Replacing The Battery; Base Station; B) Multipurpose Sensor, Outdoor Sensors - Conrad WS222 Bedienungsanleitung

10. Replacing the Battery

The replacement interval varies significantly for batteries and accumulators. High-quality
alkaline batteries are the most efficient ones, whereas accumulators or cheap zinc-
carbon batteries require a more frequent replacement.
a) Base Station
If the battery empty symbol (
• Always replace the whole set of batteries.
• Never mix full and semi-full batteries.
• Always use four batteries of the same type and manufacturer.
• Never use batteries and accumulators together.
• As already mentioned before, the station can be operated by accumulators, but if batteries are
used, the operating time will be much longer.
• Proceed as described in chapter 7 c) to replace the batteries.
Please note:
After replacing the batteries, all data/values saved in the base station (e.g. time, data etc.)
are deleted and have to be entered anew.

b) Multipurpose Sensor, Outdoor Sensors

If the indication of the individual sensor is not displayed over a period of more than 24 hours, the
batteries are to be replaced as described in chapters 7a) and b).
Check, if the failed data transfer is caused by an interfered radio transmission. In this
case an indication will not be given in the display of the base station neither.
Another possible source of the problem could be for example a metal part placed in the
radio line. Such a problem can be detected by the fact that the data transmission of other
sensors being closer positioned also fail. (See chapter 11 on next page.)
