equilateral triangle, is intended to alert you to the
presence of uninsulated “dangerous voltage” within
the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle
is intended to alert you to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.
Note to CATV system installer:
This reminder is provided to call the CATV system

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.
