Page 16 Notes : 1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data. 2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value, the device reports according to MinTime interval.

Page 20 7. 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 21 8. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: •Do not put the device near or submerge into water. Minerals in rain, moisture, and other liquids could cause corrosion of electronic components.
