Notice!
Do not adjust the microwave Doppler radar range higher than required. Doing so might cause
the detector to detect movement outside of the intended coverage pattern.
Microwave Doppler radar signals penetrate certain surfaces such as drywall, wood, and glass.
If the protected area is significantly smaller that the detector's nominal range, reduce the
microwave Doppler radar range so that it can still detect motion on the near side, but not on
the other side of the surface.

Adjustable microwave doppler radar sensitivity
The detector has a microwave Doppler radar sensitivity adjustment potentiometer. Use this
feature to adjust the microwave Doppler radar detection range, if necessary.
Notice!
The product ships with the potentiometer pre-set to meet the rated range. In most cases, you
do not need to adjust the potentiometer during the installation. You might adjust the
potentiometer, as instructed, to reduce the potential for false alarms or for very large rooms.
The following figure shows how to adjust the setting using the potentiometer. Turn
counterclockwise to reduce sensitivity.

If on the last walk test, you observe LED activity while walking outside the coverage area,
decrease the microwave Doppler radar range and repeat the walk test.
Place the detector body onto the base.
Walk test across the coverage pattern at its farthest edge, then several times closer to
the detector.
Start walking from outside of the intended protection area, and observe the LED.
Walk test from the opposite direction across the pattern to determine both boundaries.
The center of the pattern should be pointed toward the center of the intended protection
area.
Walk test the unit from all directions across the pattern to determine all the detection
pattern boundaries.
