Precautions

On safety

• Should any solid object or liquid fall into the subwoofer, unplug the system and have it checked by qualified personnel before operating it any further.
• Do not climb on the subwoofer, as you may fall down and injure yourself, or the subwoofer damage may result.

On power sources

• Before operating the subwoofer, check that the operating voltage is identical to your local power supply. The operating voltage is indicated on the nameplate at the rear of the subwoofer.
• If you are not going to use the subwoofer for a long time, be sure to disconnect the subwoofer from the wall outlet (mains). To disconnect the AC power cord (mains lead), grasp the plug itself; never pull the cord.
• One blade of the plug is wider than the other for the purpose of safety and will fit into the wall outlet (mains) only one way. If you are unable to insert the plug fully into the outlet, contact your dealer.
• AC power cord (mains lead) must be changed only at a qualified service shop.

On heat buildup

• Although the subwoofer heats up during operation, this is not a malfunction. If you continuously use this subwoofer at high volume, the subwoofer temperature at the rear and bottom rises considerably. To avoid burning yourself, do not touch the subwoofer.

On placement

• Do not place the subwoofer near heat sources or in a place subject to direct sunlight, excessive dust, or mechanical shock.
• Do not place metal objects other than a TV around the subwoofer. Wireless functions may be unstable.
• If the subwoofer is being used in combination with a TV, VCR, or tape deck, noise may result and picture quality may suffer. In such a case, place the subwoofer away from the TV, VCR, or tape deck.
• Use caution when placing the subwoofer on a surface that has been specially treated (with wax, oil, polish, etc.), as staining or discoloration of the surface may result.
• The speakers of this subwoofer are not of magnetically shielded type. Do not place magnetic cards on the subwoofer or near it.
