Remedy
• The distance between the base station and outdoor sensors is
too great.
Alter the position of the outdoor sensors.
• Objects or shielding materials are obstructing the radio reception.
Alter the position of the outdoor sensors and the base station.
• The batteries of the outdoor sensors are too weak or flat.
Insert new batteries into the sensors as an attempt.
• Another transmitter on the same or neighbouring frequencies is
disturbing the radio signal of the outdoor sensors. This can be, for
example, radio headphones, radio loudspeakers or similar devices.
Such products are not usually operated constantly; the radio
reception can, for example, be perfect the next day; this makes
the search for the cause more difficult.
If possible, set another frequency on the instruments which can
eliminate the reception problems of the weather station.
• The outdoor sensors transmit their data to the base station approx.
every 3 minutes for a period of 0.1 (100ms) seconds. In this short
period, disturbances in other devices are also possible.
For example, a very short disturbance signal can be audible from
a radio head phone every 3 minutes.
• When inserting the batteries into the outdoor sensors and the base
station (observe this order exactly!), these devices are in
synchronisation mode. A data telegram is transmitted here every
4 seconds which accelerates the recognition and registration of
the outdoor sensors at the base station.
To enforce new synchronisation, remove the batteries from the
base station and outdoor sensors. After that, wait at least 60
seconds before you insert the batteries into the outdoor sensors
again and, lastly, into the base station (observe this order without
fail – first of all insert the batteries into all existing outdoor sensors,
only then into the base station.
In doing so, however, all values/data which the base station has
stored (e.g. minimum values, maximum values and date/time etc.),
are lost.
• Before you position the outdoor sensors, for example in your
garden, carry out a function test as described at the beginning of
section 7.
