Oceanic Personal Dive Computer Veo 100Nx - Manual (Page 15)

FO2 MODE
After Activation, the Veo 100Nx will operate as an AIR com-
puter without displaying information associated with oxygen
calculations, unless it is set for a percentage of oxygen (FO2)
other than AIR (a numerical value between 21 and 50 %).
When set for an FO2 value of AIR (Fig. 9), the Veo 100Nx
will perform calculations the same as if FO2 were set for 21%
oxygen, internally accounting for oxygen loading for any subse-
quent Nitrox dives. However, oxygen related displays, warn-
ings, and the O2 Bar Graph will not appear on the display for
that dive, or subsequent dives, unless FO2 is set for a numerical
value (21 to 50).
Once a dive is made with the unit set as a nitrox computer (FO2
set for a numerical value), it cannot be programmed to operate
as an AIR computer until 24 hours after the last dive. AIR will
not be displayed as an option in the FO2 Mode. However, you
can set FO2 for 21% for use with AIR.
When FO2 is set at a value of 21% (Fig. 10), the unit will
remain set at 21% for subsequent nitrox dives until FO2 is set to
a higher value, or until it automatically turns Off and is reacti-
vated.
Setting FO2 is described on Page 21.
