But in practical operation, several ambient conditions reduce
the coverage:
• walls, reinforced concrete ceilings
• coated/vapour-deposited insulating glass panes
• vehicles
• trees, brushes, earth, rocks
• the proximity to metallic objects (e.g. metal door)
• the proximity to the human body
• broad-band interference, e.g. in residence areas (DECT
telephones, mobiles, wireless headphones and
loudspeakers, baby phones, etc.)
• the proximity to electric motors, transformers, power supply
units, computers

computers or other electric appliances
As the local conditions vary at the different places
of installation, a guarantee for a specific coverage
cannot be given.
Generally, the operation of the unit in the radius
