Hi Guys,

My EMF 390 meter measures 50-70 v/m2 around my Mac Book Pro. This comes from the ethernet cable. Wifi disconnected. Bluetooth as well. When I disconnect the cable, the EF is 10 v/m2 around my computer.

Some how, this doesn't seem right. Because cable should be safer... But the EF is too high.

It's connected via a USB-C converter with the keyboard and power connected to it. When I measure the ethernet cable alone (disconnected) it also is 50-70v/m2.

Any clues on how to bring down the V/m2?
The Router is probably the cause of the high voltage. It's Experia Box v8.

Kind regards!

Hi Rob,
The measured EF is just static EF. It might have come from the router connected through the ethernet cable. It just means that the outlet that the router/modem is connected to is also have that much EF and just pass it through the router. It might cause by some grounding issues. Dont need to worry about static EF as that level is harmless.
