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 2m 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) Sensor's microwave can penetrate wall of building. It may cause misreport when microwave penetrates
wall to detect the moving objects outside fortified area. To avoid triggering by mistake, choose suitable place
when installing, keep away from glass, plasterboard, wooden wall and other things that microwave can easily
penetrate and choose appropriate sensing parameters according to space, for examples:
A. When product is used in the room whose length and width is about 2m or less, detecting area should
be set to 25%(application scenario: washroom, sitting room )
B. When product is used in the room whose length and width is about 3m, detecting area should be set
to 50%(application scenario: washroom, hallway, sitting room )
C. When product is used in the room whose length and width is about 4m, detecting area should be set
to 75%(application scenario: small office, meeting room, library )
D. When product is used in the room whose length and width is about 5m or more, 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
application scenario are for reference only).
8) Hold time setting: one-person space: 1 minute to 3 minutes, multi-player space: 30 seconds to 1 minute. It is
not recommended to set a hold time of more than 5 minutes to be probably interfered by small motion signals in
the space and affect the hold time finishing.
