Precautions
Speaker Precautions
1. AC Fuse—The AC fuse inside the unit is not user-
serviceable. If you cannot turn on the unit, contact
your Onkyo dealer.
Placement
• The subwoofer cabinet is made out of wood and is
therefore sensitive to extreme temperatures and
humidity, do not put it 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.
2. Care—Occasionally you should dust the unit all
over with a soft cloth. For stubborn stains, use a soft
cloth dampened with a weak solution of mild deter-
gent and water. Dry the unit immediately afterwards
with a clean cloth. Don’t use abrasive cloths, thin-
ners, alcohol, or other chemical solvents, because
they may damage the finish or remove the panel let-
tering.
3. Power
WARNING
BEFORE PLUGGING IN THE UNIT FOR THE
FIRST TIME, READ THE FOLLOWING SEC-
TION CAREFULLY.
AC outlet voltages vary from country to country.
Make sure that the voltage in your area meets the
voltage requirements printed on the unit’s rear panel
(e.g., AC 230 V, 50 Hz or AC 120 V, 60 Hz).
• 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.
The power cord plug is used to disconnect this unit
from the AC power source. Make sure that the plug
is readily operable (easily accessible) at all times.
Auto standby function does not fully shutdown the
SKW-750X. If you do not intend to use the SKW-
750X, remove the power cord from the AC outlet.
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-750XF and
SKC-750XC 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 per-
sist, try moving the speakers away from your TV or
monitor. Note that discoloration can also be caused by a
magnet or demagnetizing tool that’s too close to your
TV or monitor.
For Canadian models
For models having a power cord with a polarized plug:
CAUTION: TO PREVENT ELECTRIC SHOCK,
MATCH WIDE BLADE OF PLUG TO WIDE SLOT,
FULLY INSERT.

Do not place SKM-750XS/SKB-750X close to TV or a
computer monitor because they have no magnetic shield.
Input Signal Warning
The speakers can handle the specified input power when
used for normal music reproduction. If any of the fol-
lowing 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.
