tion with regard to proper grounding of the mast and
supporting structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding conductors,
location of antenna discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode.

We Want You Listening For A Lifetime
YAMAHA and the Electronic Industries Association’s Consumer
Electronics Group want you to get the most out of your equip-
ment by playing it at a safe level. One that lets the sound come
through loud and clear without annoying blaring or distortion –
and, most importantly, without affecting your sensitive hearing.
Since hearing damage from loud sounds is often
undetectable until it is too late, YAMAHA and the
Electronic Industries Association’s Consumer
Electronics Group recommend you to avoid
prolonged exposure from excessive volume levels.
Compliance with FCC regulations does not guarantee
that interference will not occur in all installations. If this
product is found to be the source of interference, which
can be determined by turning the unit “OFF” and “ON”,
please try to eliminate the problem by using one of the
following measures:

affected by the interference.
Utilize power outlets that are on different branch (circuit
breaker or fuse) circuits or install AC line filter/s.
In the case of radio or TV interference, relocate/reorient
the antenna. If the antenna lead-in is 300 ohm ribbon
lead, change the lead-in to coaxial type cable.

tory results, please contact the local retailer authorized
