FCC INFORMATION

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.

We Want You Listening For A Lifetime
