Sept. 10, 2003 FCC ID# H8NWLL220CL Applicant: Askey Computer Corp. Correspondence Reference Number: 25290 731 Confirmation Number: EA 185640 A3) Details of power measurement made for SAR. Are these peak or average? What is BW of measurement equipment? Response: There is a typo in the caption of Table 1on p. 12 of the SAR report . The caption should read " Peak conducted RF power" rather than Average conducted RF power. The procedure for conducted output power measurements used the channel power function of the Spectrum Analyzer Model FSEK 30. Attach an appendix giving the power outputs for various channels. 1

Appendix 1. PEAK TRANSMIT POWER MEASUREMENT 2. LIMITS OF PEAK TRANSMIT POWER MEASUREMENT Frequency Band Limit 5.15 – 5.25 GHz The lesser of 50mW (17dBm) or 4dBm + 10logB 5.25 – 5.35 GHz The lesser of 250mW (24dBm) or 11dBm + 10logB 5.725 – 5.825 GHz The lesser of 1W (30dBm) or 17dBm + 10logB Note: Where B is the 26dB emission bandwidth in MHz. 3. TEST INSTRUMENTS Description & Manufacturer Model No. Serial No. Calibrated Until SPECTRUM ANALYZER FSEK30 100049 July 24, 2003 NOTE: The calibration interval of the above test instruments is 12 months and the calibrations are traceable to NML/ROC and NIST/USA. 2

4. TEST PROCEDURE 1. The transmitter output was connected to the spectrum analyzer. 2. Set span to encompass the entire emission bandwidth of the signal. 3. Set RBW to 1MHz, VBW to 300kHz. 4. Using the spectrum analyzer’s channel power measurement function to measure the output power. 5. DEVIATION FROM TEST STANDARD No deviation 6. TEST SETUP EUT SPECTRUM 7. EUT OPERATING CONDITIONS The software provided by client to enable the EUT under transmission condition continuously at specific channel frequencies individually. 3
