I recently had to reset my OBi200 to get voice mail working again and VestaLink's instructions called for first depressing the button on the bottom of the OBi and THEN plugging in the AC adapter. Not the first time I have reset a device pressing a reset button, but the first time with an OBi. This proved really awkward trying to juggle a paper clip and perform the function with only two hands.
I thought someone else might benefit from how I made this easier. I took a push pin and snipped the pin down to about 1/4 inch, so that it was pretty much flush with the opening when I pushed it in. Doing this made it much easier to hold the pin and the OBi with one hand, while pushing in the AC cord with the other.
I was then able to stop cussing.
