M380 living room slide

[sizzbiz2]

The living room slide on our M380 has decided to stop half way out. It will
retract, but only go out half way. I have checked for obstructions, but haven't
found any. I am thinking that maybe if I hit the reset button it will correct
itself. Problem is that I can't find the button. I know it is located behind the
key switch panel, but don't see anything that looks like a reset button.
Has anyone had this problem and can you help me locate the reset switch.
Thanks.
