4. Error analysis:
Did you exactly follow the operating instructions? First insert the batteries in the
transmitter and THEN in the receiver! Check the basis device and the outdoor sensor
2-3 days in a joint room before sending it back, ensure that there are no interference
sources to check the general function. Also check whether the batteries in your pro-
duct are still charged!
Then try to find out the cause of the problem, e.g. by contacting our hotline.
Change the location of the transmitter or the receiver to determine the best trans-
mission/receiver connection!
