FCC Compliance

This mobile phone complies with part 15 of the FCC Rules. Operation is subject to the following two
•
conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause undesired
operation.
This device 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 equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.
The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any
•
other antenna or transmitter.

Radio Frequency (RF) Energy

This device meets the government's requirements for exposure to radio waves.
This phone is designed and manufactured not to exceed the emission limits for exposure to radio
frequency (RF) energy set by the Federal Communications Commission of the U.S. Government.
The exposure standard for wireless device employs a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg. Tests for SAR are conducted using
standard operating positions accepted by the FCC with the device 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 phone while operating can be well below the maximum value. This is
because the device is designed to operate at multiple power levels so as to use only the poser required to
reach the network. In general, the closer you are to a wireless base station antenna, the lower the power
output.
The highest SAR value for the device as reported to the FCC when tested for head, as described in this
user guide, is 1.00W/kg for UMTS band II.
While there may be differences between the SAR levels of various phones and at various positions, they
all meet the government requirement.
