IMPORTANT NOTES
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.
• Remember listening for prolonged period of time at high volume levels will
harm your hearing.
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 recognizing just how
loud you have set the volume level.
