Range - Conrad KW 9110 Bedienungsanleitung

14. Range

The transmission range of the radio signals between outdoor sensor and weather station is up
to 30m under optimum conditions. This is also often termed "free-field coverage".

However, this ideal situation (e.g. weather station and outdoor sensor on a plain,
even meadow without trees, houses etc.) never exists in practice.
Normally the weather station is installed in the house and the outdoor sensor is mounted, e.g.
outdoor next to the window.
The range can sometimes be considerably reduced by:
• Walls, reinforced concrete ceilings
• Coated/metallised insulated glass
• Vehicles
• Trees, brushes, earth, rocks
• Proximity to metallic & conductive objects (e.g. heating elements)
• Proximity to human body
• Broadband interferences, e.g. in residential areas (DECT telephones, mobiles, radio-
controlled headphones, radio-controlled speakers, other radio-controlled weather stations,
babyphones etc.)
• The proximity to electric motors, transformers, power supply units, computers
• Proximity to badly shielded or openly operated computers or other electric devices

As local conditions vary from site to site, a definite range cannot be guaranteed.
However, trouble-free operation is usually possible in a detached house. If the
weather station doesn't receive any data from the outdoor sensor (despite new
batteries), reduce the distance between outdoor sensor and weather station,
change the installation site.
