consecutive failed attempts during normal operation). Please check the following
points:
1. The distance of the Weather Station or transmitter should be at least 1.5 to 2
metres away from any interfering sources such as computer monitors or TV
sets.
2. Avoid positioning the Weather Station onto or in the immediate proximity of
metal doors or window frames.
3. Using other electrical products such as headphones or speakers operating on
the same signal frequency (868 MHz) may prevent correct signal transmission
and reception.
4. Neighbours using electrical devices operating on the 868 MHz signal frequency
can also cause interference.
5. "Visibility" of weather station and transmitter (e.g. through a window) increases
the range.
Note:
When the 868 MHz signal is received, do not re-open the battery compartment cover
of either the transmitter or Weather Station, as the batteries may spring free from the
contacts and force a false reset. Should this happen accidentally then reset all units
(see Setting up above) otherwise transmission problems may occur.
During normal operation, after the outdoor display shows "- - -", the weather station
will change to receive the outdoor data every 15 minutes, until the data is read. Then
the reception period will return to 4.5 seconds.
If no reception is possible despite the observation of these factors, all system units
have to be reset (see Setting up).
