Caution
Failure
to
follow
these
recommendations
may
severely
reduce
the
amount
of
hearing
protection
provided
by
the
earplugs.
•

standard
of

•
At
very
high
SPLs
(above
125
dB
SPL,
where
the
limit
to
attenuation
is
the
eart
ip
itself),
the
foam
eartips
provide
the
most
protection.
•
The
following
applies
when
the
device
is
turned
off
or
the
battery
is
drained
:
The
level
of
noise
ente
r
ing
a
person's
ear,
when
a
hearing
protector
is
worn
as
directed,
is
closely
approximated
by
the
difference
between
the
A-weighted
environmental
noise
level
and
the
NRR.
Example
1.
The
environmental
noise
level
as
measured
at
the
ear
is
92
dBA.
2.
The
NRR
is
25
decibels
(dB).
3.
The
level
of
noise
entering
the
ear
is
approximately
equal
to
67
dBA.
Caution:
For
noise
environments
dominated
by
frequencies
be
l
ow
500
Hz
the
C
-weighted
environ-
mental
noise
level
should
be
used.
Although
hearing
pr
otectors
can
be
recommended
for
protection
against
the
harmful
effeds
of
impulsive
noise,
the
Noise
Reduction
Rating
(NRR)
is
based
on
the
attenuation
of
continuous
noise
and
may

•
Earplugs
must
be
fitted,
adjusted
and
maintained
to
the
manufacturer's
instructions
to
achieve
the
expected
attenuation
and
hearing
protection.
•
Use
earplugs
at
all
times
in
noisy
surroundings.
•
Make
certain
that
the
earplugs
provide
adequate
protection
for
the
noisy
environment.
•
Earplugs
are
reusable.
Regularly
inspect
the
earplugs
to
assure
their
continued
serviceability.
•
Connecting

should
not
be
used
where
there
is
a
risk
that
the
connecting
cord
can
be
caught
up
during
use.
•
This

may
be
adversely
affected
by
certain
chemical
substances.
Further
information
should
be
sought
from
the
manufacturer.
•
This
earplug
is
provided
with
level-dependent
attenuation.
The
wearer
should
check
correct
operation
before
use.
If
distortion
or
failure
is
detected,
the
wearer
should
refer
to
the
manufacturer's
advice
for
maintenance
and
replacement
of
the
battery.
Warning:
The
output
of
the
level-dependent
circuit
of
the
hearing
protector
may
exceed
the
daily
limit
sound
level.
•
To
determine
if
the
device
is
working,
insert
a
battery,
cup
the
device
in
your
hand
and
listen
for
acoustic
feedback
(squeal}.
If

is
present,
the
