should ascend

• the time needed to reach the surface after the ceiling and safety stops have been
completed.
WARNING YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN
DISPLAYED BY THE INSTRUMENT! The ascent time will increase
if you:
• remain at depth
• ascend slower than 10 m/min [33 ft/min]
or
• make your decompression stop deeper than at the ceiling.
These factors will also increase the amount of air required to reach
the surface.
