Uvex aXess one Installation instructions

USER INSTRUCTION
uvex aXess one:
Active earmuffs with Bluetooth® function for communication, audio streaming and a listening through
function called RAL (Real Active Listening). The uvex aXess one limits the sound pressure level of the
audio signal for entertainment purposes to 82dB(A). The perceptibility of warning signals at certain
workplaces may be impaired when using the sound reproduction system.
The uvex aXess one is equipped with foldable headband and continuous length adjustment.
This is a category III, harmful noise, PPE product.
Warning:
This hearing protection serves to protect against harmful noise when used in accordance with these
instructions for use. Wear the hearing protection during the entire time you are in the noise area. The
hearing protection must be checked before each use. Sealing pads may show signs of age, look for
defects or cracks and check the flexibility of the sealing pads. If damaged, do not use the hearing
protection. Replace sealing cushions twice a year to maintain seal, hygiene and comfort. Brush long
hair to the side and remove jewelry or other objects that interfere with the acoustic seal. The fitting of
hygiene covers to the cushions may affect the acoustic performance.
This earmuff is equipped with a communication device. The user should check for proper operation
before use. If distortion or failure is detected, the user should follow the manufacturer's
recommendations for maintenance. Warning. The output sound pressure level of the communication
device of this hearing protector may exceed the daily limit. This earmuff is equipped with level-
dependent sound attenuation. The user should verify proper operation before use. If battery
displacement or failure is detected, the user should follow the manufacturer's advice for battery
maintenance and replacement. Warning: performance may deteriorate due to battery wear. The typical
duration of continuous use that can be expected from the earmuff battery is 50 hours. Warning: Sound
output from the sound regeneration circuitry may exceed the external sound level. Failure to follow the
instructions may adversely affect the effectiveness of the earmuffs, resulting in hearing damage.

Charge the battery:
Charge the battery before using it for the first time. The entire system is switched off during the
charging process. The battery is permanently installed and cannot be replaced. During the charging
process, the LED display lights up red; when fully charged, the LED display changes to green. Never
leave the uvex aXess one unattended during charging.

Press and hold the button for 5 seconds until the LED status indicator flashes RED/BLUE and you
hear "power on". The automatic pairing mode starts and "pairing" sounds. The uvex aXess one
appears in the Bluetooth menu on the external device, now select and activate it, now "connected"
sounds. The hearing protector is now connected to the Bluetooth device.
Bluetooth pairing second device:
Um ein Zweites Gerät zu koppeln, ist einmalig folgender Schritt nötig, deaktivieren Sie Bluetooth am
erstem Gerät, er ertönt „disconnected“. Bluetooth am zweiten Gerät aktivieren, es erscheint die uvex
aXesss one am zweiten Gerät, diese nun auswählen und aktivieren. Nun kann am ersten Gerät wieder
Bluetooth aktiviert werden und auch hier die uvex aXess one auswählen. Nun sind beide Geräte mit
der uvex aXess one verbunden.
Bluetooth disconnect/delete connections:
Press and hold the key and the key together for 3 seconds. To clear the memory completely,
press and hold both keys for 5 seconds.
Automatic shutdown without pairing: 5min
Real Active Listening RAL:
The RAL function is a stand-alone function. To ensure that the ambient sounds are permanently
perceived, there is no automatic switch-off. Note, RAL always requires a switch-off by the user.
The RAL function is equipped with a level limiter that cuts off the maximum output level at 82dB. The
volume below 82dB can be adjusted in 5 steps. This allows a slight amplification for soft sounds.

Information required by E.P.A. (US)
The level of noise entering a person’s ear, when hearing protectors are worn as directed, is closely
approximated by the difference between the A-weighted environmental noise level and the NRR.
For example:
1. The environmental noise level as measured at the ear is 92 dBA.
2. The NRR is 29 decibels (dB).
3. The level of noise entering the ear is approximately equal to 63 dBA.
Caution: For noise environments dominated by frequencies below 500 Hz, the C-weighted
environmental noise level should be used. Improper fit of this device will reduce its effectiveness in
attenuating noise. Consult the enclosed instructions for proper fit. Although hearing protectors can be
recommended for protection against the harmful effects of impulsive 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 impulsive noise such as gunfire. Constant or repetitive exposure to
impulsive noise may lead to serious injury, including temporary or permanent deafness. The Noise
Reduction Rating (NRR) calculated from the attenuation data is 29 dB. Earplugs must be fitted to
attenuate noise effectively. Refer to instructions.
FCC Compliance Statement
