IMPORTANT NOTES
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 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 power 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 and readily accessible.
Placement
???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 operated in the vicinity of this unit. Such noise could occur when receiving or initiating a call, or while conversing. Should you experience such problems, you should relocate such wireless devices so they are at a greater distance from this unit, or switch them off.
???Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehicle, or otherwise subject it to temperature extremes. 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 conden- sation has completely evaporated.
???Depending on the material and temperature of the surface on which you place the unit, its rubber feet may discolor or mar the surface. You can place a piece of felt or cloth under the rubber feet to prevent this from happening. If you do so, please make sure that the unit will not slip or move accidentally.
???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.
Maintenance
???For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a cloth impregnated with a mild,
???Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.

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 write down save the important data you have stored in the unit???s memory on paper.
???Use a reasonable amount of care when using the unit???s buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions.
???When connecting / disconnecting all cables, grasp the connector
???A small amount of heat will radiate from the unit during normal operation.
???When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will need to use equivalent packaging materials.

About Connection Cables
Observe the following points with respect to the cables used for connections.
???Never use cables with damaged or torn coverings.
???Never step on cables or subject them to undue stress.
???Never wind cables too tightly or bend them double.
Along with the points just described, also observe the following points for specific cable types.
Coaxial Cables (75 ohm, BNC connectors)

???No single cable should be longer than 2,000 meters.
???Use cables having connectors compliant with ISO/IEC
REAC Cables
???Ensure that the cables used for REAC connections conform to the Cat 5e (Enhanced Category 5) standard.
???No single cable should be longer than 100 meters.
???To maintain transmission quality, use of the following optional REAC cables is recommended.
*Compared to analog transmission, digital transmission of audio signals by means of REAC (Roland Ethernet Audio Communication) is extremely resistant to external noise, but depending on the usage environment, in very rare instances, noise can occur. Selection of the wrong cable and incorrect cable handling are especially likely to cause noise.
About REAC Connector Covers
When using a commercially available Ethernet cable to connect a REAC device, fit the included REAC connector covers onto the REAC ports. Electromagnetic noise may be a problem if these are left unattached.
Attaching a REAC connector cover is not necessary when you???re using an optional REAC cable (described above).
