SAI SAAR ASSOCIATES, INC., 37 Todd Ridge Rd., Titusville, NJ 08560 TELEPHONE (609) 818-0860 FAX (609) 818-0861 E-mail [email protected] March 30, 2004 CONFIDENTIAL- FOR ITS USE ONLY TECHNICAL DESCRIPTION REMOTE CONTROL TRANSMITTER Introduction This transmitter sends remote control commands to products such as window shades, blinds, lights, and other similar devices. The transmitter operates at 433.42 MHz. The control signal consists of a control word, a sequence number to distinguish each button push, a transmitter identification number and a checksum for error control. The modulation is on-off keying with an average duty cycle of about 50 percent. Each data packet lasts for about 140 milliseconds. Packets are sent so long as one of the user push buttons is pressed, and stops when the button is released. Even if a button is continuously pressed as in a stuck switch, the transmitter output will stop in about 10 seconds until the button is released and pressed again. Technical Specifications Transmitter frequency 433.42 MHz +/- 200 kHz Transmitter stabilization SAW resonator Microcontroller clock 1.00 MHz +/- 0.5% ceramic resonator Modulation On\ off keying Data rate Approximately 1 kbps Power source 1 Lithium coin cell type 2450 Circuit Description The transmitter uses a standard Colpits oscillator, the frequency of which is controlled by a SAW resonator. A second stage is an amplifier used to isolate the oscillator from the antenna. The antenna is a wire about 5 inches long. The circuit is controlled by an 8 bit microcontroller. The microcontroller clock uses a 1 MHz ceramic resonator as the frequency determining element. When a used button switch is pressed, the microcomputer is woken up from sleep and turns the transmitter on and off to send the signal indicating which button is pressed. Transmission occurs only while a button is held down. If a button is held down continuously, transmission stops after approximately 10 seconds.

It sends control and identification signals only. The transmitter fundamental frequency is 433.42 MHz. EUT was activated for all testing from new batteries. The EUT has been tested at the request of Company:Harmonic Design, Inc. 12190 Tech Center Drive Poway, CA, 92064 Name of contact:Mr. Eric Hauck Telephone:(858) 391-9085 Fax:(858) 391-9087 2.2Related Submittal(s) Grants None. 70 Codman Hill Road Boxborough MA 01719 Date of Test: March 22, 2004 EMC Report for Harmonic Design, Inc., on the Model: SOMFY Report # 3056237.01Page 4 of 13FCC Parts 15 B & C Certification 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 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 electrically 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. A 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 of antenna height and polarization. The antenna height is a…
