Health and safety
The device meets international guidelines for exposure to radio waves. Your device is a radio transmitter and receiver. It’s designed not to exceed the limits for exposure to radio waves recommended by international guidelines.
The guidelines were developed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), an independent technical standards body, and include margins designed to assure the safety of all persons, regardless of age and health. These guidelines use a unit of measurement known as Specific Absorption Rate (SAR). The SAR limit for the Bluetooth earbuds is 4.0 W/kg and the highest SAR value for this device when tested for use at the limb was 0.10 W/kg.
The SAR limit for the Bluetooth earbuds is 2.0 W/kg and the highest SAR value for this device when tested for use on the body was 0.10 W/kg 1. In SAR measurement, the separation distance between the Bluetooth earbuds device and the test device is 5mm.
As SAR is measured when the device is on its highest transmitting power, the actual SAR of this device while operating normally is typically below the levels shown above. This is because the device automatically changes its power level to ensure it only uses the minimum level required to reach the network. The World Health Organization has stated that present scientific information does not indicate the need for any special precautions for the use of mobile devices.
