PUBLIC NOTICE Federal Communications Commission 445 12th St., S.W. Washington, D.C. 20554 News Media Information 202 / 418-0500 Fax-On-Demand 202 / 418-2830 TTY 202 / 418-2555 Internet: http://www.fcc.gov ftp.fcc.gov DA 00- 2225 September 28, 2000 OET Extends Effective Date of Antenna Connector Requirement Indefinitely On May 22, 2000, the Office of Engineering and Technology, OET, issued a Public Notice, DA 00-1087, clarifying 47 CFR 15.203. This rule requires transmitters authorized under Part 15 to be designed in such a way as to ensure that no antenna, other than that furnished by the responsible party, can be used with the device. Typically, a manufacturer will either design a unique antenna connector or modify a commonly available connector to satisfy this requirement. In the Public Notice, we noted several antenna connectors, that were once considered unique, have since become common place and no longer satisfy the requirement of this rule section. Hence, effective 30 days after the date of the Public Notice, these antenna connectors would no longer be acceptable for satisfying the requirement in Section 15.203. On June 22, 2000 we extended the effective date of the antenna connector requirement in the Public Notice to October 1, 2000. However, a Petition for Reconsideration has been filed and, in order to consider the merits of the Petition, we are extending the effective date of the Public Notice indefinitely. After a decision on the merits of the Petition has been made, we will address the need for a new effective date regarding DA 00-1087. Thus, we are extending the effective date of Public Notice, DA 00-1087, indefinitely. For further information concerning this Public Notice, contact Joe Dichoso at the FCC Laboratory, 7435 Oakland Mills Road, Columbia, Md. 21046, (301) 362-3024, or e-mail: [email protected].

The test report is based on testing performed by Compatible Electronics personnel according to the measurement procedures described in the test specifications given below and in the "Test Procedures" section of this report. The measurement data and conclusions appearing herein relate only to the sample tested and this report may not be reproduced in any form unless done so in full with the written permission of Compatible Electronics. This report must not be used to claim product endorsement by NVLAP or any other agency of the U.S. Government. Device Tested: Linx RF Transceiver Model: TR-900-MC-PA S/N: 3 Product Description: See Expository Statement. Modifications: The EUT was modified during the testing. Please see the list located in Appendix A. Manufacturer: Linx Technologies 575 SE Ashley Place Grants Pass, OR 97526 Test Dates: September 28 and October 2, 2000 Test Specifications: EMI requirements CFR Title 47, Part 15 Subpart C, Sections 15.205, 15.209, and 15.249 Test Procedure: ANSI C63.4: 1992 Test Deviations: The test procedure was not deviated from during the testing. SUMMARY OF TEST RESULTS TEST DESCRIPTION RESULTS 1 Conducted RF Emissions, 450 kHz - 30 MHz This test was not performed because the EUT is powered by a nine volt battery. 2 Radiated RF Emissions, 10 kHz - 9300 MHz Complies with the limits of CFR Title 47, Part 15, Subpart C, sections 15.205, 15.209, and 15.249 FCC ID: OJM-TR-900-MC Report No.: B01002D1 114 OLINDA DRIVE, BREA, CALIFORNIA 92823 PHONE: (714) 579-0500 FAX: (714) 579-1850 Page 5 of 16 1.
