Warning
This hearing protector is provided with active noise reduction. The wearer should
check correct operation before use. If distortion or failure is detected, the wearer
should refer to the manufacturer’s advice for maintenance and replacement of the
battery.
Performance may deteriorate with battery usage. The typical period of continuous use
that can be expected from the hearing protector is 12 hours.
The hearing protector is provided with electrical audio input and output to allow for
two-way communications. The wearer should check correct operation before use. If
distortion or failure is detected, the wearer should refer to the manufacturer’s advice.
The performance of the active noise reduction may be adversely affected when
sustained oscillation (whistling or instability) is perceived. If refitting the hearing
protector or replacement of the batteries does not overcome this malfunction, the
wearer should contact the supplier or manufacturer
The output of the electrical audio circuit of this hearing protector may exceed the daily
limit sound level and/or upper action level.
The audibility of ambient warning signals at a specific workplace transmitted by sound
generated outside the hearing protector may be impaired.
Protection afforded by the DANR system will be severely impaired if:
•
The earmuffs and earplugs are not fitted, adjusted, and maintained
manufacturer’s instructions.
•
The earmuffs and earplugs are not regularly inspected for serviceability.
•
The earmuffs and earplugs are not worn at all times in noisy surroundings.
Earmuffs, and in particular cushions, may deteriorate with use and should be
examined at frequent intervals for cracking and leakage, for example.
The fitting of hygiene covers to the cushions may affect the acoustic performance of
the earmuffs.
This product may be adversely affected by certain chemical substances. Further
information should be sought from the manufacturer.
See supplemental component manuals for additional warnings and cautionary
