Nokia C300 User Guide
incorporate substantial safety margins that are intended to assure the protection of all
persons regardless of age and health. The exposure guidelines are based on the Specific
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.
HAC notice
Your phone is compliant with the FCC Hearing Aid Compatibility requirements. The FCC has
adopted HAC rules for digital wireless phones. These rules require certain phone to be tested
and rated under the American National Standard Institute (ANSI) C63.19-2011 hearing aid
compatibility standards. The ANSI standard for hearing aid compatibility contains two types
of ratings: M-Ratings: Rating for less radio frequency interference to enable acoustic coupling
with hearing aids. T-Ratings: Rating for inductive coupling with hearing aids in telecoil mode.
Not all phones have been rated, a phone is considered hearing aid compatible under FCC
rules if it is rated M3 or M4 for acoustic coupling and T3 or T4 for inductive coupling. These
ratings are given on a scale from one to four, where four is the most compatible. Your phone
meets the M3/T3 level rating. However, hearing aid compatibility ratings don’t guarantee
