If there is any drainage from your ear or you have an ear infection, consult with your physician before
wearing earplugs. Failure to do so may result in hearing loss or injury.
The sound attenuation caused by the device can create a risk in situations where it is important to hear
environmental sounds and warning alarms, for example, road traffic or warning sirens on a construction site.
Note that alarm sounds will sound different when wearing the earplugs.
Local laws may restrict the use of QuietOn in traffic. Always obey local laws.
Do not use the earplugs if they produce excessively loud audio tone. If this occurs while the mesh is clean,
the device may be broken and should be returned to the seller. This should not be confused with the beep
sound that is created momentarily when the plugs are inserted into the ear. Do not use the earplugs if the
beeping sound is continuous.
The device contains small parts that may present a choking hazard to small children and animals. The device
attached eartip.
When used according to the User Instructions, this hearing protector helps reduce exposure to noises, such
as industrial noises and noises from vehicles and aircraft. If your hearing seems dulled or you hear a ringing
or buzzing during or after any noise exposure, your hearing may be at risk and you should move away from
such noise to protect your ears.
Notice is that if the battery is empty, there is an effect to device's performance and active noise cancelling
is not working. The attenuation is then at passive level. Do check device functionality according the “Testing”
section at the beginning of this manual. When using the device for the hearing protection purpose, ensure
that passive protection is enough for your purposes. See the tables in chapter “LABORATORY ATTENUA-
TION”.
The performance of active noise cancelling earplugs may be adversely affected when sustained oscillation
(whistling or instability) is perceived. If refitting the earplugs does not overcome this, you should contact us.
