FCC ID: MSQDCW615 User Manual additionally: 15.21 CAUTION: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Prohibition of co-location This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. 15.105 Federal Communications Commission (FCC) Requirements, Part 15 This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ---Reorient or relocate the receiving antenna. ---Increase the separation between the equipment and receiver. ---Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. ---Consult the dealer or an experienced radio/TV technician for help. Caution Statement of the FCC Radio Frequency Exposure This Wireless LAN radio device has been evaluated under FCC Bulletin OET 65C and found compliant to the requirements as set forth in CFR 47 Sections 2.1091, 2.1093, and 15.247(b)(4) addressing RF Exposure from radio frequency devices. The radiation output power of this Wireless LAN device is far below the FCC radio frequency exposure limits. Nevertheless, this device shall be used in such a manner that the potential for human contact during normal operation—as a mobile device but use in a body-worn way is strictly prohibit. When using this device, a certain separation distance between antenna and nearby persons has to be kept to ensure RF exposure compliance. In order to comply with the RF exposure limits established in the ANSI C95.1 standards, the distance between the antennas and the user should not be less than 20cm. Regulatory information / Disclaimers Installation and use of this Wireless LAN device must be in strict accordance with the instructions included in the user documentation provided with the product. Any changes or modifications (including the antennas) made to this device that are not expressly approved by the manufacturer may void the user’s authority to operate the equipment. The manufacturer is not responsible for any radio or television interference caused by unauthorized modification of this device, or the substitution of the connecting cables and equipment other than manufacturer specified. It is the responsibility of the user to correct any interference caused by such unauthorized modification, substitution or attachment. Manufacturer and its authorized resellers or distributors will assume no liability for any damage or violation of government regulations arising from failing to comply with these guidelines. MPE Statement (Safety Information) Your device contains a low power transmitter. When device is transmitted it sends out Radio Frequency (RF) signal. Safety Information CAUTION: To maintain compliance with FCC’s RF exposure guidelines, this equipment should be installed and operated with minimum distance 20cm between the radiator and your body. Use on the supplied antenna. Unauthorized antenna, modification, or attachments could damage the transmitter and may violate FCC regulations.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 March 15, 2003 RE: ASUSTek Computer Inc. FCC ID: MSQDCW615 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please provide a photograph of the label of the PC card which shows its FCC ID Number. Note the label of the cable modem references FCC ID: QDWAB008WN100. 2) The operational description was uploaded as confidential, but not listed in the confidentiality letter. Please confirm if this exhibit is considered confidential and if so, please updated the confidentiality letter. 3) The parts list is not necessary. Please correct the confidentiality letter by removing this. 4) Please provide the schematics for the PCMCIA card. 5) Since the device is mobile, please provide a standard MPE calculation exhibit. The one provided is not preferred since the device should easily meet with standard calculations. 6) The DoC statement page must also include the following: A statement similar to that contained in Section 15.19(a)(3) that the product complies with Part 15 of the regulations. 7) The users manual is missing the statements required by 15.21 and 15.105. Additionally, the users manual is missing information regarding RF exposure statements. 8) Please explain what precautions are built into the device so that it only functions with the particular PCMCIA card specified. 9) Please provide information regarding the VBW and RBW of the plots provided at the bandedge. Additionally, compliance at the 2.4835 GHz (Channel 11) band has not been shown. It appears that the plot for the 2.4 GHz was provided twice. 10) Although conducted emissions were performed, it is also recommended that the conducted emissions meet the future limits (CISPR) that will be required in the next few years. Please confirm if additional test data will be provided for this, or proceed with the current data. This is because the grant will be issued with one of the following grant notes depending on which set of limits it is shown to have met: Current Limits NOTE: The manufacture and importation of this device must cease on July 10, 2005 pursuant to 15.37(j) or 18.123 transition provisions adopted under FCC 02-157 (ET Docket 98-80). Future Limits (CISPR) NOTE: This device has shown compliance with the conducted emissions limits in 15.107, 15.207, or 18.307 adopted under FCC 02-157 (ET Docket 98-80) and may be marketed after July 11, 2005 and is not affected by the 15.37(j) or 18.123 transition provisions.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 March 25, 2003 RE: ASUSTek Computer Inc. FCC ID: MSQDCW615 After a review of the submitted information, I have a few comments on the above referenced Application. 1) The users manual is missing the prohibition of co-location information as part of the RF exposure statements. Please add the following to the users manual, " This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter". 2) Please remove the reference to "portable" in the Caution Statement of the FCC Radio Frequency Exposure portion of the users manual. This device is considered as a mobile device only. 3) The label states the TX is optional. Please explain if the PCMCIA card is always included with the Cable Modem when sold. Are they always packaged together? If not, please explain how the device is built (using software/hardware blocks, etc) so that a user can only use the PCMCIA cards intended by the manufacturer and not any PCMCIA card they desire. 4) The conducted emissions provided do not show any reading from 150 kHz to 450 kHz. Due to the data given in the tables and the test method specified in 4.1 of the test report, it appears that the device was only tested from 450 kHz - 30 MHz to the older FCC limits. Please confirm if additional test data will be provided to show compliance with the new limits (0.150 - 0.450 MHz was not previously tested), or if we should proceed using the current data. This is because the grant will be issued with one of the following grant notes depending on which set of limits it is shown to have met: Current Limits NOTE: The manufacture and importation of this device must cease on July 10, 2005 pursuant to 15.37(j) or 18.123 transition provisions adopted under FCC 02-157 (ET Docket 98-80).

Foreword In adopt with the Human Exposure IEEE C95.1, and according to the FCC 1.1310. The Maximum Permissible Exposure (MPE) is obligated to measure in order to prove the safety of radiation harmfulness to the human body. The Gain of the antenna used is measured in an Anechoic chamber. The maximum total power to the antenna is to be recorded. By adopting the Friis Transmission Formula and the power gain of the antenna, we can find the distance right away from the product, where the limit of the MPE is. 2.
