CAUTION!
In noisy environments, the earmuffs must be worn in the working position at all times.
B 5: Stand-by position. Pull the ear-muff away from the ear until it locks into the stand-by position.
B 6: Parked Position. First lift the cups to the stand-by position, and then rotate them back to the next fixed
position. In this position, the cushion does not get damaged or dirty and the cups can dry out on the inside.
NOTE: Do not press the cups onto the helmet shell as this will lock the spring in the ear-muff arm and damage the
attachment slots on the side of the helmet.
B 7: Storage Position. When the helmet is not in use, lower the ear-muffs and press them inward.
Note: These helmet-mounted hearing protectors are only approved for use with MSA slotted caps.
STORAGE
When the hearing protector is not in use, store it in such a way that the headband is not stretched and the
cushions are not compressed. Keep the ear-muffs dry and clean, store them at normal room temperature and do
not place them in direct sunlight.
CAUTION!
If storage recommendations are not followed, the protection afforded by the hearing protector may be
severely impaired.
MAINTENANCE
Clean and disinfect the cups, cushions and inserts with mild soap and water only. Ear muffs and cushions in
particular may deteriorate with use. Examine at frequent intervals for cracking and leakage, for example at the
start of every working shift. Replace damaged or worn ear muffs or cushions.
HYGIENE KITS The cushions and inserts are replaceable. Always replace worn or damaged parts. Remove the
cushion by pulling it straight out (refer to illustration C1 at beginning of this instruction manual). Replace the old
cushion and insert with new ones from the hygiene kit (refer to illustration C2 at beginning of this instruction
manual). If the ear muff is used regularly, replace the hygiene kit at least twice a year to ensure that the noise
attenuation performance is maintained.
Note: Use only hygiene kits (cushions and inserts) from MSA.

WARRANTY
The product is guaranteed for one year from date of purchase against defects in material or workmanship. This
guarantee does not extend to damage caused by product misuse, abuse or unauthorized modifications. To make a
claim, please contact the source of purchase.
TESTING AND APPROVALS
The Noise Reduction Rating (NRR) is third-party certified in accordance with ANSI S3.19-1974. It also meets CSA
Class A.
Use Limitations
The level of noise entering a person's ear, when hearing protection is worn as directed, is closely approximated by
the difference between the A-weighted environmental noise level and the NRR.
Example: The environmental noise level as measured at the ear is 92 dB(A). The NRR is (24) decibels (dB). The
level of noise entering the ear is approximately equal to 68dB(A) [92 – 24 dB(A)].
CAUTION!
For noise environments dominated by frequencies below 500 Hz the C-weighted environmental noise level
should be used.
The EPA has selected the NRR as a measure of a hearing protector's noise reducing capabilities. There is no
warranty as to the suitability of the NRR as a measure of the actual workplace protection since such protection is
