5. Restore to Factory Setting

Operation method: press and hold the button for 5 seconds and the green LED flashes for 20 times,
and R718CK2/T2/R2 will be turned off after successful erasure.

6. Sleeping Mode

R718CT2/CK2/CR2 is designed to enter sleeping mode for power-saving in some situations:
(A) While the device is in the network → the sleeping period is one hour. (During this period,
if the reportchange is larger than setting value, it will wake up and send a data report).
(B) When it is not in the network → R718CT2/CK2/CR2 will enter sleeping mode and wake
up every 15 seconds to search a network to join in the first two minutes. After two minutes, it
will wake up every 15 minutes to request to join the network.
If it's at (B) status, to prevent this unwanted power consumption, we recommend that users
remove the batteries to power off the device.

7. Low Voltage Alarming

The operating voltage threshold is 3.2V. If the voltage is lower than 3.2V, the device will send a
low-power report to the Lora network.
