FCC INFORMATION (for US customers only)
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 equipment 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:
Relocate either this product or the device that is being 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.
