12. Range
The transmission range of the radio signals between outdoor sensor and weather station is up to 100m under
optimum conditions. This is often also called "free field range".
However, this ideal arrangement (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 due to:
• Walls, reinforced concrete ceilings
• Coated/metallized insulation glazing
• Vehicles
• Trees, bushes, earth, rocks
• Proximity to metal & conducting objects (e.g. radiators)
• Proximity to human body
• Broadband interferences, e.g. in residential areas (DECT telephones, cellular phones, radio-controlled head-
phones, 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 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.
13. Maintenance and Cleaning
Maintenance or repairs are only permitted by a specialized skilled person or a specialized repair shop. There are no
components on the inside of the product that need maintenance by you; this is why you should never open it (apart
from the described approach to insert or change the batteries, in these instructions).
To clean the exterior of the weather station, a dry, soft and clean cloth is sufficient.
Dust on the weather station can be easily removed with the help of a long-haired, soft and clean brush and a vacuum
cleaner.
Don’t press too hard on the display, this may cause scratch marks or lead to failure of the display.
To remove dirt on the outdoor sensor, a soft cloth, slightly dampened with lukewarm water can be used.
Never use aggressive cleansing agents or other chemical solvents since this may damage the surface
of the housing or even impair operation.
