Poseidon have today released a new firmware upgrade to the Poseidon MKVI. This version is named 46P2 as it's the second patch of firmware version 46.
This patch has improved sensor monitoring and PO2 control and we recommend everyone diving the MKVI to download and install this firmware.
When diving the MKVI in waters with temperatures of 10°C (50F) and lower, we recommend that the diver do the following:
* Download and install firmware patch V46P2.
* Start the unit at the dive site to reduce the temperature difference between the O2 cell calibration (during the Pre Dive) and the O2 cell validation (during the dive).
* Do not use the top sponge. Only use the bottom sponge.
* If you doing more than one dive, ventilate the O2 cells between the dives.
