Yamaha YST-M40 Owner's Manual - Page 4

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 foreign object. • To protect the YST-M40 speakers, avoid microphone 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 appropriate level after the playback has started.
