I need advice please. since service I've done 3 dives on my unit, shallow dives to 15m for a total dive time of 229 minutes. Incerted new cells with a total time of 136 min.
This weekend on my 2nd dive at the safety stop my handset suddenly showed cell 1 FAIL, however the hud kept on displaying PO2 value, did not show cell failure. Once home I've 1st changed the cells around but got the same error message. I've replaced the wiring with brand new ones and still got the same.
So from the two variables I know neither worked, I have not tried to recalibrate the unit, would that be my next step in fault finding? I've also send Hollis an email but I'm reaching out to the community as well. New to this and need to learn.
What buggs me as well is the other two cells are showing .35 in normal air, was never this high and used to mainatin .21. Could it be because of the new cells. They were left out for 48 hours before they were placed in the unit and calibrated. Dived another 12 hours after that.
It is a Hollis Prism 2 unit, please I'm looking for constructive help.
