This mode is intended for use Liberty as bailout CCR device, with another CCR used as main device. In this mode the oxygen is not injected, only the loop volume is adjusted by ADV. Decompression model is updated, where ppO2 equal SP is expected. Diluent from the other device must be configured as "2nd device diluent". When fraction O2 in the loop drops below O2 fraction in diluent (i.e. the diver probably breathes from this device), the standard CCR mode is selected automaticaly.
GF handling bound with mode change is now smarter. Mode change CCR -> OC, Bailout GF is selected Mode change OC -> CCR, Standard GF is selected GF manually switched to Bailout GF remains active until manually switched to Standard GF.
Setup / Preferences / Timeouts / Prebreathe time min, default 5 min If set nonzero, timer starts count down as a last step in dive check list. This feature is independent whether check list is enabled or not.
Feature must be enabled and multiuser capable HS used (licence for HS needed and bootloader version at least 3.10.0) Left handset stores the profile of the user
If all chemical sensors fail in dive mode, an alarm "pO2 measuring lost" is raised. If the diluent contains at least 20% He, it is possible to switch the pO2 source to He measuring. Setup / Faulty sensors / pO2 source, options "O2" or "He". Automatic switch is no longer suppoorted. When the He source is selected, all pO2 fields on handset screens have blue background and "pO2 indirect" message is on the base screen. The pO2 indirect field on the technical screen (with sensors) has always blue background, as it shows "pO2 from He" everytime. The %He field on the technical screen become dashed for both sensors, as %He calculation is invalid in this mode.
If all chemical sensors are not valid (error, disabled etc.), the depth is < 6m/20ft and the pO2 source is O2 sensors, an emergency O2 injection + alarm is done every 6s. In fact, Liberty become an oxygen rebreather (6m / 20ft depth is safe for pure oxygen). This action happens also in Surface mode.
This version was not officially released, all changes are made public in next version.
