DANGER vTo avoid electric shock hazard, connect and disconnect cables appropriately when installing, moving or opening the covers of this product or attached devices. Use the power cord with a properly grounded outlet. vDo not leave the base of your computer in contact with your lap or any part of your body for an extended period when the computer is functioning or when the battery is charging. Your computer dissipates some heat during normal operation. This heat is a function of the level of system activity and battery charge level. Extended contact with your body, even through clothing, could cause discomfort or, eventually, a skin burn. vTo reduce the risk of electric shock, do not use your computer in or near water. vTo avoid electric shock, do not use your computer with the telephone cable connection during an electrical storm. Do not connect the cable to or disconnect it from the telephone outlet on the wall during an electrical storm. vStore packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags. vThe battery pack contains a small amount of harmful substances. There is danger of an explosion if the battery pack is incorrectly replaced, exposed to fire or water, short-circuited or disassembled. Keep the battery pack away from children and do not put it in trash that is disposed of in landfills. vTo reduce the risk of fire, use only No. 26 AWG or thicker telephone cable. vThe fluorescent lamp in the LCD contains mercury. Do not put it in trash that is disposed of in landfills. Rough handling or dropping the computer can cause the LCD to break and the internal fluid to get into your eyes or on your hands. Immediately wash the affected areas with water. If symptoms persist, seek medical care. vDo not disassemble the optical storage drive unit, as this might result in hazardous radiation exposure. vAvoid direct eye exposure with the laser beam contained in some drives.

FCC ID: ANOCORN1TASUHOP Document Number: FCC-19-0182-0 1/9 IBM Japan Ltd. 1623-14, Shimotsuruma, Yamato-shi Kanagawa-ken 242-8502, Japan April 15, 2002 To whom this may concern OET Requested Information FCC ID : ANOCORN1TASUHOP Applicant : International Business Machines Corporation Correspondence Reference Number : 22603 731 Confirmation Number : EA935585 Original Requested Date : April 13, 2002 Subjects : EMC portion With regard to your new request to implement method for replacing a broken WLAN card by the user themselves. Subject 1) Please provide correspondence for the acceptance by FCC on February 2002 about your proposal. Answer 1) Please refer the Attechment-1 of this correspondence. Subject 2) Will this be only for broken WLAN cards and not for upgrade options? Answer 2) We plan to support only broken WLAN cards for the ANOCORN1TASUHOP. Subject 3) Will the (BIOS Lock) be used with other notebook computers? Subject 4) Will the WLAN card be used with other notebook computers? Answer 3/4) Yes, we plan to add other notebook computers with BIOS Lock mechanism, and will have the FCC authorizations for each PC model with different FCC IDs. Subject 5) If the WLAN card will be used with other computers, will a different output power be used? Will different antennas be used? How would you ensure that SAR compliance? Answer 5)- We have no plan to modify the applying WLAN card. i.e. The conducted output power must be the same. - Yes, different antennas will be used for other computers after being certified with different FCC IDs. - Usually the antennas of our products are located at the top of LCD panel, so they may be subjected to MPE. If we will have a different design (like a keyboard antenna), we will have the SAR testing in accordance with the latest FCC rule. note) We need to confirm the treatment for transmitters below 10mW whether it may be allowed MPE or not. Subject 6) Does the (BIOS Lock) check the proper antenna and card combination? Answer 6) The BIOS Lock checks the peculiar information of each authorized card, not checks any antenna info. Because the integrated antenna is (will be) unique for each PC model, so the BIOS does not need to detect the antenna type of its own host unit. Please refer the Attechment-2 adding more details of the BIOS Lock. FCC ID: ANOCORN1TASUHOP Document Number: FCC-19-0182-0 2/9 Subject 7) Does the (BIOS Lock) check the proper antenna and output power combination? Answer 7) The BIOS Lock dose not check output power, but checks the detail RF chipset info instead. IBM will not modify the power of authorized RF cards, so the function must be equal to the detection of the card manufacturing level. Also please refer the Attechment-2 adding more details of the BIOS Lock. Subject 8) The FCC identifier and label can only be placed on a complete transmitter. How is this ensured when the WLAN card is sold without the antenna? You'll be shipping/marketing incomplete transmitters. Subject 9) How does this proposal comply with 15.204 requirement that a complete system is marketed together? This replacement does not have an antenna. Answer 8/9) As for the ANOCORN1TASUHOP, the RF WLAN card will be delivered to the customers for replacing broken cards only, not marketed for sales independently. To allow customers to install the repair parts, we implement the BIOS Lock to guarantee the Part 15.203. When we will market the card as the IBM option, we will process the proper certification of LMA (by the card supplier) in line with the new rule of Attachment-1. Subject 10) Please provide any additional information to ensure that the system will comply with EMC and SAR requirements when any changes to antenna or output power is made. Will Class II permissive changes be filed for all notebooks using this system? Answer 10) Usually we have the FCC IDs for each system unit, not for card. So we measure all test items for each model even though a same card was used for several models. If antenna will be changed, we re-measure the Part 15.205/207/209(EMC) and do class II change. ANOCH126H8056 is the case of it. We don't modify the card, so we have no case of power change. As for SAR, we have used MPE, so we could proceed with only the calculation using the conducted power and antenna gain. The Class II change is very rare for us, because we take a system grant approach (not LMA). Almost submissions are done as original filings with different new FCC IDs. Subject : RF Safety portion Subject: FYI - in future filings please do not submit MPE "estimation" analyses for distances less than 20 cm. Answer: Thank you but we still need a confirmation whether the rule will be applied to a low power transmitter below 10mW (e.g. Bluetooth 3mW). Subject: Concerning revised RF exposure statement in users manual: there are typographical errors, and we have the following comments for your consideration only: Answer: Thank you very much. We will fully follow your advice, and would like to attach the update for the sure. Please see the Attachment-3. Sincerely, April 15, 2002 Toshiya Murota Staff Engineer, EMC Engineering Yamato Laboratory, IBM Japan Ltd. FCC ID: ANOCORN1TASUHOP Document Number: FCC-19-0182-0 3/9 Attachment-1: Response from the FCC on February/2002 "Rich Fabina" <[email protected]> 02/06/02 11:12 AM To: George Kavelak/Raleigh/IBM@IBMUS cc: Subject: Re: Awaiting Your Response George, Yes, we find the proposal attached acceptable. Sorry for not getting back to you sooner but things just keep getting busier and busier. Rich >>> "George Kavelak" <[email protected]> 02/04/02 12:40PM >>> Rich, at our meeting Friday, January 25, 2002 you indicated that you would try to get back with your answer by Friday February 1, 2002 on our proposal regarding a label on the bottom of the laptop near the Customer Access Panel for the Mini-PCI transmitter card (limited modular approval with an FCC ID on the card). The label would indicate that an FCC ID for an installed transmitter card is viewable un…

