Thank you for purchasing Yamaha’s YST-M15/M20DSP Powered Speakers. Yamaha’s Active Servo Technology offers exceptional high performance.

Cautions

Please read the following operating precautions before use:

•Use the AC adaptor designed specifically for the YST-M15/M20DSP only. Yamaha cannot be held responsible for damage caused by using other power supply adaptors.

•When disconnecting the AC adaptor from an AC receptacle, hold and pull the adaptor, not the power cord.

•If the YST-M15/M20DSPs are not going to be used 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-M15/M20DSPs do not contain any user serviceable parts. Refer all servicing to your Yamaha dealer.

•Do not expose the YST-M15/M20DSPs to temperature extremes, direct sunlight, excessive dust, humidity, or vibration.

•Place the YST-M15/M20DSPs on a level, stable surface. Do not drop the YST-M15/M20DSPs, apply excessive force to their controls, or put heavy items on top of them.

•If the YST-M15/M20DSPs should require cleaning, use a soft cloth. If necessary, use a damp cloth.

•To protect the YST-M15/M20DSP speakers, avoid microphone feedback, continuous and excessive output from electronic musical instruments amplifiers signal distortion.

•If the YST-M15/M20DSPs are located close to fluorescent or neon type lights, a slight hum may be heard. In this case, relocate the YST-M15/M20DSPs away from the light.

•Although the YST-M15/M20DSP speakers are magnetically shielded, keep floppy disks and tapes away from them.

•The YST-M15/M20DSPs may cause picture distortion when placed close to a television or computer monitor. In this case, move them away a little.

CAUTION

The apparatus is not disconnected from the AC power source as long as it is connected to the wall outlet, even if the apparatus itself is turned off.

CAUTION (FOR CANADA MODEL): TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT AND FULLY INSERT.

Connections

Refer to page 2 for system connections.

Rear Panel (right cabinet) (Refer to page 3)
