FCC Statement
1. 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.
(2) This device must accept any interference received, including interference
that may cause undesired operation.
2. Changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
NOTE:
This equipment has be en tes ted and fou nd to comply w ith t he 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 Information Statement
Your wireless phone is a radio transmitter and receiver. It is designed and
manufactured not t o ex c eed t he emission limits for exposure to radiofr eq uency
(RF) energy set by the Federal Communications Commission of the U.S.
Government. 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 throug h per iodi c and thor o ug h evaluation of scientific studies.
The standards include a substantial safety margin designed to assure the
safety of all persons, regardless of age and health. 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 1.6 W/kg. * Tests for
SAR are conducted with the phone transmitting at its highest certified power
level in all tested frequency bands. Although the SAR is determined at the
highest certifie d p ower level, the ac tu al S AR l evel of the phone w hil e 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 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 phone model is available for
sale to the public, it must be tested and certified to the FCC 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., at the ear
Page 9
and worn on the body) as requir ed by the FCC for each m odel . and when wor n
on the body, as described in this user guide, is 1.234W/Kg(Body-worn
measurements differ among phone models, depending up on 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 for safe exposure. The FCC has granted an
Equipment Authorization for this model phone with all reported SAR levels
evaluated as in compliance with the FCC RFexposure guidelines. SAR
information on this model phone is on file with the FCC and can be found
under the Display G r a nt s ecti o n of http://www .fcc. g ov/ oet/fccid after s ear chi ng
on
FCC ID: ZKQ-PLWAdditional information on Specific Absorption Rates (SAR)
can be found on the Cell ular Telec ommu nica tions Indus try Asso-ciation (CTIA)
web-site at http://www.wow-com.com. * In the United States and Canada, the
SAR limit for mobile phones used by the publi c is 1.6 w atts/kg ( W/kg) averaged
over one gram of tissue. The standard incorporates a sub-stantial margin of
safety to give additional protection for the public and to account for any
variations in measurements.
Body-worn Operation
This device was tested for typical body-worn operations. To comply with RF
exposure requirements, a minimum separation distance of 5mm must be
maintained between the user’s body and the handset, including the antenna.
Third-party belt-clips, holsters, and similar accessories used by this device
should not contain any metallic components. Body-worn accessories that do
not meet these requirements may not comply with RF exposure requirements
and should be avoided. Use only the supplied or an approved antenna.
