ACE „Shh...!" Earmuffs
User manual – EN
Warning: Before use, the hearing protector must be adjusted
as described in the manual and worn in noise areas without
interruption. Earmuffs and especially the sealing cushions can wear
out with use and should therefore be checked frequently for signs
of, for example, cracks and leaks. Also check whether the hearing
protector needs servicing. Wrapping the sealing cushions with
hygiene covers may affect the acoustic performance of the earmuff.
Failure to comply with the above points may result in a significant
reduction in the protective effect.
This earmuff shall only be worn by children of at least five years. At
this age the bone structure of the children`s heads will be so solid
and strong that the risk of deformations is eliminated.
This earmuff is suitable for children with a head height up to
130mm only.
Adults should check and make sure that the earmuff is worn correctly
an continuously by the child.
