The SAR value for FRITZ!Fon

When in use, cordless telephones emit electromagnetic radiation that heats up body tissues. The SAR value (SAR = specific absorption rate) indicates how much radiation the human body absorbs in W/kg (Watt per kilogram).

Like the majority of other DECT equipment manufacturers, we do not indicate the SAR value for this device class since the SAR value for cordless telephones is below 0.1 W/kg. The applicable SAR limit is 2 W/kg.

Cordless telephones only transmit when a call is in progress. The maximum permissible transmitter power is 250 mW per pulse. Due to the timeslot procedure used, this results in an average power output of no more than 10 mW while conducting a call. This means that according to EN 50360, the manufacturer is not required to determine and indicate the SAR value to prove compliance with legal limits, as is normally the case with mobile telephones.
