2. Product Function
Walk Mode: a large movement (walking) of the human body.
Leisure Mode: only small motions of the human body, such as forward, backward, limb swing, head shaking, typing, playing with mobile phones, and other minor actions.
Presence Mode: only detects human breathing within the 30S (abdominal cavity, thoracic cavity expansion behavior actions), no significant movement is detected.

8. Installation Instruction
9. Application Notice
1) The sensor should be installed by a professional electrician. Please disconnect the power before installing, wiring, or changing the setting of the dial switch.
2) Put the sensor as far as possible from large areas of metal plate, glass, and other materials with high medium density to avoid triggering by mistake.
3) Avoid using objects that have been vibrating for a long time around the sensor, such as shaking fans, etc. The vibration signal will be regarded as the motion signal to trigger the sensor.
4) Avoid the detection window of the daylight sensor of the detector irradiated by an invalid light source, which will interfere with the measurement of ambient light.
5) The product should not be too close to the wireless router at least more than 0.5m apart, when it is installed and used.
6) Setting detecting area and indicator on-off by MH10.(Pressing HS in MH10 makes indicator on and pressing LS in MH10 makes indicator off.)
7) The microwave can penetrate the wall of the building. It may cause misreport when a microwave penetrates the wall to detect moving objects outside the fortified area. To avoid triggering by mistake, choose a suitable place when installing, keep away from glass, plasterboard, wooden walls, and other things that the microwave can easily penetrate, and choose appropriate sensing parameters according to space, for example:
A. When the product is used in a room whose length and width is about 2m or less, the detecting area should be set to 25% (application scenario: washroom, sitting room )
B. When the product is used in a room whose length and width is about 3m, the detecting area should be set to 50% (application scenario: washroom, hallway, sitting room )
C. When the product is used in a room whose length and width is about 4m, the detecting area should be set to 75% (application scenario: small office, meeting room, library )
D. When the product is used in a room whose length and width are about 5m or more, the detecting area should be set to 100% (application scenario: large office, meeting room, library )
Note: The setting detecting area depends on the actual environment (detecting area parameters above the application scenario are for reference only).
8) Hold time setting: space of one person: 1-3 minutes, space of more than one person: 30 seconds to 1 minute. It is not recommended to set a hold time of more than 5 minutes, to avoid the small motion signal in the space from interfering with the hold-time closing.
