
When the 868MHz signal is received correctly, do not re-open the battery
cover of either the transmitter or Temperature station, as the batteries may
spring free from the contacts and force a false reset. Should this happen
accidentally then reset all units (see Setting up above) otherwise
transmission problems may occur.

The transmission range is about 100 m from the transmitter to the
Temperature station (in open space). However, this depends on the
surrounding environment and interference levels. If no reception is possible
despite the observation of these factors, all system units have to be reset (see
Setting up).
