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
• 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 in recognising just how loud you have
set the volume level.
