WARNING!
This hearing protector is intended to protect the wearer from
hazardous noise levels when fitted in accordance with this
user instruction. Any other use is not intended and therefore
not permitted. It is important that the instructions for use are
followed. Failure to do so could result in a drastic decrease
of the noise attenuation and may lead to serious injury.
Read these user instructions carefully!
• The hearing protector must be worn at all times in noisy
environments to provide full protection! Only 100% wear
time provides full protection.
• Do not remove the headset to change settings in a noisy
environment. Use menu system with guide voice while
wearing the headset.
• The audibility of warning signals at a specific workplace
may be impaired due to over-protection, when using
a hearing protector with too high a noise attenuation
performance in relation to the noise environment.
• When using hearing protection with entertainment audio
features, remember to adjust the volume when working
in noisy environments so that any warning signals etc.
can be heard.
• In some individuals, excessive sound pressure from
earphones and headphones may cause hearing loss.

• The hearing protector's noise attenuating properties can
dramatically decrease when used with, for example, thick
eyeglass 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 it shows any signs of
cracking or damage.
• The earmuffs shall be regularly inspected for serviceability.

capacity is sufficient throughout a critical task. Battery
capacity may deteriorate over time.
• Ensure matching configuration by testing communication
before commencing critical task.
• Note, on communication radio, only one unit can transmit
at the same time. A unit can not receive a message while
