Cautions
Please read the following operating precautions before use:
• When disconnecting the power cord from an AC receptacle, hold
and pull the plug, not the cord.
• If the YST-SW20 is not going to be used for a while, disconnect it
from the AC receptacle.
• Since this unit has a built-in power amplifier, heat will radiate from
the rear panel. Therefore, place the unit at least 10 cm (4 inches)
away from the wall. Also, do not position with the rear panel
facing down on the floor or other surface.
• Always disconnect from the AC receptacle before making any
connections.

servicing to your Yamaha dealer.

sunlight, excessive dust, humidity, or vibration.
• Site the YST-SW20 on a level, stable surface. Do not drop the
YST-SW20, apply excessive force to its controls, or put heavy
items on top of it.
• If the YST-SW20 should require cleaning, use a soft cloth. If
necessary, a damp cloth.
• Do not to put some objects into it. If doing so, the sound will be
unnatural or it may cause damage to the speaker and/or amplifier.
• To protect the YST-SW20 speaker, avoid microphone feedback,
continuous and excessive output from electronic musical instru-
ments, excessive signal distortion,
• Although the YST-SW20 is magnetically shielded, keep floppy
disks and tapes away from it.

television or computer monitor. In this case, move it away a little.
