Setting Sensitivity

If you can hear the Scarecrow's clicks from 10 meters (35 feet)
away, you do not need to turn on the water for this section. In a noisy
area where the audible clicks cannot be heard each time you move, please
turn the water on for setup purposes. If you decide to turn the water on for
your setup process, just point the water spray to one side to avoid getting wet.
1. Turn the sensitivity knob on.
Sensitivity Knob
RESET / OFF
Set the sensitivity knob high enough to see to target animal
when it is within reach of the 10 meter (35 foot) water spray, but not
beyond that point. It is not beneficial to sense animals or moving
objects outside the area you wish to protect.
2. Confirm sensing area.
Start outside your desired coverage area and work your way inwards.
The Scarecrow's sprinkler will activate once it detects you. Make minor
adjustments until you feel the Scarecrow will only trigger when
movement is detected inside the you wish to protect. After the 3 second
pulse of water, remain still for approximately 8 seconds after each
activation, while the Scarecrow resets itself. Repeat this process until you
have a good idea of the Scarecrow's area of coverage at this setting.
3. Increase or decrease the Scarecrow's sensitivity

Adjusting Water Coverage.
After you have set the Scarecrow's sensitivity and positioned it securely
with its lens aimed at the desired area, use this section to help you adjust
the arc and distance of the Scarecrow's water spray.
Make sure the water is turned OFF, then follow the steps below.
1. Position stem tabs to adjust sprinkler travel.
Position the stem tabs so the metal wire clip travels between these tabs
and faces the area to be sprayed. Stem tabs determine the arc range of
the Scarecrow from 0 to 300 degrees.
Wide tabs produce wide arc.
