  • Page 3: Introduction

    R718EB is the Class A device based on the LoRaWAN protocol of Netvox. The device detects the tilt angle of three axes. When the device moves or shakes beyond the set threshold, and the angle variation of any one of the three axes is greater than the set threshold, it will immediately report the current tilt angle of the X, Y, and Z axes and the battery voltage.

  • Page 11: Information About Battery Passivation

    8. Information about Battery Passivation Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high.

  • Page 12: Important Maintenance Instruction

    9. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: • Keep the device dry.
