Transmission Range
The transmission distance from the thermo-hygro sensor to the base
station in open space under optimum conditions is 100 meters.
Although the signal transmission may travel though solid surfaces or
objects, the following points should be avoided if possible:
-
High frequency interferences of any kind.
-
Constructions of any kind or trees.
-
The distance of transmitter and receiver to conducting planes or
object (including the human body or the ground) does influence the
transmission characteristics and thus the transmission distance.
-
Broadband interferences in municipal areas can reach levels re-
ducing the signal/noise ratio over the entire frequency band, thus
also reducing the transmission distance.
-
Devices working close by (example a neighbor's house) may also
influence reception.
-
Poorly shielded PCs can cause interferences that will reduce or in
some cases stop reception

Cleaning and Maintenance
-
Clean the housing and screen of the base station only with a soft
damp cloth. Do not use abrasives or solvents.
-
Ensure that the rain sensor does not collect leaves or other dirt by
checking the funnel for blockages every now and then. Also clean
the seesaw of the sensor with a damp cloth and check by lightly
tapping with your finger that it can move freely from side to side.
-
Do not clean the funnel with the bottom half of the rain sensor
attached nor the bottom part itself under running water. This may
bear the danger of water entering the unit's inner parts and cause
damages.
-
Do not immerse the base station in water.
-
Should there be damage to this product, please do not attempt to
make any repairs. Please take this unit to a qualified technician.
Opening or improper handling of the units will invalidate any guar-
antee.
