It is designed not to exceed the limitsfor exposure to radio waves (radio frequency electromagnetic fields), recommended byinternational guidelines from the independent scientific organisation, ICNIRP. These guidelinesincorporate substantial safety margins that are intended to assure the protection of allpersons regardless of age and health. The exposure guidelines are based on the SpecificAbsorption Rate (SAR), which is an expression of the amount of radio frequency (RF) powerdeposited in the head or body when the device is transmitting. The ICNIRP SAR limit for mobiledevices is 2.0 W/kg averaged over 10 grams of tissue.SAR tests are carried out with the device in standard operating positions, transmitting at itshighest certified power level, in all its frequency bands.Please refer to www.nokia.com/phones/sar for the maximum SAR value of the device.This device meets RF exposure guidelines when used against the head or when positioned atleast ⅝ inches (1.5 centimetres) away from the body. When a carry case, belt clip, or otherform of device holder is used for body-worn operation, it should not contain metal and shouldprovide at least the above stated separation distance from the body.To send data or messages, a good connection to the network is needed. Sending may bedelayed until such a connection is available. Follow the separation distance instructions untilthe sending is finished.© 2019 HMD Global Oy. All rights reserved. 35
