Hi,
With 0.21bar as the threshold you'll see ppO2 low warnings on the surface since the alarm is shown when 0.209 is reached and the pressure reading is <1000hpa. Bear in mind that the displayed surface pressure is artificially stabilized and only an average value is displayed. This prevents the ...

Hi,
Do you see these errors on the dive computer screen, too?
There really is no known issue with the ppo2 warnings in the 3.26 and we do not see such errors during our weekly diving at all.
regards,
Matthias

The checksum is historically the checksum of the English version of the firmware. So the file hwos_tech_firmware_EN.hex.
Here are the current MD5 checksums for the other versions:

Re: Ploywatch? Remove Scratches
Hi,
I doubt that you can remove the scratches properly from the glass. I think you should leave it as it is rather than trying to polish it with questionable means. A protective film may even help to fill these scratches. This will make them barely visible (Same refractive index then the glass ...
