Precautions - Yamaha NS-P270 Bedienungsanleitung

Precautions

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 Secure placement or installation is the owner's responsibility.
YAMAHA is not liable for accidents caused by improper
placement or installation of speakers.
9 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.
10 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.
11 Do not attempt to clean the speakers with chemical solvents
as this might damage the finish. Use a clean, dry cloth.
12 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.
13 Be sure to read the "Troubleshooting" section regarding
common operating errors before concluding that the
speakers are faulty.
This unit features a magnetically shielded design, but there
is still a chance that placing it too close to a TV set might
impair picture color. Should this happen, move this unit
away from the TV set.
For SW-P270
1 Do not operate this unit upside down. It may overheat,
possibly causing damage.
2 Do not use excessive force on switches, controls or
connection wires. When moving this unit, first disconnect
the power plug and the wires connected to other equipment.
Never pull the wires themselves.
3 Since this unit has a built-in power amplifier, heat radiates
from the rear panel. Place the unit away from walls,
allowing at least 20 cm of space above, behind and on both
sides of the unit to prevent fire or damage. Furthermore, do
not position the unit with the rear panel facing down on the
floor or other surfaces.
i
4 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.
5 Do not cover the rear panel of this unit with a newspaper,
tablecloth, curtain, etc. to avoid obstructing heat radiation.
If the temperature inside the unit rises, it may cause fire,
damage to the unit, or personal injury.
6 Do not plug this unit into a wall outlet until all connections
are complete.
7 The voltage to be used must match that specified on the
rear panel. Using this unit with a voltage higher than
specified is dangerous and may cause fire, damage to the
unit, and/or personal injury. YAMAHA is not responsible
for damage resulting from use of this unit with a voltage
other than specified.
8 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.
9 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.
10 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.
11 Vibration generated by super-bass sound may distort
images on a TV. In this case, move the unit away from the
TV set.
12 When disconnecting the power cord from the wall outlet,
grasp the plug; do not pull the cord.
13 When you plan not to use this unit for a long period of time
(i.e. vacation, etc.), disconnect the AC power plug from the
wall outlet.
14 Install this unit near the wall outlet and where the AC
power plug can be reached easily.
As long as this unit is connected to the AC wall outlet, it is
not disconnected from the AC power source even if you turn
off this unit by POWER.
