Engineering Test Report No. 34689-01 Measurement of RF Emissions from a Model 001D3505 Transmitter 1.0 INTRODUCTION: 1.1 Description of Test Item - This document presents the results of the series of radio interference measurements performed on a model 001D3505 Transmitter, (hereinafter referred to as the test item). No serial number was assigned to the test item. The test item is a transmitter designed to transmit at approximately 315MHz using an internal antenna. The test item was manufactured and submitted for testing by Chamberlain Manufacturing located in Elmhurst, IL. 1.2 Purpose - The test series was performed to determine if the test item meets the conducted and radiated RF emission requirements of the FCC "Code of Federal Regulations" Title 47, Part 15, Subpart C for Intentional Radiators. Testing was performed in accordance with ANSI C63.4-2003. 1.3 Deviations, Additions and Exclusions - There were no deviations, additions to, or exclusions from the test specification during this test series. 1.4 Applicable Documents - The following documents of the exact issue designated form part of this document to the extent specified herein: - Federal Communications Commission "Code of Federal Regulations", Title 47, Part 15, Subpart C, dated 1 October 2003 - ANSI C63.4-2003, "American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz" 1.5 Subcontractor Identification - This series of tests was performed by Elite Electronic Engineering Incorporated of Downers Grove, Illinois. The laboratory is accredited by the National Institute of Standards and Technology (NIST) under the National Voluntary Laboratory Accreditation Program (NVLAP). NVLAP Lab Code: 100278-0. 1.6 Laboratory Conditions - The temperature at the time of the test was 21ºC and the relative humidity was 17%. 2.0 TEST ITEM SETUP AND OPERATION: The test item is a model 001D3505 Keypad transmitter. A block diagram of the test item setup is shown as Figure 1. 2.1 Power Input - The test item was powered with 12VDC from a 12VDC battery. 2.2 Grounding - The test item was ungrounded during the tests. 2.3 Peripheral Equipment - There was no peripheral equipment submitted with the test item. Page 3 of 15

Engineering Test Report No. 34689-01 2.4 Interconnect Cables - There were no interconnect cables submitted with the test item. 2.5 Operational Mode - For all tests, the test item was placed on an 80cm high non-conductive stand. The transmit button of the test item was held down during testing thereby setting the unit to transmit continuously. The transmitting mechanism automatically deactivated when the transmit button was released. The battery voltage was periodically checked to ensure proper operation. The test was performed with the test item transmitting at 315.0MHz. 2.6 Test Item Modifications - No modifications were required for compliance to the FCC Part 15C requirements. 3.0 TEST EQUIPMENT: 3.1 Test Equipment List - A list of the test equipment used can be found on Table I. All equipment was calibrated per the instruction manuals supplied by the manufacturer. 3.2 Calibration Traceability Test equipment is maintained and calibrated on a regular basis. All calibrations are traceable to the National Institute of Standards and Technology (NIST). 3.3 Measurement Uncertainty - All measurements are an estimate of their true value. The measurement uncertainty characterizes, with a specified confidence level, the spread of values which may be possible for a given measurement system. 4.0 REQUIREMENTS, PROCEDURES AND RESULTS: 4.1 Powerline Conducted Emissions 4.1.1 Requirements - Since the test item was powered by internal batteries, no conducted emissions tests were performed. 4.2 Duty Cycle Factor Measurements 4.2.1 Procedures - The duty cycle factor is used to convert peak detected readings to average readings. This factor is computed from the time domain trace of the pulse modulation signal. With the transmitter set up to transmit for maximum pulse density, the time domain trace is displayed on the spectrum analyzer. This trace is obtained by tuning center frequency to the transmitter frequency and then setting a zero span width with 10msec/div. The amplitude settings are adjusted so that the on/off transitions clear the 4th division from the bottom of the display. The markers are set at the beginning and end of a word period. If the word period exceeds 100 msec the word period is set to 100 msec. The on-time and off-time are then measured. The on-time is total time signal level exceeds the 4th division. Off-time is time under for the word period. The duty cycle is then computed as the (On- time/ word period) where the word period = (On-time + Off-time). Page 4 of 15

