ISOtunes LINK AWARE Bedienungsanleitung Seite 16

headphones are worn as directed, is closely approximated by the difference
between the A-weighted environmental noise level and the Noise Reduc-
tion Rating (NRR). Improper fit of this device will reduce its effectiveness in
attenuating noise. Consult the enclosed instructions for proper fitting.
A1: Frequency (Hz)
A2: Mean Attenuation (dB)
A3: Standard Deviation (dB)
Example:
1. The surrounding noise level measured at the ear is 100 dB.
2. The NRR of ISOtunes® LINK Aware is 25 dB.
3. The noise level entering the ear is approximately equal to 75dB.
Please note that the 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.
EN 352
This product is certified according to the product standards EN 352-1:2002,
EN 352-4:2001, EN 352-6:2002, and EN 352-8:2008.
Haven Technologies hereby declares that IT-35 ISOtunes LINK Aware
EN 352 conforms to the regulation (EU) 2016/425 and the directive RED
2014/53/EU which can be accessed at
www.ISOtunes.co.uk/EU-declaration-of-conformity.
B1: Frequency (Hz)
B2: Mean Attenuation (dB)
B3: Standard Deviation (dB)
B4: Assumed Protection Value (APV) (dB)
B5:
H = Hearing protection estimation for high frequency sounds
(f ≥ 2000Hz)
M = Hearing protection estimation for medium frequency sounds
(500 Hz < f < 2000Hz)
L = Hearing protection estimation for low frequency sounds
(f ≤ 500Hz)
Criterion level is the sound pressure level in dB(A) of the noise environment
resulting in 85 dB(A) effective to the ear while wearing hearing protectors.
Three different criterion levels are defined related to the frequency content
of the noies.
C1: H = criterion level for high-frequency noise
C2: M = criterion level for medium-frequency noise
C3: L= criterion level for low-frequency noise
SafeMax™ Technology
ISOtunes® LINK Aware incorporates SafeMax™ Technology, therefore
its volume output has been limited to 85 decibels (IT-34) and 79 decibels
(IT-35). ISOtunes® devices with SafeMax™ Technology are OSHA, and
ANSI compliant and, when designated, meet the European Safety Standard
EN352.
Aware Technology™
This product includes Aware Technology. This is a microphone technology
that allows the user to hear the world around them, but always at a safe
listening level. When ambient noise breaches a safe listening level, the mi-
crophone technology immediately responds and attenuates to a safe level.
This feature automatically turns on when the product turns on. Adjusting
the Aware volume is easy. Simply press the Aware Volume Up and Down
Button.
Cleaning and Maintenance
• Clean your ISOtunes LINK Aware by gently wiping them with a
clean, damp cloth with mild soap.
• Do not immerse the hearing protector in water.
• Do not use abrasive cleaning solvents to clean
the hearing protector.
If the hearing protector gets wet from sweat or rain, please discontinue use
and turn the earmuff outwards and allow to dry.
The ear cushions and foam liners should be regularly inspected for deterio-
ration, cracking, or other damage.
