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:
ESTABLISHA 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 recognizing just how loud you have set the volume level .
