Aladin 2G vs Aladin Tec 2G

[Alessandro Caruso]

Hi everyone, 

I own a Uwatec Aladin 2G dive computer. 

When I try to import the stored dives, the software adds it as an Aladin Tec 2G. 

After importing the dives, if I select one, the following message appears at the bottom: "Dive: 0, dive computer: Uwatec Aladin Tec 2G: open circuit dive, but no open circuit cylinder found. Please add or select the correct cylinder use." 

How can I fix this? 

Thanks.

Alessandro

Both models share the same model number, so we can't distinguish them.

Thanks for the reply. 

Regarding the message "Dive: 38, dive computer: Uwatec Aladin Tec 2G: open circuit dive, but no open circuit cylinder found. Please add or select the correct cylinder use," it appears even though I have selected the cylinder in use (I am attaching an image). 

How can I resolve this?

I should clarify that I am using the latest development release (CICD): 6.0.5680.

Thanks,

Alessandro

The error message appears as the cylinder for this dive has 'Uso' of
'non usato', meaning that Subsurface was set to assume that this tank
was not used during the dive.

I have never seen this happen for any cylinders imported from a dive, or
heard any bug reports about this. Could it be that you accidentally
changed this when you added the start and end pressures?
