Important Precautions Read the following before operating the Disklavier control unit. ■ Warnings • Do not locate the Disklavier control unit in a place subject to excessive heat, low temperatures, or direct sunlight. This could be a fire hazard and may damage the finish and internal parts. • Excessive humidity or dust can lead to fire or electric shock. • Connect the plug of the AC adaptor to a compatible AC outlet. Failure to do so will present a fire and electric shock hazard. If the AC adaptor is not compatible with your AC outlet, consult your dealer. • Do not plug several devices into the same AC outlet. This can overload the AC outlet, and lead to fire and electric shock hazard. It may also affect the performance of some devices. • Do not place heavy objects on the AC adaptor cable. A damaged cable is a potential fire and electric shock hazard. If the cable runs under a carpet, make sure heavy objects are not placed on top of the cable. • If the AC adaptor cable is damaged (i.e. cut or a bare wire is exposed), ask your dealer for a replacement. Using the Disklavier control unit in this condition is a fire and shock hazard. • When disconnecting the AC adaptor cable from an AC outlet, always pull from the plug. Never pull the cable. Damaging the cable in this way is a potential fire and electric shock hazard. • The cover of the unit should be removed only by qualified service technicians. • Do not place liquid containers such as vases, potted plants, glasses, cosmetic bottles, medicines, etc., on the Disklavier control unit. • Do not try to modify the Disklavier control unit, as this could lead to fire or electric shock hazard. • When moving the Disklavier control unit to another location, turn off the power, remove the AC adaptor from the AC outlet, and remove all cables connected to external devices. • Use only the specified AC adaptor. Use of other AC adaptors may result in damage, overheating, or fire. ■ Cautions • Turn off all audio devices when connecting to the Disklavier control unit. Refer to the user's guide for each device. Use the correct cables and connect as specified. • Set the volume level on all the devices to minimum before applying power. • Do not play the Disklavier control unit at a high volume for extended periods; you may damage your hearing. This is especially important when using headphones. If you think your hearing ability is impaired, consult your doctor. • If the Disklavier control unit is worked extremely hard - that is, prolonged playback of very "busy" songs - the thermal relay of the Disklavier control unit may trip. The thermal relay will automatically reset when the Disklavier control unit has cooled down. • If you notice any abnormality - such as smoke, odor, or noise - turn off the Disklavier control unit immediately, and remove the AC adaptor from the AC outlet. Consult your dealer for repair. • If a foreign object or water gets inside the Disklavier control unit turn it off immediately, and remove the power plug from the AC outlet. Consult your dealer. • If you plan not to use the Disklavier control unit for a long period of time (such as when you are on vacation), disconnect the AC adaptor from the AC outlet. • Always remove the AC adaptor from the AC outlet before cleaning the Disklavier control unit. Leaving the AC adaptor connected presents a risk of electric shock. • Do not use benzene, thinner, cleaning detergent, or a chemical cloth to clean the Disklavier control unit. • Do not place metal objects with rubber feet on the Disklavier control unit. The color and finish of the Disklavier control unit can be damaged. • Do not place heavy objects on the Disklavier control unit. Doing so can damage the Disklavier control unit. • Use a soft, dry cloth to clean the Disklavier control unit. However, if you discover a stain, carefully use a soft damp cloth to remove it. ii
