If the unit did not display a Low Battery Condition prior to
entering the Dive Mode, and a Low Battery Condition
occurs during the dive, there will be sufficient Battery
power to maintain unit operation for the remainder of that
dive. The Battery Indicator will appear after the dive upon
entry into Surface Mode.
When the Battery is removed, settings and calculations for
repetitive dives will be retained, if a new battery can be
inserted within 8 seconds. Otherwise the calculations will
reset to zero and settings must be reset.
FO2 MODE
After Activation, the Pro Plus 2 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 with an FO2 value of 'Air' (Fig. 10), the Pro Plus
2 will perform calculations the same as if FO2 were set for
21% oxygen, internally accounting for oxygen loading for any
subsequent Nitrox dives. However, oxygen related displays,
warnings, 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 - 50).
