Tips & tricks

  1. The user is irritated by the cord rubbing on clothing.
  2. The custom hearing protection* no longer allows communication.
  3. Is it possible to wear headphones in addition to the protections?
  4. Is it necessary to insert the 2 protections when a person is deaf in one ear?
  5. Can the filter and the canal in which the filter is located be cleaned with a "gas duster"?
  6. The user has difficulty in telling the right protection from the left protection.

2. The custom hearing protection* no longer allows communication.

If the acoustic filter is blocked or not properly cleaned ..., it will no longer allow vocal frequencies to pass through it. To perform a check use the bulb from the CLEANIL PRO kit, taking care to position the nozzle in the drilling of the protection located on the “handle side”. By applying pressure, it is easy to check passage of air.
If the filter is blocked, a maintenance operation with the CLEANIL cleaning tablets may in some cases dissolve the impurities (refer to the recommendations for use of the CLEANIL cleaning tablets) and make communication easier. If air does not circulate, contact COTRAL International or the prevention technician.
* In view of the wide variety of expressions used to denote moulded plugs, earplugs or anti-noise plugs, COTRAL International refers to its protections as "custom hearing protections". If you are looking for moulded protections, moulded hearing protections, anti-noise hearing aids or furthermore personalized hearing protections, our products will meet your needs.
