1. Introduction
R718WBA is a detection device that is a ClassAtype device based on LoRaWAN open protocol of Netvox. The device is applied to
detecting water leakage and surrounding ambient temperature and humidity. R718WBA is compatible with LoRaWAN protocol.
LoRa Wireless Technology:
LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Compared with
other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It can be
widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic meter reading,
building automation equipment, wireless security systems, industrial monitoring. It has features like small size, low power consumption,
long transmission distance, strong 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.

Note:
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 collected data is compared with the last reported data. If the variation of the data is greater than the ReportableChange value,
the device will report according to MinTime interval. If the data variation is not greater than the last reported data, the device
will report according to MaxTime interval.
3) We do not recommend setting the MinTime Interval value too low. If the MinTime Interval is too low, the device will wake up
frequently and the battery will be drained soon.
4) When the device sends a report, regardless of the resulting from data variation, button pushed or MaxTime interval, another
cycle of MinTime/MaxTime calculation will start.
6. Installation
This product comes with waterproof function. When using it, the back of it can be adsorbed on the iron surface, or the two ends can be
fixed to the wall with screws.
R718WBA has built-in magnet (as the figure on the left below). When installed, the device can attach to the surface of the ferrous object
easily. In order to installing the device firmly, users can secure it to the wall or other surface by using screws (need to purchase by
oneself) (as the figure on the right below).
Note:
Do not install the device in a metal shielded box or other electrical equipment around it to avoid affecting the wireless
transmission of the device.

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.
*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

8. Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• 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 applies to your device, battery, and accessories. If any device is not working properly, please take it to the nearest
authorized service facility for repairing.
