TBR 21
This equipment has been approved [Council Decision 98/482/EC - "TBR 21"] for
single terminal connection to the Public Switched Telephone Network (PSTN).
However, due to differences between the individual PSTNs provided in different
countries, the approval does not, of itself, give an unconditional assurance of
successful operation on every PSTN termination point. In the event of problems,
you should contact your equipment supplier in the first instance. For more
information about applicable countries, please refer to "Regulations and safety
notices" on page 37
Notice for Australia
For safety reasons, only connect headsets with a telecommunications
compliance label. This includes customer equipment previously labelled
permitted or certified.
