Notes on rectifying malfunctions

Possible malfunctions that could prevent transmitted measured values being
displayed properly:
No reception – The distance between the transmitter and the receiver is too long or too short
(<1 m).
Decrease/increase the distance between the transmitter and the receiver.
No reception – Materials with good shielding properties are located between the transmitter
and the receiver (thick walls, reinforced concrete, etc.).
Find another position for the transmitter or the receiver. Refer also to Section 6
("Range").
No reception – Transmitter batteries are empty.
Replace the batteries.
No reception – The transmitter is subject to a source of interference.
(Wireless device, radio headphones/loudspeaker)
Eliminate the source of interference or find another position for the transmitter or the recei-
ver. Often the interference is only present on a temporary basis (radio telephony) or can be
eliminated very easily. If radio headphones, wireless baby monitors or other similar devices
are operated at 868 MHz in your home or in the neighbourhood, for example, they are usually
only switched on for a limited period of time. The majority of these devices can be moved
to an interference-free frequency and a measure such as this can mask interference really
effectively.
Wireless sensor interferes with other devices in the 868 MHz band
Transmissions from the wireless outdoor sensor can interfere temporarily (every 2 to 3 min for
around 100 ms) with other devices working on the same channel.
Additional notes on start-up and the rectification of malfunctions
Rotate the weather station a little if necessary or, if reception is poor, position it far
away from electric motors, electrical machinery, television sets, computer monitors
and large metal surfaces.
To make start-up easier you can initially position the sensors in the vicinity of the base unit
(but at least 1 m away from it). This enables you to check that the sensor is transmitting data
correctly.
