六、Attention
1) When the battery appears low voltage warning, it will cause flashing alarm, touch the button does not work, data
received signal, please replace the battery in time.
(Indoor machine: battery voltage is lower than 3.2V or so.
Outdoor machine: battery voltage is lower than 2.4V or so)
2) No outdoor transmitter data can be received: Outdoor confirm product range, 433 MHZ wireless transmission
to 100 meters can be measured without interference without sunscreen, check the battery, whether on the indoor
and outdoor battery symbol flashing said electricity shortage, check whether outdoor fire board 40 seconds lamp