Engineering Test Report No. 34689-01 4.2.2 Results - A representative plot of the duty cycle is shown on data page 11. Since the transmitters use a rolling code, the duty cycle were calculated based on the average case. With the test item transmitting at 315.0MHz, the average duty cycle was determined to be -8.5dB. The average case duty cycle was supplied by Chamberlain. 4.3 Radiated Measurements 4.3.1 Requirements - The test item must comply with the requirements of FCC "Code of Federal Regulations Title 47", Part 15, Subpart C, Section 15.205 et seq.: Paragraph 15.231(b) has the following radiated emission limits: Fundamental Field Strength Frequency Field Intensity Harmonics and MHz uV/m @ 3 meters Spurious @ 3 meters 260 to 470 3,750 to 12,500* 375 to 1,250* * - Linear Interpolation For 315.0MHz, the limit at the fundamental is 6041.7uV/m @ 3m and the limit for the harmonics is 604.2uV/m @ 3m. In addition, emissions appearing in the Restricted Bands of Operation listed in paragraph 15.205(a) shall not exceed the general requirements shown in paragraph 15.209. 4.3.2 Procedures - Open field measurements were performed in a 32ft. x 20ft. x 14ft. high shielded enclosure. The shielded enclosure prevents emissions from other sources, such as radio and TV stations from interfering with the measurements. All powerlines and signal lines entering the enclosure pass through filters on the enclosure wall. The powerline filters prevent extraneous signals from entering the enclosure on these leads. A preliminary radiated emissions test was performed to determine the emission characteristics of the test item. For the preliminary test, a broadband measuring antenna was positioned at a 3 meter distance from the test item. The entire frequency range from 30MHz to 4.0GHz was investigated using a peak detector function. The data was then processed by the computer to calculate equivalent field intensity. The final open field emission tests were then manually performed over the frequency range of 30MHz to 4.0GHz. Between 30MHz and 1000MHz, a tuned dipole antenna was used as the pick-up device. A broadband double ridged waveguide antenna was used as the pick-up device for all frequencies above 1GHz. All significant broadband and narrowband signals were measured and Page 5 of 15

Engineering Test Report No. 34689-01 recorded. The peak detected levels were converted to average levels using a duty cycle factor which was computed from the pulse train. To ensure that maximum or worst case, emission levels were measured, the following steps were taken: (1) The test item was rotated so that all of its sides were exposed to the receiving antenna. (2) Since the measuring antenna is linearly polarized, both horizontal and vertical field components were measured. (3) The measuring antenna was raised and lowered from 1 to 4 meters for each antenna polarization to maximize the readings. (4) For hand-held or body-worn devices, the test item was rotated through three orthogonal axes to determine which orientation produces the highest emission relative to the limit. 4.3.3 Results - The preliminary plots, with the test item transmitting at 315MHz, are presented on pages 12 and 13. The plots are presented for a reference only, and are not used to determine compliance. The final open area radiated levels, with the test item transmitting at 315.0MHz, are presented on page 14. As can be seen from the data, all emissions measured from the test item were within the specification limits. The emissions level closet to the limit (worst case) occurred at 315.0MHz. The emissions level at this frequency was 5.9 dB within the limit. Photographs of the test configuration which yielded the highest or worst case, radiated emission levels are shown on Figure 2. 4.4 Occupied Bandwidth Measurements 4.4.1 Requirement - In accordance with paragraph 15.231(c), all emissions within 20dB of the peak amplitude level of the center frequency are required to be within a band less than 0.25% of the center frequency wide. 4.4.2 Procedures - The test item was placed on an 80cm high non-conductive stand. The unit was set to transmit continuously. With an antenna positioned nearby, occupied bandwidth emissions were displayed on the spectrum analyzer. The resolution bandwidth was set to 30 kHz and span was set to 2 MHz. The frequency spectrum near the fundamental was plotted. 4.4.3 Results - The plot of the emissions near the fundamental frequencies is presented on page 15. As can be seen from the data page, the transmitter met the occupied bandwidth requirements. Page 6 of 15
