Precautions
 
• Before connecting the power cord, connect all of your 
speakers and AV components.
• Turning on the SKW-518 (HTP-518)/SKW-501 
(SKS-HT518) may cause a momentary power surge 
that might interfere with other electrical equipment on 
the same circuit. If this is a problem, plug the SKW-
518 (HTP-518)/SKW-501 (SKS-HT518) into a differ-
ent branch circuit.
 
Adjustment
 
To set the level of the subwoofer, use the OUTPUT 
LEVEL control. Set it so that bass sounds are evenly bal-
anced with the treble sounds from the other speakers.
Because our ears are less sensitive to very low bass 
sounds, there’s a temptation to set the level of the sub-
woofer too high. As a rule of thumb, set the subwoofer 
level to what you think is the optimal level, and then back 
it off slightly.
 
Operating Precautions
 
• 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 condi-
tioner, 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 dam-
age, will affect the sound quality.
• Subwoofer is designed to be used in the upright verti-
cal position only. Do not use it in the horizontal or 
tilted position.
• If the unit is used near a turntable, CD player or DVD 
player, howling or slipping of sound may occur. To 
prevent this, move the unit away from the turntable, 
CD player or DVD player otherwise lower the unit’s 
output level.
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-518F and SKC-518C 
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. Note that discol-
oration can also be caused by a magnet or demagnetizing 
tool that’s too close to your TV or monitor.
The speakers can handle the specified input power when 
used for normal music reproduction. If any of the follow-
ing 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, elec-
tronic 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.
