Yamaha DM2000 Owner's Manual - Page 4

ii • This unit has ventilation holes along the front underside and at the rear to prevent the internal temperature from rising too high. Do not block them. Blocked ventilation holes are a fire hazard. In particular, do not operate the unit while it's on its side, is upside down, or while it's covered with a cloth or dust sheet. • If you are using the optional MB2000 Peak Meter Bridge, do not hold only the MB2000 when you move the entire unit. Otherwise, the meter angle may be deformed or damaged, the main unit may malfunction, or you may be injured if the unit falls. • This unit is heavy. Use two or more people to carry it. • When you transport or move the DM2000 with the MB2000 attached, do not permit impact or stress on the cable connector that connects the MB2000 to the DM2000. Otherwise, malfunction may occur. • To relocate the unit, turn the power switch off, remove the power plug from the AC outlet, and remove all connecting cables. Damaged cables may cause fire or electrical shock. • If you know you will not use this unit for a long period of time, such as when going on vacation, remove the power plug from the AC outlet. Leaving it connected is a potential fire hazard. • The inside of the unit should be cleaned periodically. Dust accumulation inside the unit may cause malfunction and is a potential fire hazard. Consult your dealer for information about cleaning. • To prevent electrical shock when cleaning the unit, remove the power plug from the AC outlet. Operating Notes • XLR-type connectors are wired as follows: pin 1-ground, pin 2-hot (+), and pin 3-cold (-). • Insert TRS phone jacks are wired as follows: sleeve-ground, tip-send, and ring-return. • The performance of components with moving contacts, such switches, rotary controls, fad- ers, and connectors, deteriorates over time. The rate of deterioration depends on the operating environment and is unavoidable. Consult your dealer about replacing defective components. • Using a mobile telephone near this unit may induce noise. If noise occurs, use the telephone away from the unit. • If the message "WARNING Low Battery!" appears when you turn on this unit, contact your dealer as soon as possible about replacing the internal data backup battery. The unit will still operate correctly, but data other than the presets will be lost. • Before replacing the batteries, back up your data to a memory card, or another unit by using MIDI Bulk Dump. • The digital circuits of this unit may induce a slight noise into nearby radios and TVs. If noise occurs, relocate the affected equipment. • When connecting D-sub cables, be sure to tighten the screws on both sides of the connector securely. To disconnect the cable, loosen the screws completely, then remove the cable by holding the connector part. Do not remove the plug by pulling the cable while the screws are still attached. Otherwise, the connector may be damaged, leading to malfunction. • When you change the wordclock settings on any device in your digital audio system, some devices may output noise, so turn down your power amps beforehand, otherwise your speakers may be damaged.
