PrecautionsOn safety
Should any solid object or liquid fall into the cabinet, unplug the control center and have it checked by qualified personnel before operating it any further.
On power sources
•Before operating the unit, check that the operating voltage is identical with your local power supply. The operating voltage is indicated on the nameplate at the rear of the subwoofer.
•The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the control center itself has been turned off.
•If you are not going to use the system for a long time, be sure to disconnect the subwoofer from the wall outlet. To disconnect the AC power cord, grasp the plug itself; never pull the cord.
•AC power cord must be changed only at the qualified service shop.
On heat buildup
Although the unit heats up during operation, this is not a malfunction. If you continuously use this unit at a large volume, the cabinet temperature of the top, side and bottom rises considerably. To avoid burning yourself, do not touch the cabinet.
On placement
•Place the subwoofer in a location with adequate ventilation to prevent heat buildup and prolong the life of the subwoofer.
•Do not place the control center and subwoofer near heat sources, or in a place subject to direct sunlight, excessive dust or mechanical shock.
•Do not place anything on top of the cabinet that might block the ventilation holes and cause malfunctions.
•Use caution when placing the subwoofer or a speaker stand (not supplied) that is attached with the front/rear speakers on a specially treated (waxed, oiled, polished, etc.) floor, as staining or discoloration may result.
On operation
Before connecting other components, be sure to turn off and unplug the AC power cord of the subwoofer.
On cleaning
Clean the cabinet, panel and controls with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine.
