Sensor not detecting movement

Check the following

Range adjustment is set too low and adjust range if needed.
Angle of sensor on mounting arm is too steep and adjust sensor angle if needed.
Object in front of sensor is moving and producing heat.
Intelligent Sensing increases the delay between activations. Deactivate Intelligent Sensing mode if desired (see Intelligent Sensing section).
There is dust, dirt or hard water build-up on the white lens which will limit sensitivity. Wipe the lens gently with a damp cloth if needed.

(If you do have high-pressure Orbit® recommends adding a pressure reducer to increase hose life).

Maximum: Do not operate at temperatures exceeding 120°F
Minimum: Keep from freezing. To prevent damage from freezing water, take the Yard Enforcer™ inside and remove the battery before the first winter frost.

For outdoor use with cold water only.
Improper setup or use of sprinklers increases the risk of water damage to property.
Limit the supply of water to the sprinkler by opening the valve to a 3/4 turn position.
Use high-quality hoses and maintain pressures within the working pressure range stated above.
Install a pressure reducer if you have high pressure from the hose faucet.
Only opening the tap part way does NOT lower water pressure.
Use the step on the stake when pushing into the ground.
Do not apply pressure or weight on the sensor housing or sprinkler.
