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
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 that be harmful. To guard against this BEFORE YOUR HEARING
ADAPTS 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 maybe too loud.
Once your have established a comfortable listening level, DO NOT INCREASE THE SOUND
LEVEL FURTHER.
The following list of typical sound levels may assist you in recognising just how loud you have set
the volume level.
