Caution
Failure
to
follow
these
recommendations
may
severely
reduce
the
amount
of
hearing
protection
provided
by
the
earplugs.
•
At
very
high
SPLs
(above
125
dB
SPL,
where
the
limit
to
attenuation
is
the
eartip
itself),
the
foam
eartips
provide
the
most
protection.
•
Eartips
fit
ear
canal
diameters
of
6-14
mm.
See
eartip
section
for
details.
•
The
following
applies
when
the
device
is
turned
off:
The
level
of
noise
entering
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
100
dBA
2.
The
NRR
is
25
decibels
(dB).
3.
The
level
of
noise
entering
the
ear
is
approximately
75
dBA.
Caution:
For
noise
environments
dominated
by
frequencies
below
500
Hz
the
(-weighted
environmental
noise
level
should
be
used.
Although
hearing
protectors
can
be
recommended
for
protection
against
the
harmful
effects
of
impulsive
noise,
the
Noise
Reduction
Rating
(NRR)
is
based
on
the
attenuation
of
continuous
noise
and
may
not
be
an
accurate
indicator
of
the
protection
attainable
against
impulsive
noise
such
as
gunfire.
•
Earplugs
must
be
fitted,
adjusted
and
maintained
to
the
manufacturer's
instructions
to
achieve
the
expected
attenua-
tion
and
hearing
protection.

•
Use
earplugs
at
all
times
on
noisy
surroundings
.
•
Earplugs
are

Further
information
should
be
sought
from
the

•
This
earplug
is
provided
with
level-dependent
attenuation.
The
wearer
should
check
correct
operation
before
use
.Ifdi
stortion
or
failure
is
detected,
the
wearer
should
refer
to
the
manufacturer's
advice
for
ma
i
ntenance.
Warning:
The
output
of
the
level-dependent
circuit
of
the
hearing
protector
may
exceed
the
daily
lim
it
sound
level.
Warning:
Performance
may
deteriorate
with
battery
usage
.
The
typical
period
of
continuous
use
that
can
be
expected
from
the

is
16
hours
.
•
To
determine
if
the
device
is
working

Changing
Eartips
The
eartip
that
is
most
comfortable
and
seals
the
ear
is
the
best
choice.
However,
the
eartip
must
seal
well
and
prevent
feedback
(whistling)
to
provide
proper
protection.
A
shallow
seal
may
reduce
the
expected
sound
amplification
and
hearing
protection.
•
Hold
device
firmly
and
pull
on
the
eartip
for
removal.
•
After
eartip
is
removed,
select
a
new
eartip
from
those
provided
in
the
package.
• If
lanyard

used,
push
the
loop
of
the
lanyard
against
the
body
of
the
