It is intended to provide hands-free functionality for cell phone users. To achieve this, a Base Unit is connected to a cell phone headset output via a cable. When a call is initiated, the audio signal is carried by the cable from the phone to the Base Unit. The base unit then transmits the signal to the Wireless Headset Unit, mounted on the user’s ear, where it is converted back to audio. Both the Wireless Headset Unit and the Base Unit are transceivers. This report represents testing of the Base Unit. A production version of the EUT arrived on July 1, 2003, in Good condition. The EUT was assigned serial number 0001. Note that the EUT is battery powered and therefore line-conducted emissions testing was not required. The EUT has been tested at the request of Company:Aura Communications, Inc. 187 Ballardvale Street Wilmington, MA, 01887 Name of contact:Aron Viner Telephone:(978) 527-4130 Fax:(978) 988-3977 During testing, the EUT was activated from a fresh battery and was transmitting continuously. The EUT was manipulated in 3 orthogonal axes to determine a worst case orientation, and was rotated through 360 degrees to maximize emissions. Intertek Testing Services, NA, Inc.70 Codman Hill Road Boxborough MA 01719 Aura Communications, Inc., Model No. AD688B-XDate of Test: July 1-2, 2003 FCC ID: P6YAD688B Report # 30448705FCC Part 15.209 2.2Related Submittal(s) Grants An application for the Wireless Headset Unit was filed at the same time as this application, under the FCC ID: P6YAD688H. 2.3Test Facility Site 2C (Middle Site) is a 3m and 10m sheltered EMI measurement range located in a light commercial environment in Boxborough, Massachusetts. It meets the technical requirements of ANSI C63.4-1992 and CISPR 22:1993/EN 55022:1994 for radiated and conducted emission measurements. The shelter structure is entirely fiberglass and plastic, with outside dimensions of 33 ft x 57 ft. The structure resembles a quonset hut with a center ceiling height of 16.5 ft. The testing floor is covered by a galvanized sheet metal groundplane that is earth-grounded via copper rods around the perimeter of the site. The joints between individual metal sheets are bridged with a 2 inch wide metal strips to provide low RF impedance contact throughout. The sheets of metal are screwed in place with stainless steel, round-head screws every three inches. Site illumination and HVAC are provided from beneath the ground reference plane through flush entry ports, the port covers are electically bonded to the ground plane. A flush metal turntable with 12 ft. diameter and 5000 lb. load capacity is provided for floor-standing equipment. A wooden table 80 cm high is used for table-top equipment. The turntable is electrically connected to the ground plane with three copper straps. The straps are connected to the turntable at the center of it with ground braid. It is copper strap is directly connected to the groundplane at the edges of the turntable. The turntable is located on the south end of the structure and the antennas are mounted 3 and 10 meters away to the north. The antenna mast is a non-conductive with remote control o…

Noticed odd peak structure with max peak offset from the fundamental by ~100-150 kHz. Fundamental was verified as actual peak emission when transmitting appropriate audio data stream through the unmodified unit; data for output power taken on the continuously transmitting version agrees with the level of the unmodified unit and therefore will be used.
