Intimidation to Answers

How to get answers?  I was doing worst case design analysis and needed the substraight thermal resistance.  I would call and ask. Stone wall - no reply.  I would inflate the number required.  And said that if I don't get an answer I will have to find another device.  Quick finical calculations 10000 devices at $3 apiece.  I was actually designing for MX missile basing and there are just not that many silos.

It is in good course for the manufacturers to keep the secret codes to themselves but they should also consider the impact the move might impose on their customers. Some equipments can break down at the wee hours of the night and force someone to wait till dawn in order to get them repaired, am not disputing their reasoning but the odds are better with the codes out in the open.

I think the vast majority of readers on our website would agree with you, Kirk McLoren. Many people, and certainly most engineers, would prefer that manufacturers make their products so they can be repaired by the owners.

I suppose all that's so but these lads evidently couldn't properly fit a wire.

I am not sure that I like a manufacturer treating me as a mushroom. I usually repair my gear out of necessity. I want that option open.

Ah, that would make a difference, wouldn't it, Chuck. Not exactly the best view to have, but at least it makes them more responsive!

I believe that the auto industry views reporters as a free marketing arm, whereas these guys obviously don't.

You're so right, Chuck. I don't think they should just see it automatically as a negative and perhaps take the opportunity to educate people about their products..maybe people are using them incorrectly or are misinformed about features or technology. But not everyone sees it that way, obviously.

I have to say, Liz, that I am also baffled by the manufacturers' unwillingness to speak to the press. I'm more impressed if a manufacturer steps up to a forum like this one and says, Here's why we had (or didn't have) this problem."

There are a few reasons to keep the codes or "key dance" semi-secret.  This is
an Engineering message board, so the readers are more educated than the average
consumer.  If the average consumer had access to the service codes EEPROMs would
be erased, motors would be run through life tests, thermometers would be
recalibrated, dogs would be sleeping with cats.... total chaos.

Secret combo

I love it when they incorporate those secret combos into things. The only way to know them IS with a proper service manual, which or course only repair men have. I had a tv like that. It had issues so I called my tv repair buddy over. He hit the code..bam bam bam...it was fixed! They should include the codes with the unit, but I suppose if they did that you wouldn't: A: have to call a repair man or B: just buy a new one.
