WARNING:
1. Use this laboratory derived attenuation data for comparison purposes only. The amount
of protection afforded in field use often is significantly lower depending upon how the
protectors are fitted and worn.
2. Failure to follow all instructions could result in hearing loss or injury.
3. Failure to obtain a proper fit will reduce effectiveness of hearing protectors and could
result in hearing loss or injury.
4. Over protection can be dangerous. The wearer must be able to hear warning signals.
5. Wearers with hearing loss should exercise extreme caution.
6. It is the employer’s responsibility to ensure that the type of hearing protector and its
NRR rating is appropriate for the user in their particular workplace.
7. Failure to follow these warnings could result in serious injury or death.
8. Moldex earmuffs must only be used as part of a hearing conservation program that
complies with applicable local safety and health regulations.
INFORMATION REQUIRED BY EPA:
“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 92 dBA.
2) The NRR is 33 decibels (dB).
3) The level of noise entering the ear is approximately equal to [92 dB(A) -33] 59dB(A).”
CAUTION:
“For noise environments dominated by frequencies below 500 Hz the C-weighted
environmental noise level should be used. Improper fit of this device will reduce its
effectiveness in attenuating noise. Consult the enclosed instructions for proper fit. 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.”

MX-5/MX-6 SERIES INSTRUCTIONS FOR USE:
Earmuffs must be fitted and worn correctly to provide effective protection. Earmuffs and
their cushions may deteriorate with use and should be examined for cracking or other
deformations and replaced as necessary. Routinely wash with mild soap and water. The
foam liner should be allowed to air dry before reinserting into the earcups.
1) With headband over-the-head, pull the cups outward and position over your ears so that
they fully enclose the ear and seal tightly against the head.
2) Adjust the height of the cups until you have a tight and comfortable fit. For best results,
remove all hair from under the cushions.
3) Maintenance: Replace cushions and foam inserts at least twice a year for hygiene
and safety. For MX-5 order Part No. 6125 and for MX-6 order Part No. 6135.
For MX-6 only: Place the glossy side of the foam against the cup.

MX-7 SERIES INSTRUCTIONS FOR USE:
Cap Mounted Earmuffs must be fitted and worn correctly to provide effective protection.
Earmuffs and their cushions may deteriorate with use and should be examined for crack-
ing or other deformations and replaced as necessary. Routinely wash with mild soap
and water. The foam liner should be allowed to air dry before reinserting into the earcups.
1) Position top of cup below helmet. Helmet must rest level on head with brim straight
forward and be fitted correctly, per manufacturer’s instructions.
2) Press arm to snap against side of head. An audible click will be heard.
3) Adjust position of each cup on wire so both ears are completely and comfortably
sealed inside cup cushions. Cup must be sealed around the ear, without any
interference from any part of the helmet. If any part of the helmet, including the
suspension, contacts the cup or cushion, then readjust. If cup cannot be adjusted to
avoid contact with helmet, then hearing protection will be reduced and muffs must
not be worn.
4) For maximum hearing protection, there must be no interference between the cup
cushion sealing surface and wearer’s head. Pull hair back outside the cushion
sealing area and remove anything that interferes with the cushion seal. Any
interference with sealing area ( e.g. eyewear, respirator straps, etc. ) will signifi-
cantly reduce hearing protection. To minimize this, use the thinnest temples straps.
5) Do not bend or reshape the wires.
6) To remove, pull cup out until an audible click is heard.
7) Maintenance: Replace cushions and foam inserts at least twice a year for hygiene and
safety. MX-7 order Part No. 6140. Place the glossy side of the foam against the cup.
