2.4.5 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.
CAUTION: Loud and high-pitched noise may cause temporary or permanent damage to your hearing.
This equipment is designed to offer protection against loud and high-pitched noises and conforms to

tion. To reduce the potential damage to your hearing that may be caused by loud and high pitched
