DECOMPRESSION MODE:
Should a no-decompression limit be overstayed, the
COMMANDER will enter the Decompression Mode.
In this mode, the Ceiling digits will display the depth at
which the diver must stop and not ascend above
during final ascent. The “TEMP” legend and two digits
will be replaced with the “CEIL” legend and two digits.
The Ceiling will start at 10 feet and increase in ten-
foot increments as the diver remains at a relatively
deep depth.
The Remaining No-decompression Time and “NDC”
legend will be replaced with Decompression Time and
“DEC” legend (Figure 16d). Both STOP time and
TOTAL time are displayed in the upper left hand three
digits of the screen in hours and minutes. STOP and
TOTAL time will alternate at the rate of once every
two seconds. In this way, the diver can view the time
to spend at a particular STOP depth, and the TOTAL
time it will take to complete all STOPS. Clearly, the
larger of the two alternating numbers is the Total
Decompression Time of all stops, and the smaller of
the two numbers is the time required at the current
stop. At the ten foot stop, the TOTAL and STOP
times may be the same and therefore appear to not
alternate.
When at a specific stop, the required decompression
time at that stop is as shown, and will appear to count
down as it is recomputed every second, based on the
divers exact current depth. The Decompression times
(both Stop and Total) are accurate only if the divers
depth is exactly the same as the required Ceiling.
However, it is not necessary to be precisely at that
specified Ceiling. Appropriate In-gassing or Out-
gassing will be computed regardless of the divers
current depth.
