POST DIVE SURFACE MODE
When you ascend to 3 feet (1 meter) or shallower, the DataTrans Plus will en-
ter Surface Mode (Fig. 69) and begin counting your surface interval.
TRANSITION PERIOD
The first 10 minutes is, in affect, a transition period during which time:
• The main time display starts counting Surface Interval (colon flashing).
• The Surface Mode icon will appear (flashing).
• The Tissue Loading Bar Graph will indicate current nitrogen loading.
• The O2 bar graph will indicate current oxygen loading, if the dive was a
nitrox dive (FO2 set for a numerical value).
• Temperature and Time of Day will also be displayed.
If you descend during the 10 minute transition period, time underwater will be
considered a continuation of that dive. The time at the surface (if less than 10
minutes) will not be added as Elapsed Dive Time. During the 10 minute tran-
sition period, the Log Mode is accessible in the Mode Menu and will display
that dive's data, however, the data will not be stored in the unit's memory until
the 10 minute period on the surface is completed. No other modes are acces-
sible in the Mode Menu during the 10 minute transition period.
