1. Introduction
R718UBB all-in-one series is a ClassAtype testing device based on LoRaWAN open protocol of Netvox, which can support multiple
combinations of temperature and humidity, CO2, vibration, atmospheric pressure and illumination sensors, and is compatible with
LoRaWAN protocol.
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 device,
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.

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 20 times.
Power off Remove Batteries.
Note:
1. Remove and insert the battery; the device is at off state by default. Turn on the device to use
again.
2. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor
inductance and other energy storage components.
3. In the first 5 seconds after power on, the device will be in engineering test mode.
Network Joining
Never joined the network
Turn on the device to search the network to join.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Had joined the network
(not at factory setting)
Turn on the device to search the previous network to join.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Fail to Join The Network Suggest to check the device verification information on the gateway or consult your platform
server provider.
Function Key
Press and hold for 5 seconds
Restore to factory setting / Turn off
The green indicator rapidly flashes for 20 times: success
The green indicator remains off: fail
Press once The device is in the network: green indicator flashes once and sends a report
The device is not in the network: green indicator remains off
Sleeping Mode
The device is on and in the network
Sleeping period: Max Interval.
When the reportchange exceeds setting value or the state changes: send a data report according
to Max Interval.
Low Voltage Warning

5. Data Report
When the device is powered on, it will immediately send a version package report and then report the device data.
Default setting:
Min interval = 10s (subject to factory setting)
Max interval = 15min (subject to factory setting)
R718UBB,R718UBB1,R718UBB12 reportcount=1
R718UBB123,R718UBB23,R718UBB25,R718UBB125,R718UBB235,R718UBB1235 reportcount=2
Data detection:
When the device is in a network state, the light flashes once after pressing the key, and then reads the data. When the time to
return the corresponding data or configure is up, it will also detect and return the corresponding data information.
(Note: The interval between multiple data packets is mintime)
Note:
1. Before any configuration, the device sends data according to the default configuration.
2. Do not send any configuration before turn on the device.
3. CO2 data will be unstable due to transportation relations, long storage time and other factors.
If the CO2 value which customers test is inconsistent ,or there is large discrepancy of the primary standard,
it can be recalibrated. For specific calibration methods,please refer to command 0x03 CalibrateType.

6. 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 it is suggested that if the storage period is more than
one month from the date of battery production, all the batteries should be activated.
If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.
ER14505 Battery Passivation:
6.1 To determine whether a battery requires activation
Connect a new ER14505 battery to a resistor in parallel, and check the voltage of the circuit.
If the voltage is below 3.3V, it means the battery requires activation.
6.2 How to activate the battery
a. Connect a battery to a resistor in parallel
b. Keep the connection for 5~8 minutes
c. The voltage of the circuit should be ≧3.3, indicating successful activation.

Brand Load Resistance Activation Time Activation Current
NHTONE 165 Ω 5 minutes 20mA
RAMWAY 67 Ω 8 minutes 50mA
EVE 67 Ω 8 minutes 50mA
SAFT 67 Ω 8 minutes 50mA
Note:
If you buy batteries from other than the above four manufacturers, then the battery activation time, activation current, and required
load resistance shall be mainly subject to the announcement of each manufacturer.
7. Precautions for Outdoor Installation
According to Enclosure Protection Class
This standard is equivalent to IEC 60529:2001 Degrees of Protection Provided by Enclosures
The test method of IP65 waterproof grade is:
spray the device in all directions under 12.5L/min water flow for 3min, and the internal electronic function is normal.
The test method of IP67 waterproof grade is:
the device is immersed in 1m deep water for 30min, and the internal electronic function is normal.
IP65, dust-proof and to prevent damage caused by water from nozzles in all directions from invading electrical appliances. It can be
used in general indoor environment and sheltered outdoor environment.
It is not suitable for use in environments with high water pressure,high temperatureand high humidity, such as long time direct sunlight
outdoors and possible direct exposure to rainstorm. If it is really necessary to install in harsh environments, it is recommended to add
sunscreen and rainproof shields when installing.
Case I (face down with LED and buttons) Case II (installed under the rain shield)

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 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 device 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.
