Operation Manual

DataTrans Plus

Once 10 minutes have elapsed, the Surface Mode icon and Surface Interval

time display colon will stop flashing (Fig. 70) indicating that the dive and tran-

sition period are completed, and a subsequent descent will be considered a new

dive. Other information will continue to be displayed as described above and

you will have full access to the Mode Menu.

FO2 MODE

If the DataTrans Plus was set for FO2 of 'Air' or 21% prior to the dive, it will

stay set for 'Air' or 21%, respectively, unless you reset it to a higher numeric

value prior to the next dive. If it was set for a numeric value of FO2 greater

than 21% (22 to 50 %) prior to the dive, the FO2 value displayed after the dive

will be 50 % (Fig. 71) and subsequent dives will be calculated based on 50%

oxygen for oxygen calculations and 21% oxygen (79% nitrogen) for nitrogen

calculations, unless you set FO2 for another value.

Remember!! You must set the FO2 to match the specific nitrox mix

for each nitrox dive, even if the percentage of oxygen in the mix is

the same as the previous.

PLAN MODE

When you access the Plan Mode after a dive, the FO2 screen will show the FO2

set point value that you entered for the next dive. The PO2 screen will show
