Body worn operation
The device complies with RF specifications when used near your ear or at a distance of 5mm from your body.
Ensure that the device accessories, such as a device case and device holster, are not composed of metal
components. Keep the device away from your body to meet the distance requirement.
Certification information (SAR)
This device meets guidelines for exposure to radio waves. Your device is a low-power radio transmitter and
receiver. As recommended by international guidelines, the device is designed not to exceed the limits for
exposure to radio waves. These guidelines were developed by the International Commission on Non-Ionizing
Radiation Protection (ICNIRP), an independent scientific organization, and include safety measures designed to
ensure the safety of all users, regardless of age and health.
The Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency energy
absorbed by the body when using a device. The SAR value is determined at the highest certified power level
in laboratory conditions, but the actual SAR level during operation can be well below the value. This is because
the device is designed to use the minimum power required to reach the network.
The SAR limit adopted by Europe is 2.0 W/kg averaged over 10 grams of tissue, and the highest SAR value for
this device complies with this limit.
The highest SAR value reported for this device type when tested at the ear is 0.961 W/kg, and when properly
worn on the body is 1.604 W/kg.
