Suunto D6 and D9 Dive Computers Recalled Due to Software Bug

Suunto Oy has identified a software bug in the D9 and D6 diving instruments. The software bug may cause the D9 and D6 to incorrectly track dive time on rare occasions, potentially causing a risk to the diver. For further information please read more here. Therefore, Suunto is requesting that the D9 and D6 products with the serial numbers listed below shall be returned for a software update that eliminates this issue.

The products affected are:

D9 serial numbers 62102582 and below
D6 serial numbers 62103693 and below

Suunto strongly recommends that D9 or D6 should not be used for diving before the unit has been updated with the latest software. If the product is used before updating the software, backup instrumentation must also be used.

Suunto will provide a free software update to fix the bug. Please bring your D9 and/or D6 to your nearest local authorized Suunto retailer for the software update as soon as possible. For contact information please visit our web site www.suunto.com If that is not possible or if you require any further details, contact the Suunto Help Desk at SuuntoD9-D6@nordictelecenter.fi To contact Suunto by phone, call toll free 1 800 543 9124 in the USA and Canada, or +358 284 1160 (international call rates are applicable) from all other countries.

As a complimentary service Suunto will at the same time replace your battery and perform a pressure test free of charge.

Suunto apologizes for any inconvenience.

Yeah, I have one of those D9's. When I called Suunto they said the fix would be in the US within a week. When I asked about what one does who is heading off for a couple of weeks diving before it could possibly be returned, the answer was basically, "bummer for you, dude. Call Aqualung since you bought it at a LDS." Did that; response was the same: "gotta suck bein you."

So I have bought a new computer.

Here is another article on this issue someone at work sent me. It goes into a bit more detail about the problem.

very interesting stuff in that article, RIO:

The software bug may activate when the D9 and D6 automatically recalibrate to keep the correct time, or the user manually updates the seconds in set mode. Suunto approximates that there is 0.6% (a six-tenths of one percent) chance that the software bug may appear during a dive. When the dive time is incorrect, every fourth second is not registered in the dive time and surface interval time, i.e., dive time goes 25% slower than actual time and tissue loadings are recorded at 25% less than actual loadings. As a trained diver you understand that this could affect your decompression requirements and that the length of a dive is one of the key factors in determining those requirements.

Even though the D9 and D6 will function correctly approximately 99.4% of the time during a dive, Suunto wants to eliminate the very small possibility of recording the dive time incorrectly. Therefore, Suunto is requesting that all D9 and D6 shall be returned for a software update that eliminates this issue. To date, there have been no known injuries related to this issue.
