Section 2: Diving with the Monitor 3 Air

24

Total Ascent Time

Total Ascent Time is the addition of all the decompression
stop times plus the amount of time it takes to ascend from
the current depth to the first decompression stop.

Note: Total ascent time is calculated with an optimal

ascent rate of 100% and normal workload. High workloads

and different ascent rates may change the total ascent

time.

SOS Mode

If you ignore your decompression stop and return to the
surface (shallower than 4 feet) for more than three
minutes, the Monitor 3 Air switches to SOS Mode. In SOS
Mode, the computer displays SOS instead of current
depth. While in SOS Mode, the computer cannot be used
for 24 hours. SOS Mode can influence the computer's
calculations for three days after the incident due to the
presence of microbubbles.
