When PO2 reaches a value of 1.60 ATA, or the PO2 Alarm Set

Point (a user setting), the red LED warning light will flash, the

Audible Alarm will sound (unless set OFF), and the current PO2

and the Bar Graph, Transmitter Link icon, Current Depth, and

HIGH OXYGEN ACCUMULATION

The O2 Bar Graph displays either oxygen accumulated during that nitrox dive, or during

the repetitive nitrox dives you conduct during that 24 hour period, whichever of the two is

greater at that time.  The O2 Bar Graph offers you a convenient way to monitor how close

you are coming to the limits of oxygen exposure.  Use it as a visual reference to

place a wider margin of protection between you and the Limits.
