IMPORTANT SAFEGUARDS
Hearing is a one of our most valuable senses, so please take care of yours when using
this player. We strongly advise you to adhere to the following instructions so as to
guard against possible injuries or loss of hearing:
ESTABLISH A “SAFE” SOUND LEVEL
•
Over time, your hearing will get used to continually listening to loud music, which
will give you the impression the volume has been turned down. But a sound level
that seems normal to you may in fact be harmful. To protect yourself from this risk,
adjust the volume to a sufficiently low level,
BEFORE YOUR HEARING HAS TO
ADAPT
.
•
Increase the level little by little until you can hear comfortably and clearly without
any distortion.
•
Hearing damage has a cumulative effect and is irreversible.
•
If you have a "ringing sound in your ears" or feel discomfort when listening, the
volume is set too high.
When you have reached a comfortable listening volume,
DO NOT INCREASE THE
SOUND LEVEL ANYMORE.
Please find below a short list of common sound levels which may help you evaluate
your volume setting.
