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. FCC ID: 2AH25W6900 NOTE: Changes or modications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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 o 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 dierent from that to which the receiver is connected.

---Consult the dealer or an experienced radio/TV technician for help. Body-worn Operation This device was tested for typical body-worn operations. To comply With RF exposure requirements, a minimum separation distance of 1.0cm must be maintained between the users body and the handset, including the antenna. Third-party belt-clips, holsters, and similar 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. Specic Absorption Rate (SAR) information:

This wireless phone meets the government's requirements for exposure to radio waves. The guidelines are based on standards that were developed by independent scientic organizations through periodic and thorough evaluation of scientic studies. The standards include a substantial safety margin designed to assure the safety of all persons regardless of age or health. FCC RF Exposure Information and Statement. The SAR limit of USA

(FCC) is 1.6W/kg averaged over one gram of tissue. Device types: W6900 has also been tested against this SAR limit. The highest SAR value reported under this standard during product certica-

tion when properly worn on the body is 1.856W/kg10gSAR test distance0mmlimit 4W/kgand 1.477W/kg (1gSAR test distance 5mmlimit 1.6W/kg). This device was tested for body-worn operations with the back of the handset kept 0mm and 5mm from the body. To maintain compliance with FCC RF exposure requirements, use accessories that maintain a 0mm and 5mm separation distance between the user's body and the back of the handset. The use of belt clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided.

(Print name) 1 - The asterisked items (*) require further justification before permanent confidentiality will be allowed. These also currently require review by the FCC under their Permit-But-Ask policy before the grant is issued and can delay completion of an application. Further justification should be added to the note above. One such example for a potted device would be: The EUT is FULLY potted using a non-removable epoxy based material. Removal of potting material causes irreparable damage to internal circuitry. See photographs exhibits that outline the device before and after potting. 2 - Please refer to http://acbcert.com/documents/misc-docs/Memo-Short-Term-Vs-Standard-Confidentiality.pdf for complete details. 3 - Must be signed by applicant contact given for applicant on the FCC site, or by the authorized agent if an appropriate uthorized agent letter has been provided.
