WARNING!
These ear plugs should not be used where there is a risk that the connecting cord
could be caught up during use.
WARNING!
If these recommendations of use, storage and maintenance described in this user
instruction are not adhered, the protection afforded by the ear plugs will be severely
impaired.
5. Technical Data
5:A
Attenuation values, SNR
The nominal range of diamters of the ear plugs are 8-12 mm
The attenuation values are tested and approved according to PPE directive 89/686/
EEC and applicable sections of standard EN 352-2:2002 and EN 352-7:2002
Certificate issued by FIOH, Topeliuksenkatu 41, FI-00250 Helsinki, Finland, ID#0403.
Explanation of the attenuation data tables:
1. Weight
2. Frequency (Hz)
3. Average attenuation (dB)
4. Standard deviation (dB)
5. Expected attenuation (dB)
5:B Input signal level/usage time for audio input
Electrical audio input of the earplugs was measured in accordance with in-house-
method derived from those described in standard EN 352-6:2002
Maximum permitted audio signal in relation to usage time.
To prevent harmful effects on hearing, the input signal should not exceed the
specified values (average speech sound level). The long-term average value of the
earphone volume is measured at a level corresponding to no more than 82 dB(A)
sound level. Electrical input level for which the mean plus one standard deviation
A-weighted diffuse-field related sound pressure level is equal to 82 dB is at RMS-
voltage U = 29 mV.
5:C Criterion levels (G)
A criterion level is the amount of noise (measured as A-weighted sound pressure)
outside the hearing protector that gives 85 dB(A) inside. The noise level depends on
the type of noise. H is high-frequency dominated noise, M is noise that is not domi-
nated by any given frequency, and L is low-frequency dominated noise.
5:D Battery type
2 X AAA 1.2–1.5V
5:E Battery life :
~ 400h (5% talk, 5% listen, 90% On time)
The expected battery life may vary depending on the brand of batteries and the tem-
perature in which the product is used. A Low-Battery condition will generate 3 beeps
that repeats every 10 seconds until the batteries are replaced.
5:F Storage & Operating Temperature
Operating Temp:
-32°C to +55°C
Storage Temp:
-32C° to +63°C
Storage humidity:
‹ 85%
Shelf life
‹ 5 years
5:G
