Introduction
Connection approval
Your ISDN telephone system has a "General Connection Approval". So, anyone is
authorized to put the telephone system into operation. It is not necessary to notify
your network operator.
Environmental compatibility
No contact with substances harmful to human health can occur during due and
proper use of this telephone system. The synthetic materials used in this device con-
sist of partially recycled granulate. Our packing does not contain any synthetic mate-
rials. Only cardboard and paper from partially recycled material is used.
Function in the case of power failure
If you want to guarantee that your telephone system is also available in case of a
power failure, an uninterruptible power supply (UPS) is available as optional acces-
sory. This ensures that the telephone system will continue to function for several
hours during power failure.
