Environmental compatibility
No contact with substances harmful to human health can occur if the system is used
properly. The synthetic materials used in this device consist of partially recycled gra-
nulate. Our packaging does not contain any synthetic materials. Only cardboard and
paper from partially recycled material is used.
Functioning in the event of power failure
If you want to guarantee that your telephone system is also available in the event of a
power failure, an uninterruptible power supply (UPS) is available as an optional ac-
cessory. This ensures that the system will continue to function for several hours in the
event of a power failure.
