8 CAUTIONS
Only use compatible QuietOn eartips. Do not insert the earplug directly into the ear without a
correctly 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 e ect 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 ATTENUATION".
The performance of active noise cancelling earplugs may be adversely a ected when sustained
oscillation (whistling or instability) is perceived. If refitting the earplugs does not overcome this, you
should contact us.
