YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DISPLAYED BY THE
FAVOR AIR
The ascent time will increase if you:
- remain at depth,
- ascend slower than 10 m/min [33 ft/min], or
- make your decompression stop deeper than at the ceiling.
These factors will also increase the amount of air required to reach the surface.
WARNING!
NEVER ASCEND ABOVE THE CEILING!
You must not ascend above the ceiling. In order to avoid doing so by accident, you
should stay slightly below the ceiling. The ceiling zone is the shallowest depth range to
which you should ascend when in decompression.
Display Below Ceiling Zone
The CEILING/ASC TIME symbol and upwards pointing arrow indicate that you are
below the ceiling zone. You should start your ascent immediately.
Display At Ceiling Zone
When you reach the ceiling zone, the display will show you two arrows pointing toward
each other. The two arrows pointing toward each other will be shown between the
minimum ceiling and 1.8 m [6 ft] below the minimum ceiling. All decompression stops
must be performed at or below the ceiling depth range.
The depth of the ceiling will depend on your dive profile. It will be fairly shallow when you
enter the decompression mode, but if you remain at depth, it will move downward and
the ascent time will increase.
The ceiling depth will be shown on the left side of the center window.
When the sea 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 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.
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.
