 Note Before using this information and the product it supports, be sure to read the general information under Appendix A, “Important safety instructions” on page 39, Appendix B, “Wireless related information” on page 45, Appendix C, “Wireless regulatory notice” on page 47, Appendix D, “Warranty information” on page 53, and Appendix E, “Notices” on page 67. 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.

IBM Japan, Ltd. Document Number: FCC 19-0186-0 Prepared by T. Murota 1/1 RF Exposure Evaluation for IBM ThinkPad T30 Series As shown in the following photos, the transmission antenna position of IBM ThinkPad T30 Series is located at the top of its display (LCD) bezel. And the separation distance between the antenna and the human body is 20cm or more. Therefore the equipment can be categorized as a mobile device by FCC CFR 47 Section 2.1091. The highest conducted peak output power of the applying equipment (FCC ID : MCLU58H004) is 93.3mW(19.7dBm) and the maximum antenna gain is 0.53dBi. Therefore the peak radiated output power(EIRP) is calculated as follows. EIRP = P + G = 19.7 dBm + 0.53 dBi = 20.23 dBm (105.44 mW) Then, the maximum power density at 20cm distance is calculated as : S = EIRP/(4 % R 2 % o) = 0.021 mW/cm 2 When an operator will use the transmitter during 30 minutes continuously in normal operation, the time-averaging exposure is : S % 30 = 0.63 So the source-based time-averaging duty factor is considered as 100% duty. Therefore the applying equipment meets the MPE requirements for general Population/ Uncontrolled exposure. The separation distance between the antenna and the human body is 20cm or longer.

360 Herndon Parkway Suite 1400 Herndon, VA 20170 http://www.rheintech.com Certification Report For: Cisco System Page 36 Document Number: 2001041 Revision 3 19 PROCESSING GAIN REPORT Cisco Confidential 1 03/07/2001 Radio Circuit Description The MPI350 Spread Spectrum Transceiver operates in the 2.4 GHz ISM band, using Direct Sequence modulation techniques. The transmit/receive and data packetization operations are under the control of a protocol processor (MAC) internal to the transceiver assembly. Logic Section: A digital ASIC is employed in the logic section of the radio, providing the following functions: 1) Generation of the spreading code, combination of the code with the incoming data stream. 2) Despreading and demodulation of the incoming baseband spread signal. 3) Determination of the transmit/receive sequence. RF Section (refer to MPI350 radio block diagram): The transmitter chain includes a shaping bandpass filter followed by a vector modulator. This signal is further filtered by a saw filter at the IF frequency of 374 MHz. This signal is then mixed up to the 2400-2483.5 MHz band. A RF filter at the output of the mixer removes any other mixing products. A power amplifier chain brings the signal up to the final output level of 100 mW. Through the Tx/Rx switch, the signal is passed through a dielectric bandpass filter to the antenna port. The radio has diversity, so two antenna ports are provided. Transmitter frequency is determined by the 44.0 MHz reference oscillator, with ± 25 ppm accuracy. The receiver utilizes the same antenna filtering and Tx/Rx, followed by a LNA. A mixer circuit brings the signal to the 374 MHz IF, where a SAW filter shapes the IF spectral envelope. This filter provides the primary rejection against adjacent channel interference. An IF amplifier followed by an IF limiter brings the signal up to the level needed for the I and Q vector demodulator. A buffer amplifier and filter are used to shape the signal for the PHY digital ASIC which despreads and decodes the signal. The 374 MHz voltage controlled oscillator is controlled by a synthesizer/PLL system comprised of a prescaler and programmable dividers. The 2026-2450 MHz voltage controlled oscillator is also controlled by a synthesizer/PLL system. Both local oscillators use a reference signal for the PLL which is derived from the 44.0 MHz master reference oscillator. Cisco Confidential 2 03/07/2001 PRODUCT NAME: Cisco MPI350 Radio NAME OF TEST: The Processing Gain of a Direct Sequence System. FCC Part 15.247(e) specifies that the processing gain of a direct sequence system shall be at least 10 dB. Guidance on measurement by FCC The processing gain may be measured using the CW jamming margin method (refer to figure 1). The test consists of stepping a signal generator, in 50kHz increments, across the passband of the system. At each point, the generator level required to the produce the recommended Bit Error Rate (10-5) is recorded. This is the jammer level. The output power of the transmitting unit is measured at the same point. The Jammer to Signal (J/S) ratio is then calculated, discarding the worst 20% of the J/S data points. The total losses in a system, including transmitter and receiver, should be assumed to be no more than 2 dB. Processing Gain = S/N + Mj + Lsys Where: S/N = Signal to noise ratio required at the receiver output for 10-5 error rate of a ideal receiver for your demodulation scheme Mj = Jammer to signal ratio Lsys = System losses (2dB max) Test Results for 1 mb data rate: S/N = 13.0 dB; taken from Wireless Information Networks by Pahlavan & Levesque Mj = - 4.2 dB; worst case jamming margin from tests in lab Lsys = 2.0 dB; system losses therefore the processing gain at 1mb is 13.0 dB – 4.2 dB + 2.0 dB = 10.8 dB for 2 mb data rate: S/N = 13.0 dB; taken from Wireless Information Networks by Pahlavan & Levesque Mj = - 4.2 dB; worst case jamming margin from tests in lab Lsys = 2.0 dB; system losses therefore the processing gain at 2mb is 13.0 dB – 4.2 dB + 2.0 dB = 10.8 dB for 5.5 mb data rate: S/N = 13.6 dB; taken from Harris CCK encoding modulation Mj = - 4.9 dB; worst case jamming margin from tests in lab Lsys = 2.0 dB; system losses therefore the processing gain at 5.5mb is 13.6 dB – 4.9 dB + 2.0 dB = 10.7 dB for 11 mb data rate: S/N = 16.0 dB; taken from Harris CCK encoding modulation Mj = - 7.4 dB; worst case jamming margin from tests in lab Lsys = 2.0 dB; system losses Cisco Confidential 3 03/07/2001 therefore the processing gain at 11mb is 16.0 dB – 7.4 dB + 2.0 dB = 10.6 dB Figure 1 Signal Generator Power Meter sum split Transmitter Receiver Bit Error Rate Tester Eng: Jim NahraDate: 3/2/01 Drawn: Diane Simon Jamming Test Setup CISCO Confidential RF Systems Engineering 2.4GHz Spread Sperctrum Radio - Jammer Test Cisco Confidential 4 03/07/2001 MPI350 Spread Spectrum Transceiver Alignment Procedures ß Put the radio in Tx mode ß Set the power out (using the power meter) ß Use +20 dBm ± 1 dB for 100 mW power setting ß Use +17 dBm ± 1 dB for 50 mW power setting ß Use +15 dBm ± 1 dB for 30 mW power setting ß Use +13 dBm ± 1 dB for 20 mW power setting ß Use 0 dBm ± 1 dB for 1 mW power setting ß Turn the Tx on, ch 12-84 ß Set the power amp output power by adjusting voltage to the IF attenuator in the Tx chain.
