So how does it work?
Hey Guys,
Here is a quote from another forum from Jerry Whatley:-
"The new HUD uses two single color LEDs for PO2 display. The LED facing the diver is always red and the vertical LED is always green. The blink pattern is identical to the old LED other than at a PO2 of 1.0 both LEDs blink.
This change was to accommodate color blind divers and difficulty in determining color in high ambient light conditions."
