Precautions
Listening
caution
Do
not play your
headphones
at
a high
volume.
Hearing experts advise against continuous extend-
ed
play.
If
you
experience a ringing
in
your ears,
reduce
volume
or discontinue use.
Do
not use while operating a motorized vehicle.
It
may
create
a
traffic
hazard and
is illegal in
many
areas.
You
should use extreme caution or temporarily
discontinue use
in
potentially
hazardous
situa-
tions.
Sound can be
deceiving.
Over
time your hearing
"comfort level"
adapts
to higher
volumes
of
sound.
So
what sounds "normal"
can
actually be loud
and
harmful
to
your
hearing.
Guard
against
this
by setting your equipment
at
a
safe level
BEFORE
your hearing adapts.
To
establish a safe
level:
•Start your volume
control at
a low
setting.
•Slowly
increase the
sound
until
you can hear
it
comfortably and
clearly,
and without
distortion.
Once
you have
established
a comfortable sound
level:
•Set the
dial
and leave
it
there.
Notes on use
The
battery
is
used by
the noise cancelling func-
tion and,
even
without
it,
the unit functions
as a
normal pair
of
headphones.
This noise cancelling function mainly reduces low
frequency
sounds below 1500
Hz. For
this
reason,
sounds
with
higher frequency
portions
remain
rela-
tively intact.
The noise cancelling function acts
to
make
a
qui-
eter listening
environment
in
places with a
lot of
noise.
Turn the function
off
when
listening
in
places that are already
quiet.
Noise
may
occur
due
to
dirt
on
the plug.
Clean
the
plug with a soft dry cloth
if
this
occurs.
Product Service
