• Always replace the whole set of batteries.
• Do not mix full with „half-full” batteries“.
• Always use four batteries of the same type and manufacturer.
• Do not mix batteries with accumulators.
• As already mentioned, accumulator operation is possible, the durability is, however, appreciably
lower than with batteries.
• For changing the batteries, proceed as described in section 7. c).
Please observe the following:
After replacing the batteries, all data, values stored in the base station (e.g. time,
date etc.) are deleted and have to be entered again.
b) Combination sensor, outdoor sensor
When the display of the sensor concerned fails for more than 4 hours, the batteries are to be
replaced with new ones as described in section 7. a) and b).
Check as whether there is possibly some disturbance in the radio transmission which
is the cause for the failure of the data transmission. In this case also, there will be no
indication in the display of the base station.
The cause could be, for example, a metal object in the radio path (e.g., a parked
vehicle).
