• Utilize power outlets that are on different branch
circuits (circuit breaker or fuse) or install AC line
filter(s).
• In the case of radio or TV interference, relocate or
reorient the antenna. If the antenna lead-in is 300 ohm
ribbon lead, change the lead-in to a coaxial type cable.
If these corrective measures do not produce satisfactory
results, please contact the local retailer authorized to

For U.K. customers
If the socket outlets in the home are not suitable for the plug
supplied with this appliance, the plug should be cut off and
an appropriate 3 pin plug fitted. For details, refer to the
instructions described below.
Note:
The plug severed from the mains lead must be
destroyed, as a plug with bared flexible cord is hazardous if
engaged in a live socket outlet.
We Want You Listening for a Lifetime
YAMAHA and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most
enjoyment out of your equipment by playing it at a safe
level — a level that lets the sound come through loud and
clear without annoying blaring or distortion — and, most
importantly, without damaging your sensitive hearing.
Special Instructions for U.K. Model
IMPORTANT:
THE WIRES IN MAINS LEAD ARE COLOURED IN
ACCORDANCE WITH THE FOLLOWING CODE:
Blue: NEUTRAL
Brown: LIVE
As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured
markings identifying the terminals in your plug,
proceed as follows:
The wire which is coloured BLUE must be connected
to the terminal which is marked with the letter N or
coloured BLACK. The wire which is coloured BROWN
must be connected to the terminal which is marked
with the letter L or coloured RED.
Making sure that neither core is connected to the earth
terminal of the three pin plug.
Since hearing damage from loud sounds
is often undetectable until it is too late,
YAMAHA and the Electronic Industries
Association’s Consumer Electronics
Group recommend that you avoid prolonged exposure to excessive volume
levels.

Precautions
1To 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.
3To prevent the enclosure from warping or discoloring, do not
expose the speakers to direct sunlight or excessive humidity.
4Avoid 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.
9Any 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 speakers’ maximum input.
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 ve 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 the 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.
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, 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, or personal
injury. YAMAHA is not responsible for damage resulting
from use of this unit with a voltage other than specified.
8 Super-bass frequencies 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 the speaker system.
11 Vibration generated by super-bass frequencies 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.
WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR
MOISTURE.
For Canadian Customers
To prevent electric shock, match wide blade of plug to wide
slot and fully insert.
This Class B digital apparatus complies with Canadian
ICES-003.
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.
iii
•VOLTAGE SELECTOR
(For China, Korea, Asia and General models)
The voltage selector switch on the rear panel of this unit must be set for your local main voltage BEFORE
plugging this unit into the AC main supply. Voltages are 110-120/220-240 V AC, 50/60 Hz.
