Important Information
• Hold the power cord plug when disconnecting it from an AC outlet. Never pull the cord. A
damaged power cord is a potential fire and electrical shock hazard.
• Do not touch the power plug with wet hands. Doing so is a potential electrical shock hazard.
• This unit has ventilation holes along the front underside and at the rear to prevent the inter-
nal 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. Other-
wise, 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.
• When setting up the product, make sure that the AC outlet you are using is easily accessible.
If some trouble or malfunction occurs, immediately turn off the power switch and discon-
nect the plug from the outlet. Even when the power switch is turned off, electricity is still
flowing to the product at the minimum level. When you are not using the product for a long
time, make sure to unplug the power cord from the wall AC outlet.
• If you know you will not use this unit for a long period of time, such as when going on vaca-
tion, 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.
• Do not apply oil, grease, or contact cleaner to the faders. Doing so may cause problems with
electrical contact or fader motion.
• Do not use the headphones 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 ring-
ing in the ears, consult a physician.

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, faders,
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.
