TROUBLESHOOTING
Signal disconnection
If the display of the outdoor temperature goes blank without obvious
reasons, please check the following:
1. The outdoor sensor is still in place.
2. The batteries of both the sensor and the main unit are not empty.
Replace batteries with new ones if necessary.
NOTE!
When the temperature drops below freezing point, the batteries of the
outdoor sensor can also freeze and their voltage and lifetime are reduced.
3. Both devices are positioned within the reception area and the
reception area is free of sources of interference and obstacles. If
necessary, reduce the distance between the devices.
Transmission collision
Signals from other household devices, such as door bells, home security
systems and entry controls, may interfere with those of this product and
cause temporarily reception failure. This is normal and does not affect
the general performance of the product. The transmission and reception
of temperature readings will resume once the interference recedes.
