1. Position the object in the path of the beam.
2. Press both buttons simultaneously (for approx. 2 seconds) until the yellow LED flashes = object in focus.
In the event of button activation of less than 2 seconds, the Teach command is not effective, therefore providing no protection against further unwanted
manipulation.
3. Release buttons; yellow LED illuminates continuously = object is positively detected.
4. Fine adjustments can be made to the scanning distance, when required by the application: Pressing the "+" button (approx. 0.5 sec) = scanning distance will
be increased. Pressing the “–” button (approx. 0.5 sec) = scanning distance will be decreased. In the event of button activation less than 0.5 sec, no change
to the scanning distance is made. Upon activation of the button, the yellow LED flashes.
5. The Teach-in scanning distance is stored in the memory.
