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 transmission 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 influence reception.
-
Poorly shielded PCs can cause interferences that will reduce or
in some cases stop reception
-
The transmitter and receiver should not be mounted on metal
surfaces as this will reduce transmission range.
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.
