Description of Operation The Martec Doorminder DM-3003 is a garage door safety transmitter. It operates at 303 MHz and is mechanically activated through a motion sensor on the PCB. When the device is shaking (when the garage door is moving) the DUT transmits repetitively to a nearby receiver indicating that the garage door is in motion. When the garage door ceases motion, the DUT no longer transmits.

Liepa Valdis V. Liepa Joseph D. Brunett Research Scientist Summary Tests for compliance with FCC Regulations Part 15, Subpart C, and Industry Canada RSS-210, were performed on Martec model DM-3003. This device is subject to the Rules and Regulations as a Transmitter. In testing completed on 17-Jul-02, the device tested in the worst case met the allowed FCC specifications for radiated emissions by 1.0 dB (see p. 6). Besides harmonics, there were no other significant spurious emissions found; emissions from digital circuitry were negligible. The conducted emission tests do not apply, since the device is powered from three 1.5 VDC batteries. 2 1. Introduction Martec model DM-3003 was tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989, and with Industry Canada RSS-210, Issue 5, November, 2001. The tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-1992 "Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz". The Site description and attenuation characteristics of the Open Site facility are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref. No: IC 2057). 2. Test Procedure and Equipment Used The pertinent test equipment commonly used in our facility for measurements is listed in Table 2.1 below.

Configuration and Identification of Device Under Test The DUT is a 303 MHz transmitter, 3 x 2 x 9 inches in size. The carrier is AM modulated and LC stabilized; the modulating circuit is stabilized within the IC. The antenna is integrated into the PCB. The DUT was designed and manufactured by Martec Access Products Inc., 240 Sheffield Street, Mountainside, NJ 07092. It is identified as: Martec Access Products Transmitter Model: DM-3003 S/N or P/N: Proto FCC ID: JCQ993 IC: 1907A-993 Since the transmitter transmits continuously as long as it detects a vibration, only one transmitter was used in all of the measurements. Note: The DUT mechanically activated and ceases to transmit within 5 seconds of deactivation, see Figure 6.4. See Attachments file in this submittal for specific details about the Safety/Emergency Equipment designation for this device. 3.1 Modifications Made The R44 resistor on the DUT was changed to 604 ohms from 330 ohms after the device failed to pass the radiated emissions limits. 4. Emission Limits The DUT tested falls under the category of an Intentional Radiators and the Digital Devices. For FCC, it is subject to Part 15, Subpart C, (Section 15.231), Subpart B, (Section 15.109), and Subpart A, (Section 15.33). For Industry Canada it is subject to RSS-210, (Sections 6.1 and 6.3). The applicable testing frequencies with corresponding emission limits are given in Tables 4.1 and 4.2 below. As a digital device, the DUT is considered as a Class B device. 4.1 Radiated Emission Limits Table 4.1. Radiated Emission Limits (FCC: 15.33, 15.35, 15.109; IC: RSS-210, 6.2.2(r)).
