Frequency RF exposure and SAR Your wireless modem device is a low power radio transmitter and receiver transceiver When it is turned on it emits low levels of radio frequency energy also known as radio waves or radio frequency fields Governments around the world have adopted comprehensive international safety guidelines developed by scientific organizations e g ICNIRP International Commission on Non Ionizing Radiation Protection and IEEE The Institute of Electrical and Electronics Engineers Inc through periodic and thorough evaluation of scientific studies These guidelines establish permitted levels of radio wave exposure for the general population The levels include a safety margin designed to assure the safety of all persons regardless of age and health and to account for any variations in measurements Specific Absorption Rate SAR is the unit of measurement for the amount of radio frequency energy absorbed by the body when using a transceiver The SAR value is determined at the highest certified power level in laboratory conditions but the actual SAR level of the transceiver while operating can be well below this value This is because the transceiver is designed to use the minimum power required to reach the network The MTX 631 65I wireless modem device has been approved for applications where the antenna is located gt 20cm from the body In all other configurations the integrator is responsible for meeting the local SAR
