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 pre vent possible damage or loss of hearing:
ESTABLISH A SAFE SOUND LEVEL
• Over time you r hearing will adapt to conti nuous loud sounds and will give the
impression that the volume has in fact been reduced. What seems normal to
you may in fa ct b e har mful. To gu ard against this BEFORE YOUR HEARING
ADAPTS set the volume at a low level.
• Slowly increase the level until yo u can hea r comfor tably and clearly and without
disto rtion.
• Damage to your hearing is accumulative and i s irreversible.
