HP BT400 User Manual page 23

This product is designed to be connected to the analog
Switched Telecommunication Networks (PSTN) of the
European Economic Area (EEA) countries/regions.
Network compatibility depends on customer selected
settings, which must be reset to use the equipment on a
telephone network in a country/region other than where the
product was purchased. Contact the vendor or Hewlett-
Packard Company if additional product support is
necessary.
This equipment has been certified by the manufacturer in
accordance with Directive 1999/5/EC (annex II) for Pan-
European 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 network termination point.
In the event of problems, you should contact your
equipment supplier in the first instance.
This equipment is designed for DTMF tone dialing and
loop disconnect dialing. In the unlikely event of problems
with loop disconnect dialing, it is recommended to use this
equipment only with the DTMF tone dial setting.
