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
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.
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 list of typical sound levels may assist you in recognising just how loud you have set the volume level.
