CAUTION

CAUTION: READ THIS BEFORE OPERATING YOUR UNIT.

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, heat sources, sources of excessive
vibration, dust, moisture and cold. Avoid sources of
humming (transformers, motors). To prevent fire or
electrical shock, do not expose the speakers to rain or
water.

3. To prevent the enclosure from warping or discoloring,
do not place the speakers where they will be exposed
to direct sunlight or excessive humidity.

4. 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.

5. Placing the speakers on the same shelf or rack as the
turntable can result in feedback.

6. As these speakers contain strong magnets (though all
of them are magnetically shielded types), avoid placing
watches, magnetic tapes, etc. near them. Also, placing
the speakers near a TV set may impair picture color. If
this happens, move the speakers a way from the TV set.

7. Do not attempt to clean the speakers with chemical
solvents as this might damage the finish. Use a clean,
dry cloth.

8. Be sure to read the “TROUBLESHOOTING” section
regarding common operating errors before
concluding that the unit is faulty.

9. Secure placement or installation is the owner’s
responsibility. YAMAHA shall not be liable for any
accident caused by improper placement or
installation of speakers.

■ For U.K. customers

If the socket outlets in the home are not suitable for the plug
supplied with this appliance, it 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.

■ 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.

■ For SW-AVS70

1. Never open the cabinet. If something drops into the
set, contact your dealer.

2. Do not use force on switches, controls or connection
cables. When moving the unit, first disconnect the
power cord and the cables connected to other
components. Never pull the cables themselves.

3. When not planning to use this unit for a long period
of time (e.g., vacation), disconnect the AC power
cord from the wall outlet.

4. To prevent lightning damage, disconnect the AC
power cord when there is an electric storm.

5. Since this unit has a built-in power amplifier, heat
will radiate from the rear panel. Place the unit apart
from the walls, allowing enough space above, behind
and on the both sides of the unit to prevent fire or
damage. Furthermore, do not position with the rear
panel facing down the floor or other surfaces.

6. Super-bass frequencies reproduced by this unit may
cause a turntable to generate a howling sound. In
such a case, move this unit a way from the turntable.

7. If you hear distorted noise (i.e., unnatural,
intermittent “rapping” or “hammering” sounds)
coming from this unit, reduce the volume level.
Extremely loud playing of a movie soundtrack’s low
frequency, bass-heavy sounds or similarly loud
popular music passages can damage this speaker
system.

WARNING

TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR
MOISTURE.
