While the following statements are provided to comply with FCC Regulations in the United States,
the corrective measures listed below are applicable worldwide.
This series of Yamaha professional music equipment uses frequencies that appear in the radio fre-
quency range and if installed in the immediate proximity of some types of audio or video devices
(within three meters), interference may occur. This series of Yamaha combo equipment have been
type tested and found to comply with the specifications set for a class B computing device in ac-
cordance with those specifications listed in subpart J of part 15 of the FCC rules. These rules are
designed to provide a reasonable measure of protection against such interference. However, this
does not guarantee that interference will not occur. If your professional music equipment should
be suspected of causing interference with other electronic devices, verification can be made by turning
your combo equipment off and on. If the interference continues when your equipment is off, the
equipment is not the source of interference. If your equipment does appear to be the source of the
interference, you should try to correct the situation by using one or more of the following measures:
Relocate either the equipment or the electronic device that is being affected by the interference.
Utilize power outlets for the professional music equipment and the device being affected that are
on different branch (circuit breaker or fuse) circuits, or install AC line filters.
In the case of radio or TV interference, relocate the antenna or, if the antenna lead-in is 300 ohm
ribbon lead, change the lead-in the co-axial type cable.
If these corrective measures do not produce satisfactory results, please contact your authorized
Yamaha professional products dealer for suggestions and/or corrective measures.
If you cannot locate a franchised Yamaha professional products dealer in your general area contact
the professional products Service Department, Yamaha Music Corporation, 6600 Orangethorpe Ave.,
Buena Park, CA 90620, U.S.A.
If for any reason, you should need additional information relating to radio or TV interference, you
may find a booklet prepared by the Federal Communications Commission helpful:
"How to Identify and Resolve Radio -- TV Interference Problems". This booklet is available from
the U.S. Government Printing Office, Washington D.C. 20402 -- Stock No. 004-000-00345-4.
