Just had a Gateway installed and programmed the Harmony 1. The problem is that the OK button does not work neither do the page up and page down buttons. For model I typed in MP2150A/NR. Also tried thr Learning mode and still no go. What have I missedÉ
As kevinds has said, choosing MP2000 as the model number should work for you. This model has been around longer giving Harmony time to work out any bugs in how they map the controls. The difference between the models is a hardware change, as they carry the same guide you should not see any negative effects.
