Yamaha NS-B20 Manual De Instrucciones página 3

Please read the following operating precautions before use. Yamaha will not be held responsible for any damage and/or
injury caused by not following the cautions below.
1. To assure the finest performance, please read this
manual carefully. Keep it in a safe place for future
reference.
2. Install the speakers in a cool, dry, clean place – away
from windows, sources of heat, sources of excessive
vibration, dust, moisture or cold. Avoid sources of
electrical humming (e.g., transformers and motors). To
prevent fire or electric shock, do not expose the
speakers to rain or water.
3. To prevent the enclosure from warping or discoloring,
do not expose the speakers to direct sunlight or
excessive humidity.
4. Avoid installing the speakers where foreign objects may
fall onto them and/or where they may be exposed to
liquid dripping or splashing.
5. Do not place the following objects on top of the speakers:
– Other components, as they might damage or discolor
the surface of the speakers.
– Burning objects (e.g., candles), as they might cause
fire, damage to the speakers or personal injury.
– Containers of liquid, as they might spill and cause
electric shock to the user or damage to the speakers.
6. Do not place the speakers where they are liable to be
knocked over or struck by falling objects. Stable
placement will also ensure better sound performance.
7. Placing the speakers on the same shelf or rack as the
turntable can result in feedback.
8. Any time you note distortion, reduce the volume control
on your amplifier to lower setting. Never allow your
amplifier to be driven into "clipping". Otherwise, the
speakers may be damaged.
9. When using an amplifier with a rated output power
higher than the nominal input power of the speakers,
care should be taken not to exceed the maximum input
of the speakers.
10. Do not attempt to clean the speakers with chemical
solvents as this might damage the finish. Use a clean,
dry cloth.
11. Do not attempt to modify or fix the speakers. Contact
qualified Yamaha service personnel when service is
needed. The cabinet should never be opened for any
reason.
12. Be sure to read the "Troubleshooting" section regarding
common operating errors before concluding that the
speakers are faulty.
13. Secure placement or installation is the owner's
responsibility. Yamaha is not liable for accidents
caused by improper placement or installation of
speakers.
For NS-SWP20
1. Do not operate this unit upside down. It may overheat,
possibly causing damage.
2. Never put a hand or a foreign object into the port
located on the right side of this unit. When moving this
unit, do not hold the port, as it might cause personal
injury and/or damage to this unit.
3. When using a humidifier, be sure to avoid condensation
inside this unit by allowing enough space around the
unit and avoiding excess humidification. Condensation
might cause fire, damage to the unit, and/or electric
shock.
Precautions
4. Super-bass sound reproduced by this unit may cause a
turntable to generate audio feedback. In this case, move
the unit away from the turntable.
5. This unit may be damaged if certain sounds are
continuously output at high volume level. For example,
if 20 Hz–50 Hz sine waves from a test disc or bass
sounds from an electronic instrument, etc. are
continuously output, or if a turntable stylus touches the
surface of a disc, reduce the volume level to prevent the
unit from being damaged.
6. If you hear distorted noise (i.e., unnatural, intermittent
"rapping" or "hammering" sounds) from this unit,
reduce the volume level. Extremely loud movie
soundtrack low frequency, bass-heavy sounds, or
similarly loud popular music passages can damage this
unit.
7. Vibration generated by super-bass sound may distort
images on a TV. In this case, move the unit away from
the TV set.
