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 O
2
at
21%. By so doing, the calculation of the
%CNS will remain active.
SURFACING – EAN
When the measured depth is less than 1 m
(3 ft), Puck 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 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 26):
• Duration of the dive
• Max depth
• Icons for any mistakes made during the
dive(omitted stop, uncontrolled ascent)
• Display of % CNS
FIG. 26
NOTE
The backlight function is operational in
surface mode.
SURFACE MODE – EAN
When PUCK 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 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 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
mode are the same as those already described for
air or EAN dives.
The data displayed in Dive mode are (Figure 27):
• Dive time
• Current depth
• Ascent rate
FIG. 27
Pressing the button will display (Figure 28):
• Temperature (in °C or in °F)
• The maximum depth reached
FIG. 28
Pressing the button again will display (Figure 29):
• Type of dive (BT)
