Today during dive at 20m, after about 5 minutes my OSTC4 was start to fast scrolling display from left to right. After a few seconds of scrolling display hangs and was start to dimming to totaly blank. Only backlight was be shown. Non response to buttons. And afer another 10 minutes, as sudenly as it apears, display turns to normal activity. Log aperas to be continous.
What hapened? What I can trust such computer?
Next dive, same problem.
Today @ 23m, 9' of dive display was switched off. After another 15' it starts fast scrolling at normal brightness. After few minutes of scrolling switch to normal status and works fine to the end of the dive (76').
