JSP SONIS 1 Mode D'emploi

USE: When worn according to the User Instructions, this hearing protector helps reduce exposure to both continuous noises, such as noises from vehicles and aircraft, as well as very loud impulse noises, such as gunfire. It
is difficult to predict the required and/or actual hearing protection obtained during exposure to impulse noises. For gunfire, the weapon type, number of rounds fired, proper selection, fit and use of hearing protection, proper
care of hearing protection, and other variables will impact performance. If your hearing seems dulled or you hear a ringing or buzzing during or after any noise exposure (including gunfire), or for any other reason you suspect
a hearing problem, your hearing may be at risk.
IMPORTANT: For correct fit, ear cushions should seal firmly against the head. Anything that interferes with the seal such as long hair (pull back to the extent possible), thick or poorly fitting eyeglass temples, pencils or caps
will lessen the earmuff's effectiveness. Do not bend and reshape the headband, as this will cause a loose fit and sound leakage.
NOISE REDUCTION RATING (NRR): The EPA (Environmental Protection Agency) has selected the NRR as the measure of a hearing protector's noise-reducing capabilities. JSP makes no warranties to the suitability of
NRR as a measure of actual protection from any noise level since such protection depends on the sound level (loudness), how long you listen to the loud sound, and how well you fit the earmuff on your ears. Although hearing
protectors can be recommended for protection against harmful effects of impulse noise, the Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection
attainable against impulse noise such as gunfire. Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in fit and wearing time. JSP recommends reducing the NRR
by 50% for estimating the average amount of noise reduction provided. Improper fit of this device will reduce its effectiveness in attenuating noise. 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 (achieved under laboratory conditions): 1. The environmental noise level as measured at the ear is 92 dBA. 2. The NRR of the ear defender is 30 decibels (dB). 3. The level of noise entering the ear is
approximately equal to 62 dB(A). The U.S. Environmental Protection Agency (EPA) and the World Health Organization (WHO) recommend a level below 70dBA over 24-hours to be a safe level.

CAUTION: For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used.
BEFORE USE: Check cushion for damage. Check inner foam is present inside the cup. Check the plate is correctly attached. IMPORTANT! For optimum performance please check that the Cushion part is tucked under all 6 tabs on the
Plate part, as shown in (Image 2). If plate/cushion has been replaced, check that the elasticated O-ring is present (Image 3). Prior to fitting inspect the product to ensure it is not damaged. If this is discovered dispose of immediately and
obtain a new pair.
FITTING INSTRUCTIONS FOR HEAD-BANDED Sonis : 1. Pull cups to their maximum extension on the headband (Image 4). 2. Place the headband on top of the head (Image 5) and apply pressure to the headband to
®
keep it in place. Slide each cup upwards until the cushion encloses the ear and the seal is not broken by the ear (Image 6). Once the ear muff is fitted push both cups in towards the head to compress the cushion and improve
fitment and seal further (Image 7). 3. Allow 2 minutes for the cushions to warm and form to the users head. 4. (Image 8) shows the product correctly fitted.
FITTING INSTRUCTIONS FOR HELMET-MOUNTED Sonis : These earmuffs should be fitted to, and used only with, the: EVO
®
the side of the hard hat until it clicks into place (Image 9). 2. For adequate protection ensure the hard hat is fitted and adjusted to the size of the user's head. 3. Pull cups to their maximum extension and set the arms into the
stand by position (Image 10). 4. Press the wire bands inwards until you hear a click on both sides indicating a firm seal (Image 11). 5. Adjust the cups by sliding up or down until they form a seal around the ears (Image 12).
6. Once the ear muff is fitted push both cups in towards the head to compress the cushion and improve fitment and seal further (Image 13). 7. Allow 2 minutes for the cushions to warm and form to the users head. 8. (Image
14) shows the product correctly fitted. When not in use, place the hearing protectors in the off position by rotating the arms backwards (90 degrees) and close the arms by pressing them against the helmet.
CLEANING INSTRUCTIONS: The ear-muff may be cleaned with the use of soap and warm water and dried with a soft cloth. JSP cleaning wipes may also be used or an antibacterial wet wipe. Do not allow the cushions
or the inner foam to become wet. If these parts become wet they should be removed and replaced. The ear-muff should not be cleaned with abrasive substances or solvents and must not be stored in direct sunlight or in
contact with any solvents. This product may be adversely affected by certain chemical substances. Ear-muffs, and in particular cushions, may deteriorate with use and should be examined at frequent intervals for cracking
and leakage, for example, and replaced when required. Replace the worn or damaged cushions and insert with the new pair from the appropriate Hygiene Kit.
