American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 August 27, 2004 RE: SerComm Corp. FCC ID: P27IP806GA-1 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Users manual states typical output power is +13 dBm, while measured power is significantly above this (20.35 dBm). Please explain and/or correct the affected exhibits. 2) The FCC ID given in the test report is not correct. 3) Please confirm that a DoC has been performed for this device using an accredited test lab and the minimum test configuration per ANSI C63.4. 4) FYI....If the device is also been approved using a DoC, then the users manual must include the following on a single page. Please be sure the manufacturer includes this information with each device shipped. COMPLIANCE INFORMATION FOR DoC AUTHORIZATIONS (47CFR 2.1077) If a product is tested and authorized under a Declaration of Conformity, a compliance information statement shall be supplied with the product at the time of marketing or importation, containing the following information on a single page : (1) Identification of the product, i.e. name and model number. (2) A statement similar to that contained in Section 15.19(a)(3) that the product complies with Part 15 of the regulations. (3) The identification, by name, address and telephone number, of the responsible party. The responsible party is defined as either the manufacturer, or if the equipment is imported, the importer. The responsible party for a Declaration of Conformity must be located within the United States. Timothy R. Johnson Examining Engineer 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.

Dear Tim: I've re-uploaded two new files to your website. Regarding to comments No.1, 3and 4, I have corrected the Output Power to 20.5 dBm in the "users maunal-new", and added some compliance informations of manufacturer with the title "DECLARATION OF CONFORMITY" on the page 2 of the user's manual. And about the comments No. 2, I've modified the wrong FCC ID to the correct one also. Please check them again and thanks for your help. Best Regards
