POST DIVE SURFACE MODE
When you ascend to 3 feet (1 meter) or shallower, the 500AI will enter Surface
Mode and begin counting your surface interval.
TRANSITION PERIOD
The first 10 minutes is, in affect, a Transition Period during which time the
following information is displayed (Fig. 47):
• 'Number' of that dive
• Surface Interval (colon flashing) and icon (flashing).
• Tank Pressure (digital display and Bar Graph)
• Nitrogen Bar Graph indicating current nitrogen loading.
• O2 Bar Graph indicating current oxygen loading (if a nitrox dive)
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.
To view the Temperature/Time/Date (Fig. 48):
• press the Advance (Left) button 1 time
• the unit will revert to Surface Mode after 10 seconds
