This is a perfect case of required warnings being used no matter if the person is an end user or repairer. < snipped material > > Never underestimate the stupidity of people challenged by > some intriguing label or instruction!

Seems he decided to look down the fiber to check if the laser was on. It was an IR device (invisible to the naked eye) and running at about 15mW. When I was asked about it by marketing, I said, "make sure to tell the "technician" not to look at the laser with his remaining good eye ... " Luckily, the guy wasn't harmed, but they got the point. Unintended consequences abound, but it is not our responsibility to design simple common sense into everything that's made. It's our responsibility for due diligence, good engineering practices, safety, etc ... But if the product is being sold to the general public, remember the customer base can have as much as -2 full deviations (that's minus two) from the mean IQ of the population. - Doug McKean ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
