2.5.5 Protection level selection

Your headset offers a choice of 4 protection levels (plus its additional basic protection level). These levels protect you against sudden, overly-loud sound spikes that may come from the phone network (such as shrill telefax signals or network interference), and provide a limit to the maximum noise exposure from the headset during your workday.

The number of hours (on average) you spend on the telephone per day determines the set- ting you should select. All 4 protection levels meet and exceed de facto global protection levels, and are compliant with NIOSH standards, and EU health and safety codes of 85 dB(A). The TT4 protection level is compliant with pertinent Australian recommendation.

Important: In some jurisdictions, applicable regulations or laws may mandate the required setting you use. The Default level provides a protection level of 118 dB(A). Your headset protects you

against overly-loud sound spikes. If you use the telephone’s handset for calling, you will not have this protection.
