Cautions

Please read the following operating precautions before use:

•When you disconnect the AC power cable from an AC outlet, hold the plug, not the cord.

•If the YST-MS50s are not going to be used for a while, disconnect the AC power cord from the AC receptacle.

•Always disconnect the AC power cord from the AC receptacle before making any connections.

•The YST-MS50s 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-MS50s. Otherwise, you may cause a fire.

•Do not expose the YST-MS50s to temperature extremes, direct sunlight, excessive dust, humidity, or vibration.

•Position the YST-MS50s on a level, stable surface. Do not drop the YST-MS50s, apply excessive force to their controls, or put heavy items on top of them.

•Since this unit has a built-in power amplifier, heat will radiate from the rear panel. Therefore, place the unit away from walls, allowing a space of at least 20 cm (7.9") above, and 10 cm (4") behind and at the sides. Also, do not position with the rear panel facing down on the floor or other surface. (Subwoofer only)

•Do not obstruct the port with your hand or a foreign object.

•To protect the YST-MS50 speakers, avoid micro- phone feedback, continuous and excessive output from electronic musical instruments, and excessive signal distortion.

•If the YST-MS50s are located close to fluorescent or neon lights, a slight hum may be heard. In this case, relocate the YST-MS50s away from the light.

•Although the YST-MS50 speakers are magnetically shielded, keep floppy disks and tapes away from them.

•The YST-MS50s 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-MS50, first turn off the power to the speakers, then disconnect the power cable from the AC outlet 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.

•Do not turn off the POWER switch on the sub-

woofer while the (standby/on) button on the front panel of the right satellite speaker is on (while

the standby/on indicator is lit). Otherwise, the speakers may be damaged.

Note for headphone:

When you use headphones, make sure that they have a cable of less than 3m. (UK and Europe models)
