Ensure that the headband is not bent or deformed, as this can impair the fit and reduce
sound attenuation or insulation.
The fitting of hygiene covers to the cushions may affect the acoustic performance of the
earmuffs.
For optimal protection, ear cushions should fit firmly around the head and form a good seal
around the ears.
Anything that interferes with the seal, such as long hair (pull back as far as possible), thick
or poorly fitting eyeglass temples, pencils, or caps, will reduce protection.
Put the earmuffs on before entering a noisy environment and leave them on until you are
no longer exposed to noise.
6 Using the earmuffs
These earmuffs conform to the size requirements stipulated in EN-352-1:2020 and are
suitable for the majority of users.
Protection against noise cannot be guaranteed if you do not observe the insulation speci-
fications listed in the "Technical data" section.
Putting on the earmuffs
Pull the two ear cups apart and fit the ear cushions over both ears.
The cushions should completely cover your ears and fit firmly around your head.
Ensure that the headband sits on top of your head. If necessary, adjust the ear cups by
moving them in or out of their holders to fit your head.
Ensure that the seal is sufficient to provide effective noise reduction.
7 Cleaning and maintenance
Important:
– If the following recommendations are not followed, both attenuation (insulation) and
function of the earmuffs may be impaired.
– Never use aggressive detergents, rubbing alcohol or other chemical solutions, as the-
se may damage the housing or cause the product to malfunction.
– Do not immerse the product in water.
Clean the outer surfaces of the earmuffs, headrest and ear cups regularly with mild soap
and lukewarm water or alcohol swabs. Leave to dry in the air.
Do not store the earmuffs at temperatures above 55 °C, such as behind a windshield or
window.
The earmuffs must be regularly inspected for cracked or worn parts and replaced as nee-
ded.
Store the earmuffs in a clean and dry plastic container (bag or box) when you are not using
them.
