- By entering a non-zero value in the "CC set point" column of the
dive planner points table that segment is assumed to use a closed
circuit rebreather (CCR) with the given set-point for oxygen partial
pressure. If the last manually entered segment is such a CCR
segment, the decompression phase is also computed assuming the diver
uses a CCR with the same set-point. If the last segment (however
short) is on open circuit (OC) indicated by a zero set-point the
decompression is comuted in OC mode. The planner only considers gas
changes in OC mode.