According to FCC regulations [1], a direct sequence spread spectrum system must have a processing gain, G p of at least 10 dB. Compliance to this requirement can be shown by demonstrating a relative bit-error-ratio (BER) performance improvement (and corresponding signal to noise ratio per symbol improvement of at least 10 dB) between the case where spread spectrum processes (coding, modulation) are engaged relative to the processes being bypassed. In some practical systems, the spread spectrum processing cannot simply be bypassed. In these cases, the processing gain can be indirectly measured by a jamming margin test [2]. In accordance with the new NPRM 99-231, if the vendor has a system with less than 10 chips per symbol, the CW jamming results must be supported by a theoretical explanation of the system processing gain. intersil PRISM radio Jamming Margin Test _________________________________________________________________________________________________________ _____________________________________________________________________________________ intersil Page 2 Theoretical calculations The processing gain is related to the jamming margin as follows [2]: system output p L S J N S G+       +       = Where BER REFERENCE is the reference bit error ratio with its corresponding, theoretical output signal to noise ratio per symbol, (S/N) output , (J/S) is the jamming margin (jamming signal power relative to desired signal power), and L system are the system implementation losses. The maximum allowed total system implementation loss is 2 dB. The ISL3874 direct sequence spread spectrum baseband processor uses CCK modulation which is a form of M-ary Orthogonal Keying. The BER performance curve is given by [5]: ì The probability of error for generalized M-ary Orthogonal signaling using coherent demodulation is given by: PPQz E z dz ec b M S N =− =−−+               −       − − ∞ ∫ 11 1 2 212 2 1 2 1 2 01 0 π η ()exp This integral cannot be solved in closed form, and numerical integration must be used.

The corresponding Es/No (signal to noise ratio per symbol) is 16.4 dB. The Es/No required to achieve the desired BER with maximum system implementation losses is 18.4 dB.

The corresponding symbol rates are 1, 1, 1.375, and 1.375 MSps. The chip rate is always 11 MCps, so the ratio of chip rate to symbol rate is 11:1 for the 1 and 2 Mbps rates and 8:1 for the 5.5 and 11 Mbps rates. Since the symbol rate to bit rate is less than 10 for the higher rates, we supply the theoretical processing gain calculation for these cases where both spread spectrum intersil PRISM radio Jamming Margin Test _________________________________________________________________________________________________________ _____________________________________________________________________________________ intersil Page 4 processing gain and coding gain are utilized. This is reasonable in that they cannot be separated in the demodulation process. If a separable FEC coding scheme were used, we would not be comfortable making this assertion.

FCC Test Report FCC ID: ANOCORN1TASUHOP Document Number: FCC 19-0182-0 Prepared by T. Murota 1/4 RF Exposure The applying equipment is a standard fullsize laptop computer which is categorized as a mobile device by FCC CFR 47 Section 2.1091. Therefore the separation distance between the antenna and the human body is 20cm or more. As shown in the following photos, the applying equipment satisfies the requirement of antenna separation. 1. IBM High Rate Wireless LAN Mini-PCI Adapter with Modem II The conducted peak output power of the IEEE802.11b Wireless LAN Adapter is 17.0dBm and the maximum antenna gain is 0.53dBi as shown below. Figure A: Antenna Gain of IEEE802.11b Wireless LAN Adapter The separation distance between the antenna and the human body is 20cm or longer. FCC Test Report FCC ID: ANOCORN1TASUHOP Document Number: FCC 19-0182-0 Prepared by T. Murota 2/4 Therefore the peak radiated output power(EIRP) is calculated as follows. EIRP = P + G = 17.0 dBm + 0.53 dBi = 17.53 dBm (56.6 mW) Then, the maximum power density at 20cm distance is calculated as : S 1 = EIRP/(4 % R 2 % o) = 0.0113 mW/cm 2 2. IBM Bluetooth Daughter Card The peak conducted output power of the Bluetooth Daughter Card is 3.9 dBm and the maximum antenna gain is 1.87dBi as shown in the Figure B. Therefore the peak radiated output power(EIRP) is calculated as follows. EIRP = P + G = 3.9 dBm + 1.87 dBi = 5.77 dBm (3.78 mW) Then, the maximum power density at 20cm distance is calculated as : S 2 = EIRP/(4 % R 2 % o) = 0.00075 mW/cm 2 The separation distance between the antenna and the human body is 20cm or longer.
