FCC ID: KA2WA123A1 Report No.: SE990727E02A Declaration Letter Bureau Veritas Consumer Products Services (H.K.) Ltd., Taoyuan Branch January 6, 2011 Dear Application Examiner, Per the request from our client that the Average power is considering a confidential info for their product at this stage and they don’t want this info been shown in the SAR report. The removal of average power value from the SAR report doesn’t affect the validity of the report, since all modulations have been tested and average power was not used in the test report for justifying the test reduction. Accordingly, we would like original SAR report be superseded with the new attached version. Thanks. Please contact me if you have any further questions. Thanks for your attention.
