SUUNTO FAVOR S - Manual (Page 34)

When the sea surface is rough, it may be difficult to maintain a constant depth near
the surface. In this case it will be more manageable to maintain an additional distance
below to the ceiling, to make sure that the waves do not lift you above the ceiling.
SUUNTO recommends that decompression takes place deeper than 4 m [13 ft], even
if the indicated ceiling is shallower.
NOTE: It will take more time and more air to decompress below the ceiling than at the
ceiling.
DISPLAY ABOVE CEILING
If you ascend above the ceiling, a downward pointing arrow will appear (Fig 3.16). In
addition a blinking 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 requirements, the dive computer goes
into a permanent ERROR MODE. In this mode (Fig. 3.17) you must not dive again
for at least two days. See also Section 3.6, Error Conditions.
During decompression, ASC TIME will count down toward zero. When the ceiling
moves upwards, you can ascend to the new ceiling. You may surface only when the
ascent time reaches zero and CEILING/ASC TIME is replaced by NO DEC TIME.
WARNING !
NEVER LET THE CEILING DEPTH DESCEND DEEPER THAN 9 m [30 ft].
When the ceiling is deeper than 9 m [30 ft], a blinking error warning Er will
appear and when the 12 m [39 ft] ceiling is reached the dive computer will go into
a permanent error mode.
Fig. 3.16 DISPLAYS AFTER VIOLATED
DECOMPRESSION DIVE
The blinking CEILING/ASC TIME symbol (a)
indicates that you have violated the ceiling for
more than three minutes or the maximum ceiling
depth of 12 m [39 ft] was exceeded. The
instrument will stay as a depth gauge and timer
for 39 hours 59 minutes = no fly time (b). After 2
hours 30 minutes surface interval time the no fly
time is 37 hours 29 minutes. In the dive planning
mode the Er warning is displayed instead of the
no-decompression time (c). You must not dive
again or fly for at least two days.
