FCC ID: POQWCE-210 FCC Part 22 Certification Gentlemen: On behalf of Withus IT Co., Ltd. is an application for Part 22 Certification of WCE-210 Dual-Mode Cellular Handset (AMPS/CDMA) as follows: FCC ID: POQWCE-210 Model: WCE-210 Equipment Class: Licensed Non-Broadcast Transmitter Held to Ear (TNE) Equipment Type: Dual-Mode Cellular Handset (AMPS/CDMA) Tx Freq. Range: 824.04 - 848.97 MHz (AMPS) 824.70 - 848.31 MHz (CDMA) Max. RF Conducted Power: 26.1 dBm (AMPS) 25.1 dBm (CDMA) Max. RF Output Power: 0.333 Watts ERP (AMPS) 0.265 Watts ERP (CDMA) Emission Designator(s): 40K0F8W, 40K0F1D, 1M25F9W Attached is the Authorization Letter, Confidentiality Request, ESN Affidavit, E911 Compliance Statement, Part 22 measurement report test data and photographs, RF exposure SAR measurement report test data and photographs, FCC ID label and location, internal and external photographs, block diagrams (confidential), circuit diagrams (confidential), circuit description (confidential), parts list (confidential), tune-up procedure (confidential), antenna specifications (confidential), operational description (confidential), and the user's manual with RF exposure warning statement.

FCC ID: POQWCE-210 Dear Martin: On behalf of Withus IT Co., Ltd., we hereby submit our response to the set-aside letter dated April 08, 2002 from Mr. Kenneth Nichols of the Commission, requesting additional information for the subject application. EMC: 1. Attached are the remeasured band edge plots showing compliance with the band edge requirements for CDMA mode. 2. Using a spectrum analyzer with video and resolution bandwidths of 3MHz to measure a CDMA signal gives inaccurate conducted RF power level measurements. The conducted RF power level of the CDMA signal was measured with an RF power meter operating in Modulated Average Power (MAP) mode. The conducted RF power level was set to 25.1dBm. Attached is a plot of the CDMA signal, set to 25.1dBm using MAPs mode, and displayed on a spectrum analyzer using a 3MHz resolution. The spectrum analyzer shows the conducted RF power level to be approximately 2.5dB greater than the actual. Also attached are revised CDMA bandwidth plots using only 30kHz video and resolution bandwidths. SAR: 1. The 835MHz probe conversion factors used for the SAR evaluation were 6.91 for head and 6.70 for body. The manufacturer’s specified probe conversion factors for 900MHz are 6.83 for head and 6.61 for body. An evaluation of the highest SAR values for the EUT using 900MHz probe conversion factors increased the overall SAR by approximately 3.4% for the head and approximately 1.5% for the body, which is less than the uncertainty of the probe conversion factors and considerably less then the overall uncertainty of the entire system. If you have any questions or comments concerning the above, please do not hesitate to contact me. Sincerely, Shawn McMillen General Manager Celltech Research Inc.
