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. The measurement uncertainty for these tests is presented below: Conducted Emission Measurements Combined Standard Uncertainty 1.07 -1.07 Expanded Uncertainty (95% confidence) 2.1 -2.1 Radiated Emission Measurements Combined Standard Uncertainty 2.26 -2.18 Expanded Uncertainty (95% confidence) 4.5 -4.4 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 are required. 4.2 Duty Cycle Factor Measurements: Page 5 of 17

Engineering Test Report No. 36583-01 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). 4.2.2 Results: A representative plot of the duty cycle is shown on data page 12. Since the transmitter uses a rolling code, the duty cycle correction factor used was calculated based on the average case. The following average case information was supplied by Chamberlain Manufacturing: An average ON time is used because of the ever changing rolling code. For 100 msec period: 1msec average sync pulse (50% of the time the sync pulse is 0.5msec and 50% of the time the sync pulse is 1.5msec) 20 digits for a total time of 40 msec, but only half of them are ON (oscillator running) for an average of 20 msec. 59msec average blanktime The total is 100msec. 20 log 21/100 = -13.5 With the test item transmitting at 315MHz, the average case duty cycle correction factor would be -13.5dB.

Engineering Test Report No. 36583-01 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 315MHz, the limit at the fundamental is 6041.7uV/m @ 3m and the limit on 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 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 Page 7 of 17

Engineering Test Report No. 36583-01 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 data pages 14 and 15. 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 315MHz, are presented on data page 16. 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 4.9dB within the limit. See data page 16 for details. 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 frequency are presented on data page 17. As can be seen from this data page, the transmitter met the occupied bandwidth requirements. In addition, the 99% emission bandwidth measured 214kHz when using the analyzer’s special function key. 5.0 CONCLUSIONS: With modifications made to the test item by Chamberlain Manufacturing personnel, it was Page 8 of 17

Engineering Test Report No. 36583-01 determined that the Chamberlain Manufacturing Model 1A6346, did fully meet the conducted and radiated emission requirements of the FCC "Code of Federal Regulations" Title 47, Part 15, Subpart C, Section 15.205 et seq. for Intentional Radiators, when tested per ANSI C63.4-2003. 6.0 CERTIFICATION: Elite Electronic Engineering Incorporated certifies that the information contained in this report was obtained under conditions which meet or exceed those specified in the test specifications.
