Range - Conrad Electronic LumiNight Bedienungsanleitung

16. Range

The transmission range of the radio signals between outdoor sensor and base station is up to
75m under optimum conditions. This is often also called "free field range".

However, this ideal arrangement (eg base station and outdoor sensor on a plain,
even meadow without trees, houses etc.) never exists in practice.
Normally the base station is set up in the house and the outdoor sensor, eg outside next to the
window.
The range can sometimes be considerably reduced due to:
• Walls, reinforced concrete ceilings
• Coated/metallized insulation glazing
• Vehicles
• Trees, bushes, earth, rocks
• Proximity to metal & conducting objects (eg radiators)
• Proximity to human body
• Broadband interferences, eg in residential areas (DECT telephones, mobiles, radio-
controlled headphones, radio-controlled speakers, other radio-controlled weather stations,
babyphones etc.)
• Proximity to electric motors, transformers, power-supply units, computers
• Proximity to badly shielded or openly operated computers or other electric devices

Since local conditions are different at every location site, a definite range cannot
be guaranteed.
However, normally in a detached house trouble-free operation is possible. When
the base station doesn't receive any data from the outdoor sensor (despite new
batteries), reduce the distance between the outdoor sensor and base station,
change the installation site.
