Press the function key to immediately detect the current voltage and state of water leakage, and a currently detected data packet will be reported. LoRa Wireless Technology: LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance. Widely used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation equipment, wireless security systems, industrial monitoring. Main features include small size, low power consumption, transmission distance, anti-interference ability and so on. LoRaWAN: LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different manufacturers. 2 2.

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. If the data variation is not greater than the last data reported, the device reports according to MaxTime interval. 3) We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up frequently and the battery will be drained soon. 4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another cycle of MinTime/MaxTime calculation is started. 10 6. Installation The device is waterproof. The installation instruction is as the figure below. 1.The device can be fixed on the cover by the force rubber, or make the hole in the cover and bundle the device with cable ties. 2. The length of the probe can be trimmed according to personal requirements. 3. When the level of the hand wash is lower than electrode rods, the device will issue a warning.

If users need to detect water leakage on the ground, please refer to the following figure. R720FW 11 Note: Please use the screwdriver to open the cover to install the battery. 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. *To determine whether a battery requires activation Connect a new ER14505 battery to a 68ohm resistor in parallel, and check the voltage of the circuit. If the voltage is below 3.3V, it means the battery requires activation. *How to activate the battery 1) Connect a battery to a 68ohm resistor in parallel 2) Keep the connection for 6~8 minutes 3) The voltage of the circuit should be 3.3V 12 8. Important Maintenance Instruction The device is a product with superior design and craftsmanship and should be used with care. The following suggestions will help you use the warranty service effectively. · Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic circuits. In case the device is wet, please dry it completely. · Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components. · Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts. · Do not store in excessive cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside which will destroy the board. · Do not throw, knock, or shake the device. Treating equipment roughly can destroy internal circuit boards and delicate structures. · Do not wash with strong chemicals, detergents, or strong detergents. · Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation. · Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode. All the above suggestions apply equally to your device, batteries, and accessories. If any device is not operating properly. Please take it to the nearest authorized service facility for repairing. 13微软用户 Adobe PDF Library 11.0
