Transmission Range
The transmission distance from the thermo-hygro sensor to the base station in
open space under optimum conditions is 100ft. Although the signal transmis-
sion may travel though solid surfaces or objects, the following points should be
avoided if possible:
•
High frequency interferences of any kind.
•
High densities of trees.
•
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 influ-
ence reception.
•
Poorly shielded PCs can cause interferences that will reduce or in some
cases stop reception
•
The sensor and receiver should not be mounted on metal surfaces as this
will reduce transmission range.

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 check-
ing 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 fin-
ger 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 guarantee.
