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-MS55Ds are not going to be used for a while, disconnect the AC power cord from the AC outlet.

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

•The YST-MS55Ds do not contain any user service- able 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-MS55Ds. Otherwise, you may cause a fire.

•Do not expose the YST-MS55Ds to temperature extremes, direct sunlight, excessive dust, humidity, or vibration.

•Position the YST-MS55Ds on a level, stable sur- face. Do not drop the YST-MS55Ds, apply exces- sive 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 apart from the walls, allowing a space of at least 20 cm (7-7/8") above, behind and on the both sides of the unit. 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 for- eign object.

•To protect the YST-MS55D speakers, avoid micro- phone feedback, continuous and excessive output from electronic musical instruments, and excessive signal distortion.

•If the YST-MS55Ds are located close to fluores- cent or neon lights, a slight hum may be heard. In this case, relocate the YST-MS55Ds away from the light.

•Although the YST-MS55D speakers are magneti- cally shielded, keep floppy disks and tapes away from them.

•The YST-MS55Ds may cause picture distortion when located close to a television or computer monitor. In this case, move them away a short dis- tance.

•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-MS55D, 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.

•Voltage Selector (General Model only)

The voltage selector on the rear panel of this unit must be set for your local main voltage before plugging into the AC main supply.

•Though this speaker is a magnetically shielded type, there may be some influence on the monitor picture depending on the type of monitor or the placement of the speaker. In such a case, place the speaker further apart from the monitor until there is no influence on the monitor picture.
