There is problem in the Cobalt date checking routine that prevented firmware versions 1.10 and later from automatically updating the year to 2012. Please check your Cobalt's date. If it is incorrect, change the year in the "Set Time and Date" screen to 2012, so your dive log will record new dives with the actual date. If left in year 2011 and there is an existing dive in the log just previous to the new dive, you might experience shorter than normal no-deco times as the Cobalt will treat it as a repetitive dive. Do not attempt to change the date if you are between dives. Always wait at least 24 hours after your last dive before changing the date or time or you will lose the repetitive dive calculation. This will be corrected in the next firmware release.
In the event you are unable to complete the date change to 2012 please contact Atomic at (714) 375-1433 or take it to your local Authorized Atomic Retailer.
