB memory. • Unfortunately, it may be impossible to restore the contents of data that was stored in the unit’s memory or on a USB memory once it has been lost. Roland Corporation assumes no liability concerning such loss of data. • Use a reasonable amount of care when using the unit’s buttons, sliders, or other controls; and when using its jac...
