YES IT IS

IT IS OFF TOPIC BECAUSE MATT POSTED A PROBLEM HE IS HAVING AND ASKED RBW MEMBERS IF THEY HAD EXPERIENCED THE SAME OR SIMILIAR PROBLEMS AND ANY SUGGESTIONS ON CAUSE OR HOW TO FIX. INSTEAD OF ANSWERING THE QUESTION YOU POSTED AN ASSUMTION THAT HIS ELECTRONICS ARE OF SUB-STANDERED QUALITY, HOW FOOLISH YOU THINK HE AND EVERYONE ELSE IS AND HOW EVERYONE ELSE BUT YOU HAS SUB-STANDERDS. TELL ME KARL NOT COUNTING BENCH HOURS HOW MANY CCR IN WATER HOURS DO YOU HAVE, PLEASE GIVE BREAK DOWN ON WHICH UNITS AND DEPTHS? OH AND PLEASE IF I MAY BE SO BOLD TO ASK, "WHAT MAKES YOU SUCH A CCR ELECTRONICS AUTHORITARIAN?

Stuart, Matt and RBW sorry for the hijack and rant. (please start a new thread Karl Denninger "The CCR Electronics Authoritarian")

Thank you as I felt I was the only one who thought this way. Have some green. Again sorry for being off topic.

The answer was given multiple times - the unit is not working correctly, send it back.

Then the OP posted an opinion from the factory that it was considered "normal" for it to freak out like this if it powered up "funny."

So now it appears that the OP still has the head and is not going to send it back for service. I believe that's dangerous since he still doesn't know what's going on with it, and IF the factory's position is that power-up glitches like this are "normal" then I stand by my comment about that being ridiculous. You wouldn't tolerate that sort of behavior in your microwave oven or DVD player - but its ok in your life support gear?!

20+ years of designing and building human-life-safety critical micro-controllers for various industrial purposes, encompassing both hardware and software, dating back to the original release of the Z80 microprocessor, likely puts me in the position of being qualified to express an opinion about similar electronic devices.

I said my peace and was done with it, but since screaming in all caps and questioning my qualifications to express an opinion on safety-critical electronics became reasonable it is only appropriate to put that issue to rest.

The OP's unit is broken and needs to be fixed. Whether that's a design problem or a unit-specific issue (e.g. water intrusion) is not the point - that it is IMHO demonstrably unsafe in its current condition is.

I would not dive it and strongly suggest that the OP doesn't either until the source of the issue is identified, communicated to him, and resolved, including powering up properly 100% of the time.

My motivation in posting on this thread is simply that I don't want to read about any more fatalities.

Flame on folks - I've said my peace and discharged my ethical responsibility to help prevent people from getting needlessly killed.

OK folks. We seem to have started diluting far too many threads by going off topic.

Karls been asked to play his part in this, by starting new threads when he feels the need to leave the original topic. It'd be good if everyone could do the same.

Lets try and get RBW back to being a useful information source, rather than serving as an online dick size competition (which for the record I win, smallest always wins, right?). If people cant do that, Im afraid we may have to moderate a bit more than we want to for a while.

Thanks.

Hey, if it weren't for Karl all you mods would have a very dull time

Irritating and entertaining in equal parts?

I think he just wants some attention

I wouldn't think equal, more like 90 and 10 percent...

***EBT*** · 15th December 2006, 16:35

Cmon lads... thread drift?

Hope 3 winks don't constitute a thread drift?

No, but they do make me nervous. Are you Charlene at the weekend?

sounds like moisture is the main issue from the responses here, but i figure i'd throw in a thought that will hopefully be helpful and not crossing bounds here. Because decay characteristics of batteries differs widely from brand to brand, and seems to really make a difference in the vision electronics, is there a particular brand of battery that the voltage regulation system on the meg likes the best that would help someone in mat's position rule out battery issues?

more and more in my life, weather it is with my car and a battery that seemed good, to a variety of other electronics, i'm comming to conclude that battery quality can make a surprising influence on their overall operating performance even if the battery reads ok.

just a thought
