NOTE
When the Deepstop icon appears, pressing
the button will display the estimated
stop required. The data displayed during
the ascent may vary as a result of the
diver’s behavior. Divers should check this
data during the ascent for more precise
information on the estimated stop.
NOTE
When the no-decompression time
remaining is one minute, an audible alarm
is sounded to indicate that the diver is
about to exceed the no-decompression
limits.
DIVE  AIR: “DECOMPRESSION
STOP” DIVE
If the diver does not ascend when the residual
time has expired, Puck Air switches to
“decompression-stop” mode, indicated by the
appearance of the “dec” message and by an
audible alarm.
The following data are displayed in this mode
(Figure 39):

TIME TO SURFACE ASC TIME
The ascent time is given by the sum of:
• the durations of the various
decompression-stops
• time required to ascend at an average speed
of 10 m/min (32 ft/min)
• any Deepstops.
DECOMPRESSION STOPS
Puck Air will also check that the
decompression-stops have been observed; two
icons graphically indicate what action the diver
should take (Figure 41):
Fig. 41
• 2 triangles: correct decompression-stop
depth
• upward triangle: diver below
decompression-stop depth, ascend!
• downward triangle: diver has ascended
beyond decompression-stop depth, descend!
 WARNING
When the omitted deco stop alarms are
triggered, desaturation of the simulated
tissue compartments is halted and
resumes only when the diver returns to
the correct stop depth.
If the decompression-stop depth is exceeded
by more than 30 cm (11 inches), the
“downward triangle” icon will flash; if it is
exceeded by more than 1m (3 ft) the icon keeps
flashing and an audible alarm will sound.
These warnings remain active until the diver
returns to the correct depth.

WARNING
Never ascend above the correct
decompression-stop depth.
NOTE
If the deco-stop overshoot exceeds one
meter and lasts more than three minutes,
the computer switches to “Omitted Stop”
mode and the corresponding icon appears.
In this case, if after surfacing the diver
attempts a repetitive dive, Puck Air will
only function as a depth gauge and timer
(BT mode), and will display the errors of
the preceding dive.
DEEPSTOP
To minimize the likelihood of critical bubble-
seed formation, in the case of decompression
dives or dives close to the no-deco limit,
