FIG. 35
DIVE  BOTTOM TIME GAUGE
In this mode Nemo 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.
Displays in PREDIVE and SURFACING modes
are the same as those seen earlier for AIR or
EAN dives.
DIVE  BOTTOM TIME
The data displayed in DIVE mode are shown in
figures 36 and 37.
FIG. 36
FIG. 37
NOTE
After a dive in BOTTOM TIME mode,
switching to AIR and EAN mode is
suppressed for 24 hours. (This lockout
can be disabled by clearing the residual
nitrogen memory in SET DIVE - DATA
mode.)
 WARNING
Users who clear the residual nitrogen
memory cannot then use the instrument
for repetitive dives. After this operation, do
not dive with Nemo Air if you have already
dived within the previous 24 hours.
DIVE  BOTTOM TIME: SURFACE MODE
The desaturation time and the delay before flying
or traveling to high altitudes are displayed in the
same way as for AIR or EAN dives.
BOTTOM TIME WITH BEHAVIOR ERROR
The following errors can occur during an AIR
or EAN dive:
• uncontrolled ascent;
• omitted stop.
In this case, Nemo Air will inhibit the use of
AIR and EAN modes for 24 hours, allowing
operation in BOTTOM TIME mode only, and will
continue to display the underwater behavior
error from the previous dive.
The icons corresponding to the error
committed will be displayed in DIVE, TIME and
LOGBOOK modes.
