Mechanical Adjustments
A.
THE WIDTH OF THE SENSING FIELD IS DETERMINED BY THE CHOICE OF THE PLANAR ANTENNA (OPTION)
Wide sensing field:
3-element antenna
Carefully remove the
protective cover of the antenna
with a screwdriver.
B.
THE POSITION OF THE SENSING FIELD IS DETERMINED BY THE VERTICAL TILT ANGLE OF THE ANTENNA
Sensing field as close to the door
as possible:
-antenna set at the position of 0°
