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. If not installed and used in accordance with the instructions, it 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 and correct the interference by one or more of the following measures: 1. Reorient or relocate the receiving antenna. 2. Increase the distance between the equipment and the receiver. 3. Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. 4. Consult the dealer or an experienced radio/TV technician for help. Export restrictions This product or software contains encryption code which may not be exported or transferred from the US of Canada without an approved US Department of Commerce export license. Safety Statements Federal Communications Commission Statement This device complies with FCC Rules Part 15. Operation is subject to the following two conditions: · This device may not cause harmful interference, and · This device must accept any interference received, including interference that may cause undesired operation. SAFETY INFORMATION Your device contains a low power transmitter. When device is transmitted it sends out radio frequency (RF) signal. 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. Table of Contents 1.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 July 9, 2002 RE: FCC ID: L8G8800002 Attention: Eric Wong I have a few comments on this Application. 1 The following documents can not be uploaded to the FCC because they contain Asian fonts; The Operational Description, the Parts List (BOM), the RF exposure, the Test Report and the User’s Manual. The FCC copy of adobe acrobat does not have the capability of reading these fonts. Please provide these documents without Asian fonts. xx 2 Section II of the report states the device is compliant to the antenna rules of 15.203 because it contains only an integral antenna and no other antenna can be used with the device. However the schematics appear to show a printed circuit board antenna (integral) and two selectable external antenna jack connections. In fact, J3 appears to be able to be selected at the same time as the printed circuit antenna. This means that there is a possibility for them to in collocation. This is not allowable under current FCC rules. Also, there appears to be another external antenna connection in J2. Please provide evidence that the statement in the report is accurate. This includes providing schematics that show how these other 2 external capable antenna connections are to be eliminated. This also includes evidence showing how the manufacturer will prevent both the circuit board antenna and the antenna connection of J3 from simultaneous selection and operation. xx 3 The device and the label location appear to be sufficiently large to accommodate the FCC ID number and the 2-condition statement per 15.19. Please provide a label that meets the requirements of 15.19 and 2.925. xx 4 In the RF exposure calculations you inadvertently used the dBm rather than the mW level. You also used a gain of isotropic (1) yet the antenna is said to be a dipole. Please correct the RF exposure statement to reflect the actual power measure at the antenna terminal and the actual gain of the dipole antenna used. xx 5 In the chart on page 40 of the report you state a level for Power Spectral Density in dBuV, however, the SA picture on page 41 is correct using dBm. Please note that PPSD is dBm. Please correct the chart to reflect the proper unit of measurement. xx Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

Those 5 documents aren’t having any Chinese character but anyway I have re-do the conversion of the document by the Acrobat Distiller and it will be expected to work for the problem you’d encountered. 2. Referring to the diversity of the antennas, these any possibility of using any other antennas are not applied to this model but maybe for the other model to be manufactured in the future based on the same PCB of the model we are applying. The manufacturer, LANTECH Advance Corp., claims that if these any other model with those modifications will be apply separately in the future. 3. The label is already shown the FCC ID and comply with the 2.925; Regarding to the remarks of 15.19, the label will be modified as the uploads. 4. Please find the file uploaded. 5. The pages about the Power Spectral Density is modified, please find it in the uploads Should you have any questions, please don’t hesitate to ask us. Sincerely yours, Eric Wong Project Engineer Training Research Co Ltd.
