Approved helmet combinations EN 352-3

These earmuffs should be fitted to, and used only with the following industrial safety helmets. For the latest list of approved helmet combinations please see our website: www.hellbergsafety.com

Certification and Monitoring: PZT GmbH, Bismarck Strasse 264 B, 26389 Wilhelmshaven, Germany, Notified Body: 1974, Notified by ZLSC9
English is the language examined by Notified Body. English has interpretive precedence.

USER MANUAL
All the hearing protectors which are included in this instruction sheet are equipped with a thermoplastic headband or spring-arms, or stainless-steel neckband and foam  plastic filled cushions. This hearing protector is intended to protect the wearer from hazardous noise levels when fitted in accordance with these user instructions. Any other  uses are not intended and therefore not allowed.
Hereby, Hellberg Safety AB, declares that the hearing protector Secure is in compliance with PPE regulation EU 2016/425 and other appropriate directives to fulfil the  requirements of CE marking. The full text of the EU declaration of conformity is available at the following internet address: www.hellbergsafety.com/declarationofconformity.
For manufacturing date, see the date clock on the inside of the ear cup. Expected lifetime of product is 5 years.

Warning!
It is important that the instructions for use are followed. Failure to do so could result in a drastic reduction in the noise attenuation and may lead to serious injury.

Carefully read these user instructions!

• The hearing protector must be used at all times in noisy environments to provide the full  protection effect! Only 100% wear time provides full protection.
• The audibility of warning signals at a specific workplace may be impaired if over protected, when using a hearing protector with a too high noise attenuation performance  in relation to the noise environment.
• Certain chemical substances can have a destructive effect on this product. More information is available from the manufacturer.
• Ensure that the hearing protectors are regularly inspected for serviceability.
• The hearing protector’s noise attenuating properties can dramatically decrease with usage of for example thick spectacle frames, ski masks/balaclavas, etc.
• Use of perspiration/hygienic protection over the sealing rings can reduce the hearing protector’s noise attenuation properties.
• Earmuffs, and in particular cushions, may deteriorate with use and should be examined at frequent intervals for cracking and leakage.
• Immediately discard the product if showing signs of cracks or damage.
• Hygiene kit should be changed at least twice per year. Make sure you choose the correct hygiene kit for your hearing protector.
• Clean the product with mild soap. You must be sure that the detergent you use does not irritate the skin. Do not dip the product in water.
• The hearing protector must be stored in a dry and clean environment out of direct sun light, e.g. in its original packaging.

Fitting & adjustment (A)

Brush away all hair from the ears and place the hearing protectors over the ears so that they fit comfortably and snugly. Ensure that the ears are completely enclosed by the  hearing protectors and that you have even pressure around the ears.
Headband (A1)
Adjust the headband size so that it rests lightly against the crown of your head.
Neckband (A2)
Adjust the protector to its largest size and put it on. Now adjust the headband strap so that the protector rests lightly on your head.
Helmet/Cap mount (A3)
Push the hearing protectors helmet attachment into the helmet slot until it locks into position.
Place the hearing protectors over the ears and press inwards until you hear a click. Adjust the hearing protectors and helmet so that they fit comfortably on your head.
Foldable (A4)
Fold out the headband by pressing the cups outwards. The headband is now in its largest size. Put the headband on your head and adjust the size so that it rests lightly against the crown of your head (A1). To fold up the headband, adjust it to its largest size and press the cups inwards so that they fold into the headband.

Change of hygiene kit (B)

1. Remove the old sound absorbing foam and insert the new.
2. Pull off the old ear cushion.
3. Centre the new ear cushion over the hole.
4. Press with a finger along the outside of the ear cushion until it attaches all around the edges.
5. Pull off the old head cushion and insert the new.

Information required by E.P.A. (US)
The level of noise entering a person’s ear, when a hearing protector 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 dbA. The NRR is 25 decibels (dB).The level of noise entering the ear is approximately equal to 67 db.
Caution. For noise environments dominated by frequencies below 500 Hz the C-weighted environmental noise level shall be used.
Warning. Improper fit of this device will reduce its effectiveness in attenuating noise. Although hearing protectors can be recommended for protection against the harmful  effects of impulse noise, the noise reduction rating (NRR) is based on the attenuation of continuous noise and may not be accurate indicator of the protection attainable  against impulse noise such as gunfire.
