PRECAUTIONS PLEASE READ CAREFULLY BEFORE PROCEEDING * Please keep this manual in a safe place for future reference. WARNING Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following: Do not open • Do not open the device or attempt to disassemble the internal parts or modify them in any way. The device contains no user-serviceable parts. If it should appear to be malfunctioning, discontinue use immediately and have it inspected by qualified Yamaha service personnel. Water warning • Do not expose the device to rain, use it near water or in damp or wet conditions, or place containers on it containing liquids which might spill into any openings. CAUTION Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the device or other property. These precautions include, but are not limited to, the following: Location • If you use a stand, check the stand's specifications and make sure that it is sturdy enough to support the weight of the speaker. You may need to limit the number of people around the placed stand, in order to avoid toppling the device or causing damage to the internal components. • If you use the TS-80 and TS-90 speaker stands manufactured by Ultimate Systems (sold separately) to support the S112V/S115V/SM10V/SM12V/SM15V speaker models, be sure to keep the following cautions. - Use the speaker stands with their legs fully opened. - Place only one speaker on each speaker stand. - Tighten fastening screws securely. - Remove the speakers from the stands before moving the stands or adjusting their height. - Add weight such as sand bags around the stand legs to prevent them from falling over. - Use the stand at a maximum height of 140 cm. • If you use a metal socket of the SW115V/SW118V subwoofer to allow mounting of a satellite speaker, use a pole shorter than 90cm with an outer diameter of 35mm. • When transporting or moving the device, always use two or more people. • Before moving the device, remove all connected cables. • Do not expose the device to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight, near a heater) to prevent the possibility of panel disfiguration or damage to the internal components. • Do not place the device in an unstable position where it might accidentally fall over. Connections • Before connecting the device to other devices, turn off the power for all devices. Before turning the power on or off for all devices, set all volume levels to minimum. • Use only speaker cables for connecting speakers to the speaker jacks. Use of other types of cables may result in fire. • Be sure to observe the amplifier's rated load impedance (see page 4), particularly when connecting speakers in parallel. Connecting an impedance load outside the amplifier's rated range can damage the amplifier. Handling caution • Do not use the device for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician. • Do not operate the device if the sound is distorting. Prolonged use in this condition could cause overheating and result in fire. • Always turn AC power to the power amplifier on last in any audio system to avoid speaker damage. When turning power off, the power amplifier should be turned off first for the same reason. 2
