We Want You Listening For A Lifetime
YAMAHA and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most out
of your equipment by playing it at a safe level. One that lets
the sound come through loud and clear without annoying

affecting your sensitive hearing.
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 you
to avoid prolonged exposure from excessive
volume levels.
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.

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.
● When you disconnect the AC adaptor from the AC
receptacle, hold the plug itself and not the cord.
● If you plan not to use YST-MS201 for a while, disconnect
the AC adaptor from the AC receptacle.
● Always disconnect the AC adaptor from the AC
receptacle before making any connections.
● YST-MS201 does not contain any user serviceable parts.
Refer all servicing to your Yamaha dealer.
● Never open the cabinet. If a foreign object drops into
the set, contact your dealer and stop using YST-MS201.
Otherwise, you may cause a fire.
● Do not expose YST-MS201 to extreme temperatures,
direct sunlight, excessive dust, humidity, or vibration.
● Position YST-MS201 on a level, stable surface. Do not
drop, apply excessive force to their controls, or put heavy
items on top of them.
●
Do not place small metallic objects on YST-MS201.
Otherwise, the object may fall, possibly causing an injury.
● Since the subwoofer has a built-in power amplifier, heat
will radiate from the rear panel. Place the subwoofer
apart from the walls, allowing a space of at least 20 cm
(7-7/8”) above, behind and on both sides of the
subwoofer. Also, do not position with the rear panel
facing down on the floor or other surfaces.
● Do not cover the rear panel of the subwoofer with a
newspaper, a tablecloth, a curtain, etc. in order not to
obstruct heat radiation. If the temperature inside the
subwoofer rises, it may cause fire, damage to the
subwoofer and/or personal injury.
● Do not place the following objects on YST-MS201:
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 YST-MS201, and/or you may get an
electric shock.
● To protect YST-MS201, avoid microphone feedback,
continuous and excessive output from electronic musical
instruments, and excessive signal distortion.
● If YST-MS201 is located close to fluorescent or neon
lights, a slight hum may be heard. In this case, relocate
YST-MS201 away from the light.
● Although YST-MS201 is magnetically shielded, keep
floppy disks and tapes away from it.
● Avoid sources of hum (transformers, motors). To prevent
fire or electrical shock, do not expose to rain or water.
● Do not use force on switches, knobs, or cables. When
you move YST-MS201, first turn off the power, then
disconnect the AC adaptor from the AC receptacle and
the cables from the connected devices.
● Always set the POWER/VOLUME control fully to the left
(in the standby mode) before starting to play the audio
source: turn the control gradually after the play has
started.
● Be sure to use the AC adaptor (PA-M30) supplied
with YST-MS201. Otherwise, you might cause a fire
or damage to YST-MS201.
Standby mode
When YST-MS201 is turned off by rotating the POWER/
VOLUME control, YST-MS201 consumes a small amount
of power. This state is called the standby mode. The
power supply is completely cut off from the AC line only
when the AC adaptor is disconnected.
YST-MS201 features a magnetically shielded design, but
there is still a chance that placing it too close to a TV or
a computer monitor might impair picture color. Should
this happen, move YST-MS201 away from the TV or the
computer monitor.
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.
