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.
