10. Range
The transmission range of the radio signals between handset and indoor unit is up to 100 m under optimum conditions.

between transmitter and receiver without any interferences).
In practical operation, however, there are walls, ceilings etc. between the transmitter and the receiver which reduce
the range correspondingly.

however, operation in a family home is possible without any problems.
The range may be considerably reduced by:
• Walls, reinforced concrete ceilings, plasterboard walls with metal stand construction
• Laminated/coated insulating glass panes
• Proximity to metal & conductive objects (e.g. heater)
• Proximity to the human body
• Other devices on the same frequency (e.g. DECT phones)
• Proximity to electrical motors/devices, transformers, mains adapters, computers
