Important Notes
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 or loss of hearing:
ESTABLISH A SAFE SOUND LEVEL
BEFORE YOUR HEARING ADAPTS
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
set the
volume at a low level.
Slowly increase the level until you can hear comfortably and clearly and without
distortion.
Damage to your hearing is accumulative and is irreversible.
Any ringing or discomfort in the ears indicates that the volume is too loud.
Once you have established a comfortable listening level, DO NOT INCREASE THE
SOUND LEVEL FURTHER.
THE FOLLOWING NOISE CAN BE HARMFUL UNDER CONSTANT EXPOSURE
PERMANENT LOSS OF HEARING
