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 d�(A).
The TT4 protection level is compliant with pertinent Australian legislation.
Important: In some jurisdictions, applicable regulations or laws may mandate the required setting
you use. The Default level provides a protection level of 118 d�(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.
