the Xed-out garbage can sticker
 

Recently, on several electronic devices and components, I have seen a sticker with an Xed-out garbage can. Is it a reminder to recycle the item rather than throw it away? I can't guess what else it would mean.

I would imagine that you are not supposed to throw it away. Check where your nearest recycling center is and ask them if they take old electronics. In short, yea, any kind of electronics you are not supposed to simply throw away, it must be properly disposed of, like batteries and chemicals, etc.
