Atmos AI cleaning

Hi, i just starting using my new Atmos AI and had a question that the manual strangely does not address.

I have the QD option and after a dive, with the the computer disconnected from the hose, noticed some salt/grit/sand at the QD opening on the computer itself, around the small o-ring.

Can I dunk the computer in water with it disconnected? Does the computer have to be connected to be cleaned? Should it also be pressurized?

And what about the hose? If I am cleaning the regulator, unpressurized, with the computer disconnected, can I dunk the HP hose in water?

Thanks for your help. Love the computer so far!

I have the same unit for a year and really like it. I would ask the dealer you bought it from or atmos directly, however if you wiped it down or dunked it with the opening down in fresh water you should be ok.
