Important: This product will operate within a temperature range of -20
˚
F to +110
˚
F and within a relative humidity range of 0% to 98%, it
can not be submerged. Submersion will permanently damage the circuit and void the warranty. The operation of cell phones within 12.5m
may cause static.
Example:
1. The environmental noise level as measured at the ear is 93 dBA
2. The NRR is 27 decibels (dB)
3. The level of noise entering the ear is approximately equal to 64.5 dBA
CAUTION
For noise environment dominated by frequencies below 500Hz, the
C-weighted environmental noise level should be used. Improper
fit of this device will reduce it’s effectiveness in attenuating noise.
Although hearing protectors can be recommended for protection
against the harmful effects of impulse noise, the Noise Reduction
Rating is based on the attenuation of continuous noise and may not
be an accurate indicator of the protection attainable against impul-
sive noise, such as gunfire.
Tested to ANSI Ss. 19-1974 (R 1979) section 4 by certified laborato-
ry Engineering Dynamics incorporated Report No. T-Power Aisle-2
INFORMATION REQUIRED BY EPA:
The level of noise entering a person’s ear, when Hearing Protector is
worn as directed, is closely approximated by the difference between
the A-weighted environmental noise and the NRR.
Instructions For Use:
When worn properly and given adequate care, this sound muffler
provides excellent protection by filtering out high frequency
noise caused by machinery, motors, saws, and gunfire.
1. Extend headband to maximum “open” position and place the
cups over the ears with the headband passing over the head.
2. Settle the headband in position on the head while adjusting the
fit of the ear cups up or down until they feel comfortable and
the headband rests on the top of the head to support the muffs.
3. Make sure that the headband is evenly adjusted, left to right.
The ear cushions should be a snug fit against the head.
4. Make sure to get as little hair as possible between the ear
cushions and your head.

ANSI S12.42, (ANSI S3.19) Physical Method.
3.0 Test Results –
The results of the hearing protector acoustical tests and
the Noise Reduction Rating (NRR) calculations are presented in Table 3.1.
In accordance with 40CFR PART 211 – Product Noise Labeling, “Spectral
uncertainty. Possible variation in exposure to the noise spectra in the workplace.
(To avoid the under protection that would result from these variations relative to
the assumed ``Pink Noise’’ used to determine the NRR, an extra three decibel
reduction is included when computing the NRR.) “ The NRR rating in accordance
with 40CFR211 is shown in Table 3.1. Table 3.1: Model (30285, 30286, 30287,

A wider range indicates
greater variability in
the fit of that HPD.
Smaller ranges indicate
more consistency of
fit. For example, ear-
muffs will usually have
a tighter fitting range
than earplugs, and may
have a smaller NRR
range.
Purchasers can be
referred to additional
training material found
on the manufacturer’s
