IMPORTANT AUDIO SAFETY
Your hearing is very important to you and to us, so please take care when operating this equipment. It
is strongly recommended that you follow the listed guidelines in order to prevent possible damage to
or loss of hearing.
Establish a safe sound level
Over time your hearing will adapt to continuous loud sounds and will give the impression that the
volume has in fact been reduced. What seems normal to you may in fact be harmful. To guard against
this before your hearing adapts set the volume at a low level.
