12. Range

The transmission range of the radio signals to the base station is 100 m under optimum conditions. This is
often described as the "free field range".
This ideal arrangement (e.g. base station and outdoor sensor on a smooth, level field without trees,
houses etc.) is, however, never found in practice.
Normally, the base station is set up in the house, the combination in the garden and further outdoor sensors,
for example in ancillary buildings (e.g. in an aviary) or garage.
The range can be reduced considerably partly through:
• walls, reinforced steel ceilings
• coated/vapoured insulation glass panes
• vehicles
• trees, bushes, earth, rocks
• closeness to metal & conductive objects (e.g. radiators)
• closeness to the human body
• broadband disturbances, e.g. in residential area (DECT telephones, mobile telephones, radio head-
phones, radio loudspeakers, other radio weather stations, baby phones etc.)
• closeness to electric motors. Transformers, network parts pr computers
• closeness to poorly shielded or openly operated computers or other electrical devices
As the local circumstances are different at every place of set-up, a certain range cannot be guaran-
teed.
If the base station is receiving no data from the combination sensor or any additionally existing out-
door sensors (in spite of new batteries), reduce the distance between the outdoor sensors and the
base station, change the place of set-up .
Observe section 7 and 11 of these operating instructions.
