Thank you for selecting this YAMAHA subwoofer system.

CAUTION: Read this before operating your unit.

English

● To assure the finest performance, please read this manual
carefully. Keep it in a safe place for future reference.

● Install this unit 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 this unit to rain or
water.

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

● To reduce the risk or fire or electric shock, do not expose this unit
to rain or moisture.

● Do not use force on switches, controls or connection wires.
When moving the unit, first disconnect the power plug and the
wires connected to other equipments. Never pull the wires
themselves.

● When not planning to use this unit for a long period (ie., vacation,
etc.), disconnect the AC power plug from the wall outlet.

● To prevent lightning damage, disconnect the AC power plug
when there is an electrical storm.

● 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 both sides of the unit to
prevent fire or damage. Furthermore, do not position with the
rear panel facing down on the floor or other surfaces.

<For U.K., Europe and China models only>

Be sure to allow space of at least 20 cm above, behind and on
both sides of the unit.

● Do not cover the rear panel of this unit with a newspaper, a
tablecloth, a curtain, etc. in order not to obstruct heat radiation. If
the temperature inside the unit rises, it may cause fire, damage
to the unit and/or personal injury.

● Do not place small metallic objects on this unit. Otherwise, the
object may fall, possibly causing an injury.

● Do not place the following objects on this unit:
Glass, china, etc.

If glass etc. falls by vibrations and breaks, it may cause
personal injury.

A burning candle etc.

If the candle falls by vibrations, it may cause fire and personal
injury.

A vessel with water in it

If the vessel falls by vibrations and water spills, it may cause
damage to the unit, and/or you may get an electric shock.

● Do not place this unit where foreign objects such as water drips
might fall. It might cause a fire, damage to this unit, and/or
personal injury.

● Never put a hand or a foreign object into the YST por t. When
moving this unit, do not hold the port as it might cause personal
injury and/or damage to this unit.

● Never open the cabinet. It might cause an electric shock since
this unit uses a high voltage. It might also cause personal injury
and/or damage to this unit.

● When using a humidifier, be sure to avoid condensation inside
this unit by allowing enough spaces around this unit or avoiding
excess humidification. Condensation might cause a fire, damage
to this unit, and/or electric shock.

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

● This unit may be damaged by using at high volume level when
20 Hz–50 Hz sine waves from a test disc, bass sounds from
electronic instruments, etc. are continuously inputted to this unit,
or when the stylus of a turntable touches the surface of a disc.
Reduce the volume level to prevent this unit from being
damaged.

● 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.

Vibration generated by super-bass frequencies may distort images

●

on a TV. In such a case, move this unit away from the TV set

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

● Be sure to read the “TROUBLESHOOTING” section regarding

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 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.

Standby mode
If the POWER switch is set to the ON position and the AUTO
STANDBY switch is set to the HIGH or LOW position, this unit
turns into the standby mode when no signal is received by this
unit for 7 to 8 minutes.
In this state, this unit is designed to consume a very small
quantity of power.
