Change Note hwos Firmware 3.09.4 ================================ - When diving in CCR or pSCR mode: An attention and a warning for the gas density has been added. The attention will be given when the density of the current gas mixture reaches 6.0 grams per liter. Upon reaching 6.5 grams per liter, a warning will be given. The checks can be enabled or disabled via the menu CCR/pSCR setup > more. - Incremented upper limit for SAC Work to 80 l/min to ease usage of the OSTC gas needs calculation in Rock-Bottom mode. - Faster response to button events while in dive mode. - Hardened all USB/Bluetooth communication against data losses and timeouts. - Fixed Bluetooth item disappearing from menu. - A new Firmware Recovery Feature has been added: the currently active firmware can be backed-up and restored later on while other firmwares have been loaded thereafter. The feature is accessible via Settings -> System Settings -> Reset Menu -> Reboot and becomes available with the first firmware load after the V3.09 beta 4 (or later) is already on the unit. Change Note hwos Firmware 3.09.2 + 3.09.3 ========================================= - Added a function to acknowledge pending alarms, attentions and advices so that the exclamation-mark sign disappears: after pressing the left button until "Ackn?" appears, a press on the right button acknowledges the current alarm, attention or advice and suppresses the related sign. - Bugfixes: NDL not shown in big layout, external sensor not selectable, flash-write operation on some OSTC hardware, graphical garbage in depth output in big layout when deeper than 100 m. Change Note hwos Firmware 3.09.1 ================================ - Removed option 'ascent speed', ascent calculation is done with a fixed speed of 10 meters/minute now (equals the ascent speed limit by Bühlmann). - Improved calculation accuracy of the initial ascent. Remark: this will have a slight impact on the resulting deco schedule compared to firmware 3.07. - The deco calculator now figures in the salinity setting. - Aligned logbook and last dive summery of avg and max depth regarding rounding and incorporation of salinity setting. - Done some fine-tuning of depth outputs when using imperial units (feet). - In dive mode, sometimes the temperature was not shown any more after a gas change - fixed now. - The menu system around setting up the dive mode & settings has been decluttered. All settings are now sorted into the groups dive setup, deco setup, SAC (gas needs) setup, ppO2 setup and stops & depths setup. - There is a new option "Swap on empty" in Dive Setup -> SAC Setup. It is only effective if "CalcGas(B/O)" is switched on, too. If both options are switched on, the deco calculation will switch to another tank (i.e. gas) once the tank of the current gas is calculated to be used up. This function can be used to automatically calculate a contingency in case of running out of a deco gas, as the deco calculation will then continue to calculate a deco making use of the spares from the another gases carried. Another application is with two or more tanks holding the same gas (i.e. independent double configuration, side-mount), as the calculations will then take the cumulative amount of gas carried into account before raising a gas needs attention or alarm. - Fixed the urge of the better gas hint to always favor one specific gas out of a set of two or more gases that have the same change depth. - For dives done on firmware >= 3.09 the logbook will have one more page showing the tissue pressures and supersaturation levels as of at the end of dive (i.e. when surfacing). - As long as a gas or diluent is currently selected as breathed, it can not be set into the lost state any more. - When changing the battery or doing a cold start, the current CNS value does not get lost any more. - During loading of a new firmware the clock will not loose time any more (on old firmware it became late by about 15 sec on each firmware update). - When run from a 3.6 V battery (either replaceable or built-in), the surface mode timeout is now extended to 4 minutes before going to sleep mode. If the OSTC is run from 1.5 V disposables, the timeout remains at the previous 90 seconds to save on battery runtime. - Internal improvement: the code for the internal storage system and for the communication system (firmware uploading, dive data downloading) has been re-factored to secure maintainability for the next years to come. - Internal improvement: the scheduler for the dive mode calculation plans (fTTS, bailout) has been completely rewritten for better maintainability.
