5. TECHNICAL DATA

5:1 Attenuation values, SNR
Headband (D:1)
Helmet attachment (D:2)
The attenuation values and noise levels for the headset are tested and
approved according to EN 352-4: 2001, 2002, EN 352-8: 2002, EN 352-1: 2002 and EN 352-3: 2002. Certificate issued by
CombiTech AB, SE-73281 Arboga, Sweden
Explanation of the attenuation data tables:
1. Weight
2. Frequency (Hz)
3. Average attenuation (dB)
4. Standard deviation (dB)
5. Expected attenuation (dB)
These ear muffs should be fitted to, and used only with, the industrial safety helmets listed in table H:
Explanation of table H:)
1. Helmet manufacturer
2. Helmet model
3. Test report
4. Attachment
5. Size ranges: S= Small, N= Medium, L= Large
5:2 Sound exposure when using the 3.5 mm audio input
The earphone level for music is measured at no more than 82 dB(A) equivalent sound level.
5:3 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 dominated by any
given frequency, and L is low-frequency dominated noise.
5:4 Battery type
All types of AA 1.2–1.5V batteries can be used (NiMH, NiCd, Alkaline, Lithium, Manganese, etc), but only NiMH and NiCd batteries
can be recharged.
5:5 Battery life
The expected battery life may vary depending on the brand of batteries and the temperature in which the product is used. Low battery
level is indicated by a voice saying: "low battery". The headset functions will not work optimally if the battery is low.
2*AA Alkaline
Surround +FM radio+ Bluetooth (standby) > 32 h
Surround + FM radio+ Bluetooth (active) > 23 h
5:6 Bluetooth
Version 2.1
A2DP 1.2
HSP 1.2
HFP 1.5
AVRCP 1.0
The headset is designed for Bluetooth standard V.2.1 (headset and handsfree profiles + A2DP) and is certified according to:
EN 300 328 (radio test), EN 301 489-1/-17 (EMC test), EN 60 950 (electric safety, low voltage directive).
