radio-frequency (RF) energy. These limits are part of comprehensive
guidelines and establish permitted levels of RF energy for the
general population. The guidelines are based on standards that were
developed by independent scientific organizations through periodic
and thorough evaluation of scientific studies. These guidelines include
a substantial safety margin designed to ensure the safety of all
persons, regardless of age and health.
The exposure standard for mobile phones employs a unit of
measurement known as the Specific Absorption Rate, or SAR.
The SAR limit set by public authorities such as the Federal
Communications Commission of the US Government (FCC), or by
Industry Canada, is 1.6 W/kg averaged over 1 gram of body tissue.
Tests for SAR are conducted using standard operating positions with
the mobile phone transmitting at its highest certified power level in
all tested frequency bands.
Although the SAR is determined at the highest certified power level, the
actual SAR level of the mobile phone while operating can be well below
the maximum value. This is because the mobile phone is designed to
operate at multiple power levels so as to use only the power required
to reach the network. In general, the closer you are to a wireless base
station antenna, the lower the power output of the mobile phone.
Before a mobile phone model is available for sale to the public,
compliance with national regulations and standards must be shown.
The highest SAR value for this model mobile phone when Tested is
0.190 W/kg for use at the ear and 1.56W/kg for use close to the body.
While there may be differences between the SAR levels of
various mobile phones and at various positions, they all meet
the government requirement for RF exposure. For body-worn
operation, the mobile phone meets FCC RF exposure guidelines
provided that it is used with a non-metallic accessory with the
handset at least 10 mm from the body. Use of other accessories
may not ensure compliance with FCC RF exposure guidelines.
Additional information on SAR can be found on the Cellular
Telecommunications & Internet Association (CTIA) Web site: http://

The World Health Organization (WHO) considers that present
scientific information does not indicate the need for any special
precautions for use of mobile phones. If individuals are concerned,
they might choose to limit their own or their children's RF exposure
by limiting the length of calls, or using "hands-free" devices to keep
mobile phones away from the head and body. (fact sheet n°193).

Note: This equipment has been tested and found to comply with the
limits for a Class B digital device pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
