Exposure to radiofrequency radiation from DECT phones and other sources can have general metabolic effects see http://www.heartmdinstitute.com/v1/wireless-safety/cordless-phone-use-can-affect-heart for a brief video discussion. Affects on cardiac rhythm and function are being reported. Children are also affected, perhaps especially so. Visit http://www.safeschool.ca and http://www.magdahavas.com/?s=bradycardia for additional information about children, arrhythmias, and wireless technology. To read more about this and other symptoms of radio frequency sickness, please visit http://www.magdahavas.com or http://www.electricalpollution.com for more information.
If you have questions about whether your phone transmits even when hung up, use a meter with an appropriate frequency range to test it. You can also call the technical support line for the company with your model and serial numbers and ask them whether the phone transmits continuously or only during a phone call. Cordless phones that transmit continuously have been causing illness.

"BACKGROUND INFORMATION ON DECT PHONES
Please download and read the whole document. The findings, not surprisingly, show that people suffer from the symptoms of Radiofrequency Sickness when constantly exposed to high frequencies. The document contains information about the DECT technology and the effect it has on health. Please pass the document on to friends, relatives, public officials, doctors, and consumer protection advocates. This is important information for people to have as they make decisions about what risks they want to take and what technologies they want to use.
If, for some reason, you must have a cordless phone, phones that only transmit during the call can still be found - although almost exclusively at re-sale shops and garage sales. They are far and away the minority. If you want to get one new, the best step is to call the tech department at the company you wish to purchase your phone from and ask if they make a model that does not transmit when it is not in use. (Thus, you are only exposed to microwave transmissions when the phone is actually in use, not continuously.)
Caution: DECT phone base stations (transmitters) can have cords. All corded phones should be checked to be sure that they do not say DECT on them, if they do, remove them.
