Operating Precautions; Troubleshooting - Onkyo SKS-HT530 Instruction Manual

Operating Precautions

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 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 or CD player, howl-
ing 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.

Troubleshooting

Symptom
There's no sound coming
from certain speakers?
The subwoofer does not
turn on?
The subwoofer produces
no sound?
The subwoofer produces
hardly any sound?
A humming sound can be
heard from the sub-
woofer?
Possible cause
The speaker cables are not connected properly.
The speaker configuration is not set correctly.
The power plug is not fully inserted into the wall
outlet.
The OUTPUT LEVEL control is set to minimum.
The RCA cable is not properly connected to the
subwoofer's LINE INPUT.
The level of the input signal was too low and the
subwoofer entered Standby mode.
The Subwoofer configuration is not set correctly.
The source material contain little or no bass con-
tent.
The RCA cable is not properly connected to the
subwoofer's LINE INPUT.
External interference from a TV or other elec-
tronic device is being picked up.
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-530F and SKC-530C
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.
Input Signal Warning
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.
Remedy
Check the speaker cables and correct as necessary.
Check the speaker configuration.
Insert the power plug fully into the wall outlet.
Turn up the OUTPUT LEVEL control.
Make sure that the RCA cable is properly connected to
the subwoofer's LINE INPUT.
Slightly increase the subwoofer pre out output level on
your AV receiver.
Check the subwoofer setting in the speaker configura-
tion on your AV receiver.
Choose source material with more bass content.
Make sure that the RCA cable is properly connected to
the subwoofer's LINE INPUT.
Move the subwoofer and RCA cable away from the
interference source. Make sure your audio system is
grounded properly.
