Cautions
Please read the following operating precautions before use:
• When you disconnect the AC adaptor from the AC
receptacle, hold the plug, not the cord.
• If you plan not to use the YST-M40s for a while,
disconnect the AC adaptor from the AC receptacle.
• Always disconnect the AC adaptor from the AC
receptacle before making any connections.
• The YST-M40s do 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 do not use the
YST-M40s. Otherwise, you may cause a fire.
• Do not expose the YST-M40s to temperature
extremes, direct sunlight, excessive dust, humidity,
or vibration.
• Position the YST-M40s on a level, stable surface.
Do not drop the YST-M40s, apply excessive force
to their controls, or put heavy items on top of them.
• Do not place small metal objects on the speakers.
Otherwise, the object may fall, possibly causing an
injury.
• Do not obstruct the port with your hand or a for-
eign object.
• To protect the YST-M40 speakers, avoid micro-
phone feedback, continuous and excessive output
from electronic musical instruments, and excessive
signal distortion.
• If the YST-M40s are located close to fluorescent or
neon lights, a slight hum may be heard. In this
case, relocate the YST-M40s away from the light.
• Although the YST-M40 speakers are magnetically
shielded, keep floppy disks and tapes away from
them.
• The YST-M40s may cause picture distortion when
located close to a television or computer monitor.
In this case, move them away a short distance.
• Avoid sources of hum (transformers, motors). To
prevent fire or electrical shock, do not expose to
rain and water.
• Do not use force on switches, knobs, or cables.
When you move the YST-M40, first turn off the
power to the speakers, then disconnect the AC
adaptor from the AC receptacle and the cables
from the connected devices.
• Always turn the volume control counterclockwise
to the minimum before starting to play the audio
source: increase the volume gradually to an appro-
priate level after the playback has started.

About YMERSION (3D Enhancement)
YMERSION is Yamaha’s proprietary technology that enhances the spread of a normal stereo source play-
back sound, creating three-dimensional acoustics using only two speakers.
The 3D SURROUND switch on the right speaker enables you to turn the YMERSION effect on and off.
Troubleshooting
If the speakers fail to operate normally, check the following table. It lists common operation errors and simple mea-
sures that you can take to correct problems. If a problem cannot be corrected, or the symptom is not listed, discon-
nect the AC adaptor and contact your authorized YAMAHA dealer or service center for help.
Even if the (standby/on) button is turned off, a small amount of sound may be heard from the headphones if the
VOLUME control is set to max. This is normal.
