Page 3: Introduction
1. Introduction R718A01, mainly used to detect the temperature and humidity at low temperature environment such as the freezer air. It collects data over LoRa network and sends it to devices to be shown, fully compatible with LoRa protocol. LoRa Wireless Technology: LoRa is a wireless communication technology dedicated to long distance and low power consumption. -

2. When the temperature and humidity detected by R718A01 is compared with the last reported values, it will report current values when the temperature change exceed 1°C (default) or the humidity change exceed 1%(default). - Page 12 Battery installation steps Please replace the battery by professionals! The device must use 2 sections of ER14505 battery (3.6v/section) Please note that the positive and negative poles of the battery should not be installed reversely. Step 1 Unscrew the four corners of the device with a screwdriver, as shown in the red circle below. Step 2 Put the batteries into the battery bay of the device and note the positive and negative poles of the battery, please do not insert the battery reversely.

Page 13: Information About Battery Passivation
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 14: Important Maintenance Instruction
8. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: • Keep the device dry. Rain, moisture, or any liquid might contain minerals and thus corrode electronic circuits. If the device gets wet, please dry it completely.
