SAFETY PRECAUTIONS
Selecting fine audio equipment such as the unit you've just
purchased is only the first step to your musical enjoyment.
Now it's time to consider how you can maximize the fun and
the safety of your new equipment. We want you to get the
most out of your equipment by playing it at a safe level
without affecting your hearing. Sound can be very harmful.
Over time your hearing "comfort level" adapts to higher
volume of sound. What sounds "normal" can actually be loud
and harmful to your hearing. Therefore, please guard against
this by setting your equipment at a safe level before your
hearing adapts. To establish a safe level, you can start your
volume control at a low setting, then slowly increase the sound
until you can hear it comfortably and clearly. If used wisely,
your new sound equipment will provide you a pleasant
experience in music. Since hearing damage from loud noise
is often undetectable until it is too late, we recommend you
avoid prolonged exposure to excessive noise. The following
noises can be dangerous under constant exposure. Therefore,
please be cautious with the dB level when playing your new
equipment.
