If Subgear XP-3G is displaying a decompression obligation when you reach the PDIS depth during an
ascent, all rules apply the same way, but the 2-minute countdown runs in the background and is not
displayed on the screen. The PDIS label however will still be blinking to show you that you are in the
PDIS range.
