IMPORTANT NOTICE
FOR THE UNITED KINGDOM
This series of Yamaha professional music equipment uses frequencies Connecting the Plug and Cord
that appear in the radio frequency range and if installed in the im-
mediate proximity of some types of audio or video devices (within
three meters), interference may occur. This series of Yamaha pro-
fessional music equipment has 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
IMPORTANT. The wires in this mains lead are
coloured in accordance with the following code:
the FCC rules. These rules are designed to provide a reasonable BLUE NEUTRAL
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 BROWN : LIVE
other electronic devices, verification can be made by turning your
professional music equipment off and on. If the interference con-
tinues 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. Utitize 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 to
a co-axial type cable.
