Craftsman 1/2 HP Chain Drive Garage Opener

What are the factory settings for the Up/Down Limiter Switch? The opener is a model 139.53648SRT. The orientation of the up and down switches is evident in photos and diagrams of the limit switch but after tampering I want them back to the factory setting. Is there any way to do this? Thanks for any help.
