Using the Unit Safely

•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” (separate leaflet).

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

•Always turn the unit off and unplug the power cord

before attempting installation of the circuit board (ARX series; p. 14).

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

•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 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 (p. 14).

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

•Whenever you suspect the possibility of lightning in

your area, pull the plug on the power cord out of the outlet.

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

•Install only the specified circuit board (ARX series).

Remove only the specified screws (p. 21).

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

•Should you remove screws of the ARX expansion

board cover (p. 21) or the rackmount brackets (p. 29), keep them in a safe place out of children's reach, so there is no chance of them being swallowed accidentally.
