Open Toolbox APP and go to “Device ->Setting -> LoRaWAN Settings” to change the frequency
and channels.
Software Configuration:
Log in Toolbox and go to“LoRaWAN Settings -> Channel”to change frequency and channels.
Note: If frequency is one of CN470/AU915/US915, you can enter the index of the channel that you
want to enable in the input box, making them separated by commas.
Examples:
1, 40: Enabling Channel 1 and Channel 40
1-40: Enabling Channel 1 to Channel 40

EM300 Series User Guide

4. Installation
1. Attach EM300 to the wall and mark the two holes on the wall. The connecting line of two holes
must be a horizontal line.
2. Drill the holes according to the marks and screw the wall plugs into the wall.
3. Mount the EM300 to the wall via mounting screws.
4. Cover the mounting screws with screw caps.
5. For leak detection senor, install the probe/cable to the place where liquid may leak. For magnet
switch sensor, install the magnet beside the door/window.
Note: For SLD sensor, please ensure the metal pins of the probe are flat on the floor; for ZLD
sensor, the cable can’t be twined or accumulated together. The probe or cable of water leakage
sensor should be placed in an area of concern where water from a leak would likely accumulate.
5. Milesight IoT Cloud Management
EM300 sensors can be managed by Milesight IoT Cloud platform. Milesight IoT cloud is a
comprehensive platform that provides multiple services including device remote management
and data visualization with the easiest operation procedures. Please register a Milesight IoT
Cloud account before operating following steps.
