This device 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.
SAR tests are conducted using standard operating positions accepted by the FCC with the
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 phone
while operating can be well below the maximum value. Before a new model phone is a
available for sale to the public, it must be tested and certified to the FCC that it does not
23
exceed the exposure limit established by the FCC, tests for each phone are performed in
positions and locations as required by the FCC. For body worn operation, this model phone
has been tested and meets the FCC RF exposure guidelines when used with an accessory
designated for this product or when used with an accessory that contains no metal.
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 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 into 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.
SAR tests are conducted using standard operating positions accepted by the FCC with the
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 phone
while operating can be well below the maximum value, in general, the closer you are to a
wireless base station antenna, the lower the power output.
Before a new model phone is a available for sale to the public, it must be tested and certified to
the FCC that it does not exceed the exposure limit established by the FCC, Tests for each

guidelines when used with an accessory designated for this product or when used with an accessory
that Contains no metal and that positions the handset a minimum of 10 mm from the body.
Non-compliance with the above restrictions may result in violation of RF exposure guidelines.
The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue.
Device types U400 (FCC ID: N2GU400) has also been tested against this SAR limit. The highest
reported SAR values for head, body-worn accessory, and product specific (Hotspot) are 0.72 W/kg,
0.81 W/kg, and 0.85 W/kg respectively. The Max simultaneous SAR is 0.98 W/kg.
