Precautions
—Continued
Before Using Your New Speakers
• Place the speakers on sturdy, flat surfaces. Putting
them on uneven or unstable surfaces where they may
fall and cause damage will affect the sound quality.
• Do not keep water or other liquids close to the
speakers. If a liquid is spilled over them, the woofer
and tweeter inside may be damaged.
• Do not handle the speakers with wet or damp hands.
Speaker Precautions
The speakers can handle the specified input power when
used for normal music reproduction. If they're fed any
of the following signals, 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. Audio from a cassette that's being fast-forwarded.
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.
The speakers contain powerful magnets. Do not put
metal items, such as screwdrivers, close to the speakers,
as they may be attracted toward the magnet, causing
injury, or damage to the tweeter diaphragm.
Using Close to a TV or Computer
TVs and computer monitors are magnetically sensitive
devices and as such are likely to suffer from
discoloration or picture distortion when conventional
speakers are placed nearby. To prevent this, the speakers
feature internal magnetic shielding. In some situations,
however, discoloration may still be an issue. In this
case, 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
discoloration can also be caused by a magnet or
demagnetizing tool that's too close to your TV or
monitor.
Note:
• If the speakers are placed close to a TV or monitor,
due to the electromagnetic waves radiated by the TV
or monitor, you may hear noise from the speakers even
after your amplifier has been turned off. To prevent
this, position the speakers away from your TV or
monitor.
