USER GUIDE
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.
