1. Introduction
The R312 is a doorbell button device for Netvox ClassA type devices based on the LoRaWAN open
protocol and is compatible with the 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.

4. Set up Instruction
On/Off
Power on
Insert batteries (users may need a screwdriver to open)
Insert two sections of 3V CR2450 button batteries and close the battery
cover.
Note: Require 2 button batteries to supply power at the same time.
Turn on Press any function key and indicator flashes once meaning it is turned on
successfully.
Turn off
(Restore to factory setting)
Press and hold the function key for 5 seconds and green indicator flashes
20 times.
Power off Remove Batteries.
Note:
1. Remove and insert the battery; the device memorizes previous on/off
state by default.
2. On/off interval is suggested to be about 10 seconds to avoid the
interference of capacitor inductance and other energy storage
components.
3. If press any function key and insert batteries at the same time, it will
enter engineer testing mode.
Network Joining
Never joined the network
Turn on the device to search the network.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Had joined the network
(not restore to the factory setting)
Turn on the device to search the previous network.
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.

Report configuration and sending cycle are as follows:
Min Interval
(Unit:second)
Max Interval
(Unit:second) Reportable Change Current Change≥
Reportable Change
Current Change＜
Reportable Change

MaxTime

Notes:
(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 data collected is compared with the last data reported. If the data change value 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.

6. Installation
(1) This product does not have a waterproof function. After the screening is completed, please place it
indoors.
(2) The dust at the equipment installation position needs to be wiped clean and then pasted.
(3) The battery installation method is as shown below (the battery has a "+" side facing outward)
(Users may need a screwdriver to open the battery cover.)
1. Remove the 3M release paper on the back of the device and attach the device to the smooth wall
(please do not stick it to the rough wall to avoid falling off after a long time use).
Note:
Wipe the wall surface before installation to avoid dust on the wall surface and affect the paste
capability.
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.
2. When the doorbell (R312) button is pressed, the message "Alarm" is sent.
When the device reports data periodically, it restores the "normal" status and sends "normal" status
information.
Note:
With the sound and light alarm (R602A), the audible and visual alarm will ring the door after the
doorbell is pressed.

7. 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.
• Do not use or store the device in dusty or dirty environment. It might damage its detachable parts
and electronic components.
• Do not store the device under excessive heat condition. High temperature can shorten the life of
electronic devices, destroy batteries, and deform or melt some plastic parts.
• Do not store the device in places that are too cold. 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. Rough handling of equipment can destroy internal circuit
boards and delicate structures.
• Do not clean the device with strong chemicals, detergents or strong detergents.
• Do not apply the device with paint. Smudges might block in the device and affect the operation.
• Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also
explode.
All of 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 repair.
