Fig. 3.18 Decompression dive,
at the ceiling zone. The two ar-
rows point at each other (“hour
glass”). You are at the optimum
ceiling zone at 3.5 m [11 ft]
and your minimum ascent time
is 5 minutes. By pressing the
TIME button you can display
maximum depth and time.
Fig. 3.19 Decompression dive,
above ceiling. Note the down-
ward pointing arrow and the
Er warning. You will also hear
an audible alarm. You should
immediately (within 3 minutes)
descend to or below the ceiling.
DISPLAY AT THE CEILING ZONE
When you reach the ceiling zone, the dis-
play will show you two arrows pointing at
each other (the “hour glass” icon, Fig 3.18). Do
not ascend above this depth zone.
During decompression, ASC TIME will count
down toward zero. When the ceiling moves
upwards, you can ascent to the new ceiling. You
may surface only when the ascent/Mandatory
Safety Stop time reaches zero and is replaced
by NO DEC TIME and when the CEILING
display disappears.
DISPLAY ABOVE THE CEILING
If you ascend above the ceiling, a downward
pointing arrow will appear and a continuous
beeping starts (Fig. 3.19). In addition, an
error warning Er reminds you that you have
only three minutes to correct the situation.
You must immediately descend to, or below,
the ceiling.
If you continue to violate the decompression,
the dive computer goes into a permanent Error
Mode. In this mode the instrument can only be
used as a depth gauge and timer. You must not
dive again for at least 48 hours (see also section
3.8. “Error Conditions”).
