Transmission Range
The transmission distance from the thermo-hygro sensor to the base
station in open space under optimum conditions is 25 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 dis-
tance.
-
Broadband interferences in municipal areas can reach levels
reducing 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
21. 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 techni-
cian. Opening or improper handling of the units will invalidate
any guarantee.
