NOTE
The display modes are identical to those
described in the chapter for dives with air.
NOTE
During the dive, when the button is
pressed, Puck Air will display the
estimated Deepstop 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.

WARNING
To fully understand how to perform
decompression with Ean, the user should
also carefully read the corresponding
section for compressed-air deco-stop dives.
NOTE
If you have completed an Ean dive and
wish to do a repetitive dive with air, set the
computer for “Ean” with O2 at 21%. By so
doing, the calculation of the %CNS will
remain active.
SAFETY STOP
If the maximum depth of a dive exceeds
10 meters, a “Safety Stop” is activated for the
ascent. Puck Air suggests that divers take
a 3-minute safety stop between 2.5 and 6 m
in depth (8 - 19 ft), and will display the word
“SafeStop.” A timer indicates the time needed
to complete the stop.
If the diver moves outside the depth range
mentioned above, the safety stop timer is halted.
When the diver re-enters the correct depth
range, the safety stop timer resumes from
where it left off.
If the diver returns to a depth below 10 m
(32 ft), the “safety stop” timer will ignore the
previously aborted stop and will start over
from zero. In the case of a decompression-stop
dive, the safety stop extends the duration of
the decompression-stop at 3 m (10 ft) by an
additional 3 minutes, displaying the safety stop
information as described previously.
DIVE  EAN: SURFACING
When the measured depth is less than 1 m
(3 ft), Puck Air considers the dive to be
suspended (“Surfacing”) and halts the dive
timer. If the diver does not return below 1.2 m
(4 ft) within the next 3 minutes, Puck Air
considers the dive to be finished and records
its data in the Logbook. If the diver does re-
descend within 3 minutes, the dive continues
and the dive timer resumes from where it left
off. Data displayed in Surface mode (Figure 52):


WARNING
If an Air or Ean dive ends with an
uncontrolled ascent or an omitted stop
, Puck Air will restrict Air and Ean modes
for 24 hours and will only allow the Bottom
Time operation mode.
NOTE
The backlight function is operational in
surface mode.

WARNING
Do not fly or travel to high altitudes while
the no-fly icon remains active.
DIVE  EAN: SURFACE MODE
When Puck Air considers the dive to be
concluded, it moves from Dive mode to Time
mode, showing the desaturation time and
the No fly icon. In addition, Puck Air displays
the icons for any errors made during the dive
(omitted stop, uncontrolled ascent).
Press the button to display the No fly time,
the SURF Time, and the %CNS.
Press the button to move to the Esc position.
Press and hold the button to exit this menu
and return to the main menu.
DIVE  BOTTOM TIME GAUGE
In this mode Puck Air functions as an
electronic timer and depth gauge, but does not
perform any calculations for no-deco limits
or for deco-stop times. Responsibility for
planning the no-decompression limits or an
adequate decompression therefore lies entirely
with the user.
The details displayed in Predive and Surfacing
modes are the same as those already
described for air or Ean dives (Figure 53):
