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.
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.
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.
With erupting concern over police brutality, law enforcement agencies are turning to body-worn cameras to collect evidence and protect police and suspects. But how do they work? And are they even really effective?
A half century ago, cars were still built by people, not robots. Even on some of the country’s longest assembly lines, human workers installed windows, doors, hoods, engines, windshields, and batteries, with no robotic aid.
DuPont's Hytrel elastomer long used in automotive applications has been used to improve the way marine mooring lines are connected to things like fish farms, oil & gas installations, buoys, and wave energy devices. The new bellow design of the Dynamic Tethers wave protection system acts like a shock absorber, reducing peak loads as much as 70%.
