Warning! If the recommendations given in this manual are not adhered to, the protection afforded by the headset will be

severely impaired.

IMPORTANT! For the best protection, brush aside hair around the ears so the ear cushions fit snugly against the head.

Spectacle frames should be as thin as possible and fit close to the head to minimise acoustic leakage.

6. TECHNICAL DATA

The attenuation values and noise levels for the headset are tested and approved according to EN 352-1:2002, EN 352-3: 2002,

EN 352-4: 2001, EN 352-6 : 2002. Testing performed and Certificate issued by Combitech AB, Box 168, SE-73223 Arboga,

Sweden, ID#2279.

Explanation of the attenuation data tables:

1. Weight

2. Frequency (Hz)

3. Mean attenuation (dB)

4. Standard deviation (dB)

5. Assumed Protective Value (dB)

6:2 Sound exposure when using the Flex jacket (G)

The earphone level for music is measured at:

Max AUX input signal level = 1,5 V rms

Table (G) gives the Sound pressure values corresponding to the input signal level applied on the Flex jacket (B:6).

G:2 gives the Mean sound pressure value (dBA), and G:3 gives the Sound Pressure Standard Deviation (dBA) at a specified

input signal Voltage level (G:1) (mV, RMS).

AUX input signal level: 32 mV rms = 82dB

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.

On WS ProTac XP the criterion levels that are defined in EN352-4 is: L = 99dBa M = 106dBa H = 117dBa

6:4 Battery type

Many types of AA 1.2–1.5V batteries can be used (NiMH, NiCd, Alkaline), but only NiMH and NiCd batteries can be recharged.

6:5 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 Battery Life time

Surround + Bluetooth (active) > 24h

Surround only + Bluetooth Off > 150h

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 tested in

accordance with: EN 300 328-17 (radio test), EN 301 489-1/-17 (EMC test), EN 60 950-1 (electric safety), FCC part 15.247

(US radio test) and I.C. (Canadian radio test).
