The same type as specified by the manufacturer can only replace these antennas; therefore, it meets the requirements of this section. The ZT contains two antennas for diversity purposes, only one antenna transmits during normal operation. § 15.307 Coordination with fixed microwave service Enclosed on the following page is the UTAM affidavit stating compliance to this section.

COMMUNICATION CERTIFICATION LABORATORYTEST REPORT: 73-7001 FCC ID: AY5SN999CSEQ Page 94 of 98 Exhibit 11 Exhibit 11: RF Exposure/Environmental Evaluation Section 15.319 (i) Requirement: Unlicensed PCS devices are subject to the radiofrequency radiation exposure requirements specified in '' 1.1307(b), 2.1091 and 2.1093 of this chapter, as appropriate. All equipment shall be considered to operate in a “general population/uncontrolled” environment. Applications for equipment authorization of devices operating under this section must contain a statement confirming compliance with these requirements for both fundamental emissions and unwanted emissions. Technical information showing the basis for this statement must be submitted to the Commission upon request. Demonstration of Compliance: The SN999CSEQ is classified as a mobile device, which is installed so that a minimum separation distance of 20 centimeters is maintained between the transmitter’s radiating structure and the body of the user or nearby persons, and the ERP of the SN99CSEQ is less than 3 watts. Therefore, the SN99CSEQ is categorically excluded from routine environmental evaluation for RF exposure as per ' 2.1091(c). The installation manual contains the following statement to instruct the installer that the 20 centimeter separation distance must be maintained in order to comply with the RF exposure requirement. Warning: Note to installers: In order to comply with the FCC RF exposure requirements the ZT must be installed with a minimum separation distance of 20 cm from the antennas to the user or nearby persons. The ZT contains two antennas for diversity purposes, only one antenna transmits during normal operation.

Specific identifying information for the device tested is given below. -ApplicantNEC AMERICA, INC. 1555 Walnut Hill Lane Irving, TX 75038 -Manufacturer:NEC Corporation 7-1 5 Chome Shiba Minato-Ku Tokyo, 108-01 Japan -Trade Name:NEC -Model Number:SN999CSEQ -FCC ID Number:AY5SN999CSEQ On this 12 th day of October 1999, I, individually, and for Communication Certification Laboratory, certify that the statements made in this engineering report are true, complete, and correct to the best of my knowledge, and are made in good faith. COMMUNICATION CERTIFICATION LABORATORY Checked by: William S. Hurst, P.E. Vice President Tested by: Roger J. Midgley EMC Manager COMMUNICATION CERTIFICATION LABORATORYTEST REPORT: 73-7000 FCC ID: AY5SN999CSEQ Page 10 of 98 Exhibit 6 SECTION 1 GENERAL INFORMATION 1.1 Product Description The SN999CSEQ is the base station (ZT) portion of a wireless PBX system. The system consists of a PBX, Wireless Communication system (WCS) (installed inside of the PBX), ZT and handset (PS). The ZT’s are installed throughout the coverage area and hard wired to the base station controller. The user carries a wireless PS that allows the user access to the PBX functions from any location within the coverage area. This application is for the ZT (s interface), which is identified by FCC ID: AY5SN999CSEQ. There is a second ZT (u interface) which is being submitted concurrently with this application is identified by FCC ID: AY5SN992CSEO. These ZT’s are functional the same as the previously certified ZT (FCC ID: AY5SN933WEK) and PS (FCC ID: AY5SN531PSTH); therefore, they can be installed with these previously certified ZT and PS. 1.2 Test Specification The SN999CSEQ is an Isochronous device that operates in the 1920-1930 MHz sub-band; therefore the SN999CSEQ is subject to the provisions of FCC Part 15, Subpart D. Unlicensed Personal Communications Service Devices. 1.3 Test Methods & Procedures The SN999CSEQ was tested in accordance with ANSI C63.17- 1998.
