Oceanic OC1, Руководство по эксплуатации, Страница: 87 / 180

87
FO2 Gas 1 will continue to reset to the FO2 50% Default after subsequent repetitive dives
until 24 hours elapse after the last dive, or the FO2 50% Default is set Off.
When the FO2 50% Default is set Off, the OC1 will remain set at the last FO2 Gas 1 Set
Point for that period of activation.
FO2 set to Air
The default FO2 Gas 1 each new dive period will be Air. When FO2 Gas 1 is set for Air,
calculations are the same as when FO2 is set for 21%. When FO2 Gas 1 is set for Air, it
will remain set for Air until set for a numerical FO2 value (21 to 50%).
When FO2 Gas 1 is set for Air, the O2BG will not be displayed at any time during the
dive, on the surface, or during the PDPS. PO2 will not be displayed during the dive.
MOD will not be displayed on the FO2 set screen when Air is displayed.
Internally, the OC1 will keep track of the oxygen loading so that if FO2 for Gas 1 is sub-
sequently set for Nitrox, the oxygen loading for previous Air dives will be accounted for in
the next Nitrox dive (during that dive period and series of repetitive dives).
FO2 set for Nitrox
When FO2 for any Gas is set for a numerical value, the dive is considered Nitrox and the
Nx icon will be displayed.
Once FO2 Gas 1 is set for a numerical value (21 to 50%), the Air option is disabled until
24 hours elapse after the last dive.
