Note:
Please do not disassemble the device unless it is required to replace the batteries.
Do not touch the waterproof gasket, LED indicator light, function keys when replacing the batteries. Please use suitable
screwdriver to tighten the screws (if using an electric screwdriver, it is recommended to set the torque as 4kgf) to ensure the
device is impermeable.
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.
This lithium chloride layer prevents rapid self-discharge caused by continuous reaction between lithium and thionyl chloride,
but battery passivation may also lead to voltage delay when the batteries are put into operation, and our devices may not work
correctly in this situation. As a result, please make sure to source batteries from reliable vendors, and the batteries should be
produced within the last three months.
If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.
