1. Place the supplied template on the panel and then mark the hole positions. 2. Cut open a large hole and make screw holes. 3. Peel off the covering sheet from the spacer, and attach the spacer on the back of the speaker flange so that the flange is completely covered.
First, check the power of the amplifier. If the power of the amplifier is higher than the subwoofers rated input power, increase the number of subwoofers so that the power fed to each subwoofer is lower than its rated input power, or lower the sensitivity of the amplifier. Supplying power greater than its rated input power of the subwoofer will cause noise and/or breakage. Also, if using multiple subwoofers, be careful about the total impedance. Change the connecting pattern of the speakers according to the capable impedance of the amplifier.
The sensitivity of the power amplifier should be set to the same value as the preoutput volume of the CD player or Tuner.

IMPORTANT SAFEGUARDS

Caution : Read this page carefully to keep your safety.
1. Suffocation After taking the unit out of the polyethylene bag, be sure to dispose of the polyethylene bag out of the reach of children. Otherwise, they may play with the bag, which could cause hazard of suffocation.
2. Power supply voltage Connect the illumination lampe q u i p p e d s p e a k e r s t o D C V, negative ground. SUBWOOFER
3. Water and moisture Do not install the speakers in locations which may be subject to water or moisture.

INSTRUCTION MANUAL

4. Dust and unstable locations Do not install the speakers in unstable locations or locations subject to dust.
5. Modification Do not attempt to open or modify the unit, for this could cause fire hazard or malfunction.

B61-1309-00 (MND)

6. Cleaning Do not use gasoline, naphtha, or any type of solvent to clean the speakers. Clean by wiping with a soft, dry cloth.
7. Malfunction In the event the unit generates smoke or abnormal smell or no sound comes out from the speaker, immediately switch the power OFF. After this, please contact your dealer or nearest service station as soon as possible.

POWER OFF!

, , , ,
Observe the following cautions to prevent damage to the speakers. You cannot input the same power as peak power continually. When the volume is set too high, the sound may be distorted or abnormal. Reduce the volume promptly in case of such phenomena. While the listening volume is set to a high level, do not load or eject a disc or cassette tape or operate the selector and power switches of the amplifier.
