T:\M\Mr._Butler_Co\1686AT4\Operational Description Xmit.doc Rev. 1/1/03 Operational Description The Mr. Butler Remote is a handheld remote control transmitter used to activate a remote control deadbolt receiver, toggling the engagement of the deadbolt. After activation, an audible signal is produced by the receiver indicating the locked or unlocked state of the deadbolt. The unit is powered by a 3 volt lithium coin cell and has a single push-button for activation. Actuating the pushbutton signals the digital controller chip, a Microchip HCS361, to transmit an activation code block. The controller is configured to send a code via OOK, PWM modulation by turning on a biasing signal to the low power, single transistor Colpitts oscillator. Frequency stabilization is provided by a single port SAW resonator, placed in parallel with the base biasing circuit. The oscillator tank coil serves as an integral magnetic loop antenna minimizing grounding requirements. There are no provisions for external antennas or grounding connections. An indicator LED lights when the transmitter biasing is active indicating battery condition and operation. The code block sent is a bit-stream sent at approximately 2k bits per second modulated at 33% pulse width on for a digital 0 and 66% pulse width on for a digital 1 signal. The bit-stream contains a synchronization header and fixed and variable bit fields. The fixed bit field contains coding identifying the individual transmitter, while the variable field contains a coded sequence number, which can be incremented in a non-obvious manor. The combination of the proper ID code and a decoded sequence number which is after the last received sequence code number is interpreted by the receiver as a subsequent toggle request transmission. Transmissions of individual codes are less than 100ms long and are repeated at a 50% duty cycle as long as the pushbutton is activated for up to 20 seconds. If the pushbutton is released during the transmission of a code block, transmission of the block is completed. Each new transmission request causes the deadbolt activator to toggle the state of the deadbolt of the door on which it is installed.

BUTLER COMPANY FCC ID: SMK011260 REPORT #: M\Mr._Butler_Co\1686AT4\1686AT4TestReport.doc Page 2 of 10 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, INC. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a pre-selector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz. The ambient temperature of the UUT was 98.3ºF with a humidity of 40%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The UUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The UUT was placed in the center of the table. The table used for radiated measurements is capable of continuous rotation. The spectrum was scanned from 30 MHz to 10th harmonic of the fundamental. Peak readings were taken in three (3) orthogonal planes and the highest readings were converted to average readings based on the duration of "ON" time. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. Measurements were made by TIMCO ENGINEERING INC. at the registered open field test site located at 849 N.W.
