      In addition, whether wireless signal is harmful to the human body concerned only with the transmitter power and not related with frequency and modulation（FM\AM）.Transmitter  power of call button is nearly 10MW , not more than one-tenth  launched radiation human impact of GSM and CDMA mobile phone even full power of wireless call button .

      Studies have shown that any electronic product in work states, inevitably there are electromagnetic radiation, electromagnetic radiation wireless call button is very weak.World health organization declared high frequency fields generated by mobile phones do not cause cancer, so much smaller than the cell phone wireless calling system will not cause disease and lesions.
