CONSUMER PRECAUTIONS
Read these precautions carefully before installing your NS-IW660 speaker.
z
  Before you begin installation, read this owner’s manual completely and consult your local building codes. If you 
have any doubts or reservations, contact your dealer or a qualified audio/video installer. 
z
  YAMAHA recommends installing the speaker only in two-by-four wood frame or similar construction. The 
instructions provided in this owner’s manual are intended specifically for this type of wall construction. 
z
  When installing your NS-IW660 in-wall speaker, be aware of the product weight (See specification page) and 
the sturdiness of the material into which you are installing the speaker. 
z
  Be aware of any concealed studs, electrical wiring or plumbing in the wall or ceiling into which you are 
installing the speakers. If you are not sure of a safe way to install these speakers, consult a professional 
installer or a building contractor.
z
  Never touch the speaker units with your hands or expose them to excessive physical shock. If they are dented 
or bent, the sound will be distorted.
z
  Lower the power amplifier/receiver volume control before changing input sources. Never change input sources 
(for example, FM to CD) at high listening levels. Always turn the receiver/amplifier unit off when installing or 
removing any cables.
z
  Anytime you note distortion, reduce the volume control on your power amplifier/receiver to a lower setting. 
Never allow your power amplifier to be driven into  “clipping”.
z
  Secure placement or installation is the owner’s responsibility. YAMAHA shall not be liable for any accident 
caused by improper placement or installation of speakers.
WARNING:
Installation shall be in accordance with the applicable section of the National Electrical Code, ANSI/NFPA 70, 
and/or the National Fire Alarm Code, ANSI/NFPA 72, as applicable. The wiring method and compartment shall 
be such as not to interfere with the operation of the speaker.
