the dive screen.

You have the option to purchase a PIN to activate this feature. When this mode is
enabled, you can gain access from the Home Screen, (toggle through the mini-
screens). Gas Calculator mode will allow you to work out partial pressure gas fills on
your VR.
To find out what gases you need to add to adjust a gas mix, enter your current
cylinder fill in the HAVE column and the gas mixture you need in WANT. The ADD
BAR column will automatically show the fill pressures to add.
