Item number: 10029300, 10029301, 10029302, 10029303
Congratulations on purchasing these passive earmuffs.
This is a multi-purpose hearing protector, suitable for use in leisure and sports. However,
please read carefully the following instructions in order to get the best functionality from this
product.
Thanks to the collapsible plastic headband you can wear your earmuffs over the top of the
head. You can easily replace the two attenuation cushions, one on each cup. It is recommend-
ed to replace at least twice a year.
Instruction for use:
1. Slide out the shells and place the hearing protector over your ears so the ear cushions
enclose the ears completely and fit . Snuggle against the head. Brush aside hair around
the ears.
2. Adjust the height of the cups for a comfortable fit while holding headband flat against
your head.
3. The headband should lie across the top of the head.
Example:
The environmental noise level as measured at the ear is 100 dB.
The SNR is 35 decibels (dB).
The level of noise entering the ear is approximately equal to 65 dB.
Attention:
Wear the hearing protector 100 % of the time you spend in noisy environments.
Clean the outside of the earmuffs with soap and warm water.
Do not store the earmuffs in temperatures exceeding 55 °C.
