wire size. Observe proper polarity.
 Use Switch 3 to select the appropriate fluorescent
light filter (see Dip Switch Settings chart on the next
page).
 Apply power to the unit. Initialization is complete
when the LED stops flashing slowly.
 Adjust the microwave range to minimum setting
(25%) by turning the range adjustment counterclock-
wise using a small screwdriver.

 Begin walking through the detection area.
- The LED will turn red, indicating an alarm detection.
 Increase the microwave range as necessary.
 Repeat the items in step 5a until proper detection
range is obtained.
ºb Optional: Walk-test using Zone Finder.
 Use a screwdriver to short the test pads.
 During the Zone Finder walk-test mode, the LED
turns:
- green for one second for every PIR detection;
