eartips (S,M,L), and 3 sets of double ange silicone eartips (S,M,L).

Choose the size that ts best in your ear canal. Remember, the

snugger the t, the better the noise reduction. The silicone eartips

are not tested for noise attenuation and should not be used in

noisy environments�

Fitting

1� Carefully roll the foam eartip on the stem/sound port (Fig. 1)�

2� Insert the eartip into your ear as deeply as comfortable (Fig. 2).

levels above 5 volts.

Noise Attenuation

This product has been tested to the European Safety Standard

EN 352-2:2020 and the ANSI S3�19-1974 standard for a hearing

protector, with a Single Number Rating (SNR) of 31 dB and a Noise

Reduction Rating (NRR) of 25 dB� Full testing details are available in

the Noise Attenuation section of this booklet�

ANSI S3.19-1974

American National Standards Institute

The level of noise entering a person’s ear, when ISOtunes® FREE

2�0 earbuds are worn as directed, is closely approximated by the

dierence between the A-weighted environmental noise level and

the Noise Reduction Rating (NRR). Improper t of this device will

reduce its eectiveness in attenuating noise. Consult the enclosed

instructions for proper tting. ISOtunes FREE 2.0 should not be

used if a proper t is not achieved or maintained.

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® FREE 2�0 is 25 dB�

3� The noise level entering the ear is approximately equal to 75 dB�

EN | 14

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 gunre.

EN 352

European Comm. for Standardization (CEN)

The product has been tested and approved in accordance with

personal protective equipment (PPE) standards: EN 352-2:2020,

EN 352-9:2020, and EN 352-10:2020�

The earplugs are provided with level-dependent attenuation and

safety-related audio input Check correct operation before use� If

distortion or failure is detected, refer to the troubleshooting advice�

B4: Frequency (Hz)

B5: Mean Attenuation (dB)

B6: Standard Deviation (dB)

B7: Assumed Protection Value (APV) (dB

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)

Please note that the SNR is based on the continuous wear

of the product�

The output of the audio circuit of the hearing protector may

exceed the exposure limit level

Please note, ISOtunes FREE 2�0 provides an entertainment

audio facility�

The audibility of warning signals at a specic workplace may be

impaired while using the entertainment facility�

Opladning af ørepropper

Der er tre batterier, som skal oplades:

• Opladning af opladningsetuiets batteri

• Batteri i venstre øreprop

• Batteri i højre øreprop

Læg ørepropperne i opladningsetuiet. Øreproppernes LED-indikatorlampe (A) skal

lyse konstant rødt, hvilket indikerer, at ørepropperne oplades. Hvis LED-indikatoren

ikke vises, henvises til fejlndingsafsnittet sidst i denne brugervejledning.
