SCROLLING OF NO
DECOMPRESSION LIMITS
Fig. A shows the different ways for accessing SURF
mode, i.e by pressing the <Mode> button from
CLOCK mode or by pressing the <-> button from
SIMUL mode.
This function allows the user to scroll through the
no decompression limits, automatically taking into
account the current residual saturation of his body
tissues from the preceding dive.
If a "Nitrox" dive is selected, the computer also
takes into account the percentage of O2 and the
max PPO2 settings.
To enter PLAN mode, press the <Mode> button for
2 seconds (fig. D).
Scrolling is started by pressing the <Mode>
button, the computer displays (fig. 33):
Depth.
No decompression time remaining expressed in
minutes.
FIG. 33
Repeatedly press and release the <-> button to
increase the depth by three meters (9.8 feet) each
time, up to a maximum of 48 m (157.4 ft). For
each depth, the display shows the corresponding
no decompression time remaining expressed in
minutes.
Instead, if the two buttons are pressed
simultaneously, the computer exits PLAN mode.
If "Nitrox" mode is active, the display shows the
programmed % of O2 (fig. 34).
