Kelkhoff Manager, Product Safety THEORY OF OPERATION AND CIRCUIT DESCRIPTION MODEL 1A5247 3 FUNCTION, REMOTE CONTROL TRANSMITTER (Please refer to enclosed schematic drawing: 195D1255D) The 1A5247 transmitter consists of a low power RF oscillator (Q1 and associated components), a digital encoder (U1 and related components), and on/off switches. The RF oscillator, Q1, is of the grounded base type. C4, C5, C6, C7, and the copper loop, L2, set the center frequency of the oscillator at 390 MHz. C3, L1, L2 and C2, with the internal capacitance of Q1, establish feedback levels and harmonic suppression. R3, R4 and R6 establish dc operating conditions on Q1 and help improve temperature stability. U1 and related components generate a digital code. This code is used in the companion receiver to identify a particular transmitter or functions. The 3V battery circuit is equipped with an automatically releasing (normally off) push-button switches. D1, D2, and D3 supply voltage to Q1 and U1 when SW1, SW2 or SW3 are depressed. SW1-SW3, and related components, R1, R2, R7-R9 and and U1 provide three input functions. The digital signal at U1 (pin 1) is randomly programmed at our factory location. 1. EXPOSITORY STATEMENT 2. THEORY OF OPERATION 3. SCHEMATIC 4. PHOTOGRAPHS 5. FCC LABEL DRAWING 6.

The associated control receiver is part of this system, and has been certified at an earlier date. L. S. COMPLIANCE, Inc. FCC ID: HBW1A5247 LSC-Chamberlain 80232of 25 6 1.4 INTRODUCTION On November 2 and 11 of 1998, a series of Radiated Emissions tests were performed on a sample model of the Craftsman 3 button Remote, a Remote control which operates a garage door by means of a short burst of data transmission containing an I.D. code. These tests were performed using the test procedures outlined in ANSI C63.4-1992 for intentional radiators, and in accordance with the limits set forth in FCC Part 15.231a,b for a periodic transmitter. These tests were performed by Kenneth L. Boston, PE, of L. S. Compliance, Inc. 1.5 PURPOSE The above mentioned tests were performed in order to determine the compliance of Craftsman 3 button Remote product with limits contained in various provisions of Title 47 CFR, FCC Part 15, including: 15.20515.231b 15.209 15.231c All radiated emissions tests were performed to measure the emissions in the frequency bands described by the above sections, and to determine whether said emissions are below the limits established by the above sections. These tests were performed in accordance with the procedure described in the 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 (ANSI C63.4-1992). Another document used as reference for the EMI receiver specification was the International Special Committee on Radio Interference (CISPR) number 16-1 (1993). 1.6 RADIATED EMISSIONS TEST SETUP The test sample was operated within the 3 meter Semi-Anechoic, FCC listed chamber located at L.S. Compliance in Cedarburg, WI. The sample was placed on an 80cm high wooden pedestal, which was centered on the flush-mounted 2m diameter metal turntable. The test sample was operated on its own [new] internal battery. The test sample was configured to run in a continuous transmit mode during the 15.231c and 15.231b measurements. This was accomplished by the use of a small Plexiglas stand, which had a plastic plunger simulating a finger, which held down on of the activating buttons. The three buttons were all activated to transmit, and the large button gave the highest emission signature, and was used for all the testing. One test sample, set to operate on the standard channel, was tested as an intentional radiator, in order to determine compliance at a frequency of 390 MHz, Please refer to Section 1.11 for pictures of the test setup. L. S. COMPLIANCE, Inc. FCC ID: HBW1A5247 LSC-Chamberlain 80232of 25 7 1.7 RADIATED EMISSION TEST PROCEDURE The fundamental and spurious (harmonic) emissions of the transmitter were tested for compliance to Title 47 CFR, FCC Part 15.231b limits for periodic devices. For the calculations used to determine the limits applicable for the test sample, refer to Appendix A. These limits are expressed in decibels (dB) above 1 microvolt per meter (μV/m). The sample was tested from the lowest frequency generated by the transmitter (without going below 9 kHz) to the 10th harmonic of the fundamental frequency generated by the device. The appropriate limits were also observed when the fundamental or spurious signals were located within any of the restricted bands as described in Part 15.205a. These frequencies, and their associated limits, are referenced in Section 7.10. The sample was placed on a nonconductive (wooden) pedestal in the 3 Meter chamber and the antenna mast was placed such that the antenna was 3m from the test object. A biconical antenna or tuned dipole was used to measure emissions from 30 to 200 MHz, a …
