Changing batteries
Base station
If the flat battery symbol appears in the display (see page 9) all batteries must be changed for
ones of the same type as described in Section 2 (Battery operation, page 5).
Always change all the batteries and use only high-quality alkaline cells.
Please note!
After changing the batteries, the weather station will be re-initialized, all stored settings
will be lost and will have to be re-entered.
Wireless sensors WS 2510-22, WS 2510-27
The batteries in these sensors have a life of up to three years (alkaline batteries).
They must be changed when the display of the appropriate sensor in the base device display
does not appear for more than 24 hours and there is no general and longer lasting interference of

the radio path, which can usually be recognized by the fact that data transmission from other,
neighboring sensors has also broken down (see section 5,"Interference").
The battery is changed by opening the battery compartment on the rear of the sensor housing,
removing the discharged battery and inserting two new AA alkaline batteries in the correct
polarity according to the markings in the battery compartment. Replace the battery compartment
cover and the sensor is ready for use. After a few seconds the data from this sensor will appear
on the display.
Other components of the system do not require a battery change as they are powered by
solar cells. Integrated batteries provide power during the hours of darkness and periods of
bad weather.

Information on fault removal
Possible faults that could impair the correct display of the transmitted readings are:
No reception – The distance between transmitter and receiver is too great.
Reduce the distance between the transmitter and the receiver.
No reception – dense shielding materials are positioned between the transmitter and the
receiver (thick walls, reinforced concrete, ...)
Find another position for the transmitter and receiver. See also section 6 ("Range").
Transmitter batteries are discharged.
Change batteries.
Transmitter is blotted out by a source of interference (radio device, radio head
set/loudspeaker)
Remove source of interference or find alternative location for transmitter and receiver.
A newly linked wireless sensor (e.g. after change of battery) is automatically accepted by
the system and the associated data is displayed.
Often the interference is of a temporary nature (radio telephony) or can be removed very easily. If
there are radio headsets, wireless baby phones or similar devices operating on 433MHz in your
house or in the neighborhood their turn-on time is normally limited. Most of these devices permit
change to a disturbance-free frequency.
A measure such as this effectively cuts out interference.
A wireless sensor interferes with other devices in the 433MHz range
The transmissions from a wireless sensor can interfere with other devices on the same channel
for a short period (every 3 minutes for about 200 ms).
Further information on installation and removal of interference
Under critical reception conditions the sensor test mode makes it easier to choose the best
possible location. For this purpose, the sensor concerned is put in test mode, so that every four
seconds data is transmitted.
To activate the test mode remove the batteries from the indoor sensors and the magnets from the
outdoor sensors and refit them after a delay of at least 60 seconds.
Rotate the weather station a little if required, and if reception is bad, locate it away from electric
motors, electrical machines, televisions, computer monitors and large metal surfaces.
