SAFETY INSTRUCTIONS

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

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.
