TROUBLESHOOTING
Signal disconnection
If without obvious reasons the display of the outdoor temperature goes
blank, please check the following:
1. The remote unit is still in place.
2. The batteries of both the remote unit and main unit are not empty.
Replace batteries with new ones if necessary.
Note: When the temperature falls below freezing point, the batteries of
outdoor units will freeze, lowering their voltage supply, effective range,
and life span.
3. All units required are within range and the path is clear of obstacles
and interference. Shorten the distance if necessary.
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.
