OSTC Plus won’t wake up

Post by jb2cool »

My girlfriend has an OSTC plus running the 10.57 firmware. She was looking through the logbook to fill out her logs. 15mins later I was going to change the logbook offset for her to make the numbers line up but it won’t wake up now.

I’ve sat it on the charger and the charger went solid green at first then changed to flashing green but still no activity from the dive computer.

I have had similar issues waking it up before but if I carried on poking it then it would wake up before.

What am I doing wrong?

Hi,

normal procedure to awake an OSTC from deep sleep is to turn it upside down (i.e. screen pointing to other direction than before) and wait a few seconds, then pressing a button. If that doesn't work, we'll need Matthias advice...

Pretty sure I had it in every orientation and nothing. I ended up taking the battery out and then reinserted it again and it’s now alive again.

Hi,

please check if the compass calibration (The compass is been used in sleep mode to detect movement) works.

regards,

I will keep an eye on it. I recalibrated the compass last night after seeing your message so will see if this happens again.

Did you try just using a standard AA battery instead? It could be as simple as a totally flat battery.

Since recalibrating and subsequently updating my firmware this computer has been fine for us.
