h) 868 MHz reception test
The weather station should receive and display the outside area data within 5 minutes after
being put into operation. If they aren‘t displayed within 5 minutes after the basic setting or if the
signal reception in normal display mode is continuously jammed so that the outside area display
only shows “- - -” then please check the following:
1. The distance of weather station and outside transmitters to sources of interference such as
computer monitors or television sets should be at least 1.5 - 2 meters.
2. Avoid placing the units directly against or in the vicinity of metal doors or window frames.
3. The use of other devices working on the same frequency (868 MHz) such as headphones
or loudspeakers can prevent correct signal transmission.
4. Reception interference can also be caused by neighbours who operate devices working on
the same frequency (868 MHz).
If the 868 MHz signal is correctly transmitted and received, then the battery cases
of the weather station and outside transmitters should no longer be opened. The
batteries could thereby become disengaged from the contacts and thus bring about
an unwanted reset. If this should nonetheless occur, then all units have to be set anew
to avoid transmission problems (see “Basic setting” above).
The transmission range of the outside transmitter to the weather station in a free field
is about 100 meters. However, this depends on environmental conditions and possible
sources of interference. If reception is not possible despite consideration of all the
factors mentioned above, then all units have to be reset (see “Basic setting” above).
10. Mounting
Before permanently mounting the brackets, please place all units in the desired
installation or mounting locations and check whether the outside area data are
correctly received. If this is not the case, then in most cases a slight shift of mounting
locations is sufficient for adequate signal reception.
a) Placement of the base station
The weather station can be installed in free-standing fashion or mounted on a wall. Before
mounting on a wall, make sure that the outside temperature values can be correctly received at
the desired mounting location.
