Programming garage openers with Dip switches
I have a 3 button sears garage door opener (HBW1D3469). It says in the instructions that I can program one of the extra buttons to open a second garage door - which would be great because I have two independant doors. However, instructions then say to set dip switches to match the switches on the back of the opener itself - which I did. Voila, it opens my garage door. Question is, how do I program it to open the other door, which has switches set in a completely different pattern???
