•In households with small children, an adult should provide supervision until the child is capable of following all the rules essential for the

safe operation of the unit.

..........................................................................................................

•Protect the unit from strong impact. (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” sheet.

..........................................................................................................

•Batteries must never be recharged, heated, taken apart, or thrown into fire or water.

..........................................................................................................

•The unit and the AC adaptor should be located so their location or position does not interfere with

their proper ventilation.

..........................................................................................................

•Always grasp only the output plug or the body of the AC adaptor when plugging into, or

unplugging from, this unit or an outlet.

..........................................................................................................

•At regular intervals, you should unplug the AC adaptor 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 AC adaptor body, or its output plugs, with wet hands when plugging into, or unplugging from, an outlet or this unit.

..........................................................................................................

• Before moving the unit, disconnect the AC adaptor and all cords coming from external devices.

..........................................................................................................

•Before cleaning the unit, turn off the power and unplug the AC adaptor from the outlet.

..........................................................................................................

• Whenever you suspect the possibility of lightning in your area, disconnect the AC adaptor from the outlet.

..........................................................................................................

•If used improperly, batteries may explode or leak and cause damage or injury. In the interest of safety, please read and observe the following

precautions (p. 6).

•Carefully follow the installation instructions for batteries, and make sure you observe the correct polarity.

•Avoid using new batteries together with used ones. In addition, avoid mixing different types of batteries.

•Remove the batteries whenever the unit is to remain unused for an extended period of time.

•If a battery has leaked, use a soft piece of cloth or paper towel to wipe all remnants of the discharge from the battery compartment. Then install new batteries. To avoid inflammation of the skin, make sure that none of the battery discharge gets onto your hands or skin. Exercise the utmost caution so that none of the discharge gets near your eyes. Immediately rinse the affected area with running water if any of the discharge has entered the eyes.

•Never keep batteries together with metallic objects such as ballpoint pens, necklaces,

hairpins, etc.

..........................................................................................................

•Used batteries must be disposed of in compliance with whatever regulations for their safe disposal

that may be observed in the region in which you live.
