WARNING
We recommend before you begin diving, 
you always put Puck Air into Predive mode. 
Early in your dive, always check that the 
dive computer is switched on.
NOTE
After a dive in “BT” mode, the transition 
to “Air” or “Ean” mode will be disabled 
for 24 hours (you can bypass this block by 
resetting the residual nitrogen in the tissue 
compartments in the Set Data menu).
 
WARNING
This option is intended only for highly 
experienced divers. Users who clear the 
residual nitrogen memory cannot then use 
the instrument for repetitive dives. After 
clearing the residual nitrogen memory, do 
not dive with Puck Air if you have already 
dived within the previous 24 hours.
NOTE
Hold down the button for 4 seconds to 
activate the display backlight. 
SURFACE MODE  BOTTOM TIME
The desaturation time and the delay before 
flying or traveling to high altitudes are 
displayed in the same way as for Air or Nitrox 
dives.
BOTTOM TIME WITH BEHAVIOR 
ERROR
The following errors can occur during an air or 
Ean dive:
•  uncontrolled ascent
•  omitted deco stop
In this case, Puck Air will inhibit the Dive – Air 
and Dive - Ean modes for 24 hours, allowing 
operation in Bottom Time mode only, and will 
continue to display the error committed during 
the previous dive.
PC LINK MODE 
Using a special interface unit and a dedicated 
Windows software application, you can transfer 
all the data from the Puck Air Logbook to a 
personal computer.
Puck Air and the computer communicate 
through a special USB interface module 
(optional).
Scroll through the main menu to PC 
(Figure 56).

LOGBOOK
Logbook mode is used for viewing the details 
of past dives on the display. The dives are 
organized as in the pages of a “Logbook” with 
the number “1” assigned to the most recent 
dive, “2” to the preceding dive and so forth 
until the memory is full. If the memory is full, 
when the user dives again the oldest record is 
deleted to free up memory for the new dive. 
Maximum capacity of approximately 40 hours 
of diving with profile points at twenty second 
intervals. Scroll through the main menu to 
Logbook. Press and hold the button to enter 
the Logbook. The first page of the Logbook 
contains the history of the dives saved 
(Figure 58):
