Electromagnetic radiation (EMR) is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays, gamma rays and sunlight. Both cell phones and bluetooth receivers use microwave radiation to transmit and receive data. There is currently a healthy debate over the potential danger of both cell phone and bluetooth headset radiation, especially as they are both held directly to the head.

The difference between cell phones and bluetooth headsets is significant and can be seen in their emission power: cell phones emit signals which are picked up by a tower many miles away, while average Bluetooth technology transmits with enough power to maintain a connection only 10-50 feet from a wireless device.

Bluetooth headsets come in 3 levels of transmission power: Class I , Class II, and Class III. Class III is the least powerful and emit such a weak signal that they are not included in the general bluetooth/EMR debate. The Dreampad bluetooth receiver, having a reach of less than 33 feet, is a Class III transmitter. According to the experts, even if it were worn against the head it would not be considered potentially harmful.

Regarding EMR emissions from your cell phone when using it to play music for the Dreampad, we recommend putting your phone of Airplane Mode. In this mode, no signals are sent or received but you can still play music.  (Airplane Mode is also important because it prevents in-coming calls from waking you while you’re sleeping.)

We continue to monitor the debate over EMR risk and we welcome your questions and any new information you come across. Bottom line: we can’t be too safe.
