I recently ordered an almost brand new Viso 2 altimeter off site. When I got it it would not turn on, so I took it out of its rubber case it was covered in sticky glue. I looked it up online and apparently the glue that binds the plastic pieces together can seep out. Does anyone have any tips for fixing it and getting it to turn on? I ordered new batteries to try and put that in since those are way cheaper than a new unit.
