18 BlackBerry Wireless Handheld
Important safety information
operating positions with the handheld transmitting at its highest
certified power level, the actual SAR level of the handheld while
operating can be well below the maximum value. This is because the
handheld 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.
Before a wireless handheld model is available for sale to the public,
it must be tested and certified to the FCC/IC that it does not exceed
the limit established by the government-adopted requirement for
safe exposure. The tests are performed in positions and locations
(e.g., worn on the body) as required by the FCC/IC for each model.
The highest SAR value for this model handheld when tested for use
when worn on the body, as described in this user guide, is 0.37
W/kg. (Body-worn measurements differ among wireless handheld
and phone models, depending upon available accessories and
FCC/IC requirements). While there may be differences between the
SAR levels of various wireless devices and at various positions, they
all meet the government requirement for safe exposure.
* In Europe, the SAR limit for mobile handhelds used by the public
is 2.0 Watts/kg (W/kg) averaged over 10 grams of tissue for the body
or head (4.0 W/kg averaged over 10 grams of tissue for the
extremities - hands, wrists, ankles and feet). The standard
incorporates a substantial margin of safety to give additional
protection for the public and to account for any variations in
measurements.
ANTENNA CARE
Use only the supplied integral antenna. Unauthorized antenna
modifications or attachments could damage the handheld and may
violate applicable laws and regulations by causing radio frequency
(RF) energy to be above the recommended limits. Any such
unauthorized use, modification or attachment will invalidate the
warranty provided with the handheld and may be dangerous.
