4. Set up Instruction On/Off Power on Insert batteries. (users may need a screwdriver to open) Turn on Press and hold the function key for 3 seconds till the green indicator flashes once. Turn off (Restore to factory setting) Press and hold the function key for 5 seconds till green indicator flashes for 20 times. Power off Remove Batteries. 1. Remove and insert the battery; the device is at off state by default.
5. Data Report The device will immediately send a version packet report along with an uplink packet including temperature1, temperature2 and battery voltage. The device sends data in the default configuration before any configuration is done. Default setting: MaxTime : Max Interval = 15 min = 900s MinTime : Min Interval = 15 min = 900s BatteryChange: 0x01 (0.1V) TemperatureChange:0x0064 (10°C) Note: The device report interval will be programmed based on the default firmware which may vary.

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.
