Overhead door model 556 sensitivity training

With the above model I have recently experienced failure of closure of the door with return to open position. I have no manuals as the unit was present when I bought my home. I have identified the LED's with buttons F+ and F-; how may I adjust these correctly to allow the door to close?

I would greatly appreciate any help.

Regards,
