NOTE: To make it easier to understand
the menu system in accordance
with your current level of diving, the
G2 has a feature upgrade function.
More advanced level functions and
selections do not appear in the menu
unless you want them to. (This is why
you might find some menu numbers
missing from the MAIN menu screen.)
For example, if you are not diving with
rebreathers or using more than one gas,
it's not necessary to enable the CCR or
PMG menu modes. This keeps the menu
system simple and streamlined to suit your
particular diving style.

The factory setting is 1.40bar.
The MOD limit defines the warning depth
based on oxygen toxicity. However, depth
narcosis can affect a diver's skills much
earlier, jeopardizing his or her ability to dive
safely at that depth.
