(Do not drop it!) • Do not force the unit's power-supply cord to share an outlet with an unreasonable number of other devices. Be especially careful when using extension cords—the total power used by all devices you have connected to the extension cord's outlet must never exceed the power rating (watts/amperes) for the extension cord. Excessive loads can cause the insulation on the cord to heat up and eventually melt through. • Before using the unit in a foreign country, consult with your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the "Information" Page- • Do not put anything that contains water (e.g., flower vases) on this unit. Also, avoid the use of insecticides, perfumes, alcohol, nail polish, spray cans, etc., near the unit. Swiftly wipe away any liquid that spills on the unit using a dry, soft cloth. • The sub-woofer, L-channel satellite speaker, and R-channel satellite speaker of the DM-2100 must be used together. Never attempt to use them in combination with other devices. Doing so will cause malfunctions. Roland Corporation will accept no responsibility for malfunctions or other adverse effects that result due to your failure to use these components as a set. A CAUTION • The unit should be located so that its location or position does not interfere with its proper ventilation. • Always grasp only the plug on the power-supply cord when plugging into, or unplugging from, an outlet or this unit. • At regular intervals, you should unplug the power plug and clean it by using a dry cloth to wipe all dust and other accumulations away from its prongs. Also, disconnect the power plug from the power outlet whenever the unit is to remain unused for an extended period of time. Any accumulation of dust between the power plug and the power outlet can result in poor insulation and lead to fire. • Try to prevent cords and cables from becoming entangled. Also, all cords and cables should be placed so they are out of the reach of children. • Never climb on top of, nor place heavy objects on the unit. • Never handle the power cord or its plugs with wet hands when plugging into, or unplugging from, an outlet or this unit. • Before moving the unit, disconnect the power plug from the outlet, and pull out all cords from external devices. • Before cleaning the unit, turn off the power and unplug the power cord from the outlet. • Whenever you suspect the possibility of lightning in your area, pull the plug on the power cord out of the outlet. • The rear panel may become hot, so take care to avoid bums. 4 A CAUTION • The sub-woofer of the DM-2100 is designed to be placed on the floor. When in use, it must be placed in a stable position on the floor. You may place the L-channel satellite speaker and R-channel satellite speaker in the desired locations. • The side of the DM-2100 with the port is the front side. The main power switch is located on the rear of the unit. • Place the sub-woofer of the DM-2100 at a sufficient distance from the wall or any obstructing object so that you can reach the main power switch whenever necessary. • The area in the vicinity of the ports must be kept free of all obstructions. I IMPORTANT NOTES In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY on pages p. 2 and p. 3, please read and observe the following: Power Supply • Do not connect this unit to same electrical outlet that is being used by an electrical appliance that is controlled by an inverter (such as a refrigerator, washing machine, microwave oven, or air conditioner), or that contains a motor. Depending on the way in which the electrical appliance is used, power supply noise may cause this unit to malfunction or may produce audible noise. If it is not practical to use a separate electrical outlet, connect a power supply noise filter between this unit and the electrical outlet. • Before connecting this unit to other devices, turn off the power to all units. This will help prevent malfunctions and/or damage to speakers or other devices. • Although the LCD and LEDs are switched off when the POWER switch is switched off, this does not mean that the unit has been completely disconnected from the source of power. If you need to turn off the power completely, first turn off the POWER switch, then unplug the pow'er cord from the power outlet. For this reason, the outlet into which you choose to connect the power cord's plug should be one that is within easy reach. Placement • Using the unit near power amplifiers (or other equipment containing large power transformers) may induce hum. To alleviate the problem, change the orientation of this unit; or move it farther away from the source of interference. • This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers. • Noise may be produced if wireless communications devices, such as cell phones, are operate...
