Thank you for purchasing Find One, Find All® XD (or FOFA® for short), the only key finder and remote control locator with Radio Proximity Detection.(XD) FOFA is expandable to 36 unique units and doesn’t require a “base” to locate the items like previous key finders. Simple to setup and use, use FOFA on your keys, wallet, remotes, cell phones, MP3 players, backpacks, or anything else that you misplace. If you can’t wait to start using your FOFA’s, go to Quick Start. For a more in-depth understanding of your FOFA’s, see Setting up Your FOFA’s.

Model Number: KXD-27 FCC ID: B4SKXD-27 Type: Pulsed Transmitter / UHF ASK Receiver Power Requirements: 3V CR2032 battery Frequency of Operation: 433.8 MHz Applicable Rule Section: Part 15, Subpart C, Section 15.231 Tests Performed Transmitter: Para. 15.231(a), Radiated Emissions, Fundamental and Harmonics Transmitter: Para. 15.231(b), Radiated Emissions, Spurious Case Transmitter: Para. 15.231(b), Duty Cycle Determination Transmitter: Para. 15.231(c), Occupied Bandwidth Receiver: Para. 15.109(a) Receiver Radiated Spurious Emissions Retlif Testing Laboratories, Test Report R-11836-1, X10 (USA), Inc., FCC ID: B4SKXD-27 Page 2 of 23 Test Results Transmitter: 15.231 (a): This device transmits a control signal and is used as an: remote control transmitter. 15.231 (a)(1) The transmitter is manually operated. Transmission ends within 5 seconds of deactivation. 15.231 (a)(3): The transmitter does not perform periodic transmissions or the transmitter performs periodic transmissions at predetermined intervals greater than 1 hour apart and are shorter than 1 second in duration. 15.231 (b): The fundamental field strength did not exceed 10991.7 μV/M (Average) at a test distance of 3 meters. In addition, the requirements of section 15.35 for averaging pulsed emissions and for limiting peak emissions were met. The field strength of harmonic and spurious emissions did not exceed 1099.1 μV/M (AVERAGE). 15.231 (c) The Bandwidth of the emission was no wider than 0.25% of the center frequency 51 kHz) as measured 20 db down from the modulated carrier. Receiver: 15.109(a): The field strength of spurious radiated emissions did not exceed Class B limits specified in paragraph 15.109(a). Retlif Testing Laboratories, Test Report R-11836-1, X10 (USA), Inc., FCC ID: B4SKXD-27 Page 3 of 23 Determination of Field Strength Limits The field strength limits shown below are found in Section 15.231: Frequency Limit F1 = 260 3750 = L1 Fo = 433.8 MHz Lo F2 = 470 12500 = L2 The formula below was utilized to determine the limits: Limit = L1 + [(Fo-F1)(L2-L1)/(F2-F1)] Solving Yields Fundamental Limit = 10991.7 μV/M (AVERAGE) @ 3 Meters Harmonic Limit = 1099.1 μV/M (AVERAGE) @ 3 Meters Duty Cycle Determination The unit’s RF output was directly coupled to the input of the spectrum analyzer. The analyzer was set for a frequency span of 0 Hz. The sweep time was then adjusted in order to display one full pulse train. The transmitter on time was then summed and compared to the time for one full cycle in order to obtain the duty cycle. (See plots for additional information.) Transmitter On Time =44.1 milliseconds (maximum per cycle) Transmitter Cycle Time = 115.8 milliseconds (100 ms maximum) Transmitter Duty Cycle =44.1 % Calculation 1 Large Pulse =1.7 milliseconds 53 x 800.0 μs (small pulse) =42.4 milliseconds 1.7 + 42.4 =44.1 milliseconds Duty Cycle (44.1/100)*100 =44.1 % Correction Factor =20 log (0.441)=-7.1 dB Retlif Testing Laboratories, Test Report R-11836-1, X10 (USA), Inc., FCC ID: B4SKXD-27 Page 4 of 23 Spectrum Analyzer Desensitization Considerations Due to the nature of the emissions being measured, care was taken to ensure that the resolution bandwidth of the spectrum analyzer was adequate to provide accurate measurements. The following formula was utilized: minimum bandwidth = 1/{minimum pulse width (in seconds) x 1.5} = Hz Setting pulse desensitization equal to zero and utilizing the minimum observed pulse width of 800.0 μs yields a minimum required bandwidth of 833.3 Hz. FCC specified bandwidths of 100 kHz and 1 MHz were utilized below and above 1 GHz, respectively. General Notes 1. All readings were taken utilizing a peak detector function at a test distance of 3 meters. 2. The duty cycle was applied to the peak readings in order to determine the average value of the emissions. 3. The frequency range was scanned from 30 MHz to 4.34 GHz. All emissions not reported were more than 20 dB below the specified limit. 4. The Receiver was tested per “ANSI STANDARD C63.4-2003 12.1.1.2. The receiver was programmed for normal receiver mode. Normal mode is defined as the unit energized continuously for 10 ms, then off for 2.4 seconds.
