I've a trouble with the pressure Piezzo button. I haven't been diving this winter and when I get out my OSTC the Left button is hard to use and the right is unresponsive.
With this problem I can just start the Divecomputer but I can't use it. So I can't change the button sensivity. And I can't conncect it to my Macbook to activate the bluetooth.
Same problem here, right side button unresponsive. Not nice when I couldn't change the fixed set point on it ( a back up computer), while the other one OSTC CR decides to calculate deco on a deep dive with a ppO2 of 0.00 (one cel reading different than the others)
