Decompression Dives - Suunto Favor Air User Manual

18
- the ceiling descends to 12 m [39 ft]. A permanent error warning Er appears. In this
mode the FAVOR AIR can only be used as a depth gauge and timer.
The permanent ERROR MODE is shown by a non-blinking Er in the center of the
display. Once in ERROR MODE, the FAVOR AIR will continue to display current depth
and dive time. You should immediately ascend to a depth of 3 to 6 m [10 to 20 ft] and
remain at this depth until air supply limitations require you to surface. When the surface
has been reached, no further diving or flying should take place for a minimum of two
days.

3.4.5 Decompression dives

WARNING!
DO NOT USE THIS INSTRUMENT TO CONDUCT DECOMPRESSION DIVES!
Suunto does not recommend this instrument to be used to conduct decompression
dives. However, if through carelessness or emergency a diver is forced to exceed the
no-decompression limits on a dive, the FAVOR AIR will provide decompression
information required for ascent. After this the FAVOR AIR will continue to provide
subsequent interval and repetitive dive information.
Rather than requiring you to make stops at fixed depths, the FAVOR AIR permits you to
decompress within a range of depths.
Background
When your NO DEC TIME becomes zero, your dive becomes a decompression dive,
i.e. you must perform one or several decompression stops on your way to the surface.
The NO DEC TIME on your display will be replaced by a flashing notation
CEILING/ASC TIME.
WARNING!
YOU SHOULD ASCEND AND BEGIN DECOMPRESSION IMMEDIATELY WHEN
THE FAVOR AIR SHOWS YOU THAT DECOMPRESSION IS REQUIRED!
Note the upward pointing arrow.
The ascent time (ASC TIME) is the minimum amount of minutes needed to reach the
surface in a decompression dive. It includes:
The time needed to ascend to the ceiling at an ascent rate of 10 m/min [33 ft/min],
plus
The time needed at the ceiling. The ceiling is the shallowest depth to which you should
ascend,
plus
The time needed to reach the surface after the ceiling has been removed.
WARNING!
