If you stick a piece of dynamite in the scanner and light it and it blows up it voids the warranty but no one was talking about that.
You did miss some things.
Several people said modifying or even opening the scanner would void the warranty.
A person posted numerous links with proof that opening, repairing, or modifying the scanner would not void the warranty, that it is illegal for manufacturers to say it would, and that the FTC has sent out warning letters to several companies telling them their warranty policies are illegal.
Several people were embarrassed to be proven wrong so instead of being thankful for being enlightened with the correct information which could be helpful to them, they stated bringing up other things that were never said and trying to make it look like they were right but failing miserably in the process.
Someone said soldering a grounding strap or the mitigation part to essentially eliminate the hum would deteriorate the specs and increase spurious emmissions under FCC Part 15.
Someone posted that the above was more inaccurate information.
That should do it.
I'm beginning to understand now Johnny Cochran . You're still wrong but won't fall on the sword. Good luck on your FTC complaint, if you're ever allowed to purchase one. But...don't tell people they won't void their warranty IF their unauthorized modification is determined to have caused damage to any product.
