has anyone cleaned the contacts on the wrist buttons? have a infinite 2.0 last serviced by hexagon 6 yrs. ago. very high humidity this summer and after initial start up and calibration all wrist buttons will not work. after I get it working, when I get pulled away for a hour to work on a rush job, when I get back to the romer the wrist buttons again do not work. have not had any major problems till now. has anyone had similar problems?
