Nokia C21 User Guide
Absorption Rate (SAR), which is an expression of the amount of radio frequency (RF) power
deposited in the head or body when the device is transmitting. The ICNIRP SAR limit for mobile
devices 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 its
highest certified power level, in all its frequency bands.
This device meets RF exposure guidelines when used against the head or when positioned
at least 5/8 inch (1.5 centimetres) away from the body. When a carry case, belt clip or other
form of device holder is used for body-worn operation, it should not contain metal and should
provide 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 be
delayed until such a connection is available. Follow the separation distance instructions until
the sending is finished.
During general use, the SAR values are usually well below the values stated above. This is
because, for purposes of system efficiency and to minimize interference on the network,
the operating power of your mobile device is automatically decreased when full power is not
needed for the call. The lower the power output, the lower the SAR value.
Device models may have different versions and more than one value. Component and design
changes may occur over time and some changes could affect SAR values.
For more info, go to www.sar-tick.com. Note that mobile devices may be transmitting even if
you are not making a voice call.
The World Health Organization (WHO) has stated that current scientific information does
not indicate the need for any special precautions when using mobile devices. If you are
interested in reducing your exposure, they recommend you limit your usage or use a hands-
free kit to keep the device away from your head and body. For more information and
explanations and discussions on RF exposure, go to the WHO website at www.who.int/health-
topics/electromagnetic-fields#tab=tab_1.
Please refer to www.nokia.com/phones/sar for the maximum SAR value of the device.
