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 mobile phone 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.
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.
RF Exposure
Information (SAR)
This mobile phone 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 mobile phones 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 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.
This is because the phone 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 model phone as reported
to the FCC when tested for use at the ear is 0.227 W/kg
and when worn on the body, as described in this user
guide, is 1.248W/kg (Body-worn measurements differ
among phone models, depending upon available accessories
and FCC requirements.) While there may be differences
between the SAR levels of various phones and at various
positions, they all meet the government requirement.
The FCC has granted an Equipment Authorization for this
model phone with all reported SAR levels evaluated as in
compliance with the FCC RF exposure guidelines.
Simultaneous RF exposure is 1.412W/Kg.
SAR information on this model phone is on file with the FCC
and can be found under the Display Grant section
www.fcc.gov/oet/ea/fccid after searching - FCC ID:
2AFJ5K5
For body worn operation, this phone has been tested and
meets the FCC RF exposure guidelines for use with an
accessory that contains no metal and the positions the
handset a minimum of 1.0cm from the body. Use of other
accessories may not ensure compliance with FCC RF
exposure guidelines. If you do not use a body-worn accessory
and are not holding the phone at the ear, position the
handset a minimum of 1.0 cm from your body when the
phone is switched on.
