The ‘Usage Precautions’ for our wireless devices are there, buried in the owner’s manual. In print and/or in the settings/about area on your phone, you will find the info below in the fine print. When you hear about the ‘studies’ that show no effect, these studies are classifying cell phone users as people who use their phones 24 minutes A WEEK, and use them at least an inch away from the head… This is not how you see them advertised. in fact they are marketed as safe to put in our pockets, in our bras, or on our laps. it’s a reason it is there, to limit liability. This is why we all must know about this and teach our children how to use cell phones and laptop/tablets safely.
