Caring for Your Speakers Placement • The speaker cabinets are made out of wood and are therefore sensitive to extreme temperatures and humidity, do not put them in locations subject to direct sunlight or in humid places, such as near an air conditioner, humidifier, bathroom, or kitchen. • Do not put water or other liquids close to the speakers. If liquid is spilled over the speakers, the drive units may be damaged. • Speakers should only be placed on sturdy, flat surfaces that are free from vibration. Putting them on uneven or unstable surfaces, where they may fall and cause damage, will affect the sound quality. • Subwoofer is designed to be used in the upright vertical position only. Do not use it in the horizontal or tilted position. • If the unit is used near a turntable or CD player, howling or slipping of sound may occur. To prevent this, move the unit away from the turntable or CD player otherwise lower the unit's output level. Using Close to a TV or Computer TVs and computer monitors are magnetically sensitive devices and as such are likely to suffer discoloration or picture distortion when conventional speakers are placed nearby. To prevent this, the SKF-320F and SKC-320C speakers feature internal magnetic shielding. In some situations, however, discoloration may still be an issue, in which case you should turn off your TV or monitor, wait 15 to 30 minutes, and then turn it back on again. This normally activates the degaussing function, which neutralizes the magnetic field, thereby removing any discoloration effects. If discoloration problems persist, try moving the speakers away from your TV or monitor. Troubleshooting Note that discoloration can also be caused by a magnet or demagnetizing tool that's too close to your TV or monitor. Do not place SKM-320S close to TV or a computer monitor because it has no magnetic shield. Operating Precautions The HTP-320 speakers can handle the specified input power when used for normal music reproduction. If any of the following signals are fed to them, even if the input power is within the specified rating, excessive current may flow in the speaker coils, causing burning or wire breakage: 1. Interstation noise from an untuned FM radio. 2. Sound from fast-forwarding a cassette tape. 3. High-pitched sounds generated by an oscillator, electronic musical instrument, and so on. 4. Amplifier oscillation. 5. Special test tones from audio test CDs and so on. 6. Thumps and clicks caused by connecting or discon- necting audio cables (Always turn off your amplifier before connecting or disconnecting cables.) 7. Microphone feedback. Speaker Care Wipe the cabinet occasionally with a dry silica or soft cloth. For heavier dirt, after dampening a soft cloth in a weak solution of mild detergent and water and wringing it out dry, wipe off the dirt. Then, dry immediately with a clean cloth. Do not use rough material, thinners, alcohol or other chemical solvents or cloths since these could damage the finish, remove the panel lettering, or cause discoloration. If you are using a chemical cloth, always follow the instructions that come with the cloth. For dust accumulated on grilles, use a vacuum cleaner or brush it off.
