1. Press and hold TEACH for longer than 2 seconds to start the selected TEACH mode.
2. Present the target.
3. Press TEACH to teach the target. The target is taught and the sensor waits for the second target, if required by the

See the Instruction Manual for detailed instructions and other available TEACH modes.
Manual Adjustments
Manually increase or decrease gain using or .
1. From Run mode, press either or one time. The current signal strength value flashes slowly.
2. Press
to decrease the sensor's gain or to increase the sensor's gain, or press and hold or to rapidly
decrease or increase gain. After 1 second, the normalized signal strength flashes rapidly, the new setting is
accepted, and the sensor returns to Run mode.
Locking and Unlocking the Sensor Buttons
Use the lock and unlock feature to prevent unauthorized or accidental programming changes.
