LINEAR CORPORATION FCC ID: EF4 SHA24711 STATEMENT OF ATTESTATION Model: SR5909 Remote Control Transmitter FCC ID: EF4 SHA24711 The equipment under test is a low powered remote control transmitter used as a replacement for the Stanley SecureCode® retail garage door operators. It is designed to send remote control signals to a garage door receiver. No supervisory signals or low battery functions are provided by this transmitter. This equipment has been tested in accordance with the requirements contained in the appropriate Commission regulations. To the best of my knowledge, these tests were performed using measurement procedures consistent with industry or commission standards and demonstrate that the equipment complies with the appropriate standards. Each unit manufactured, imported or marketed, as defined in the Commission's regulations, will conform to the sample(s) tested within the variations that can be expected due to quantity production and testing on a statistical basis. I further certify that the necessary measurements were made by Linear Corporation, 2055 Corte Del Nogal, Carlsbad, California. 92009.

LINEAR CORPORATION FCC ID: EF4 SHA24711 FCC IDENTIFICATION LABEL Model: SR5909 Remote Control Transmitter Linear Corp. requests authority to use the label as depicted, in accord with Section 2.925(e) of the Commission's Rules, follows herein. LABEL FACSIMILE Manufactured & Distributed by Linear Corporation Model: SR5909 Frequency: 310 MHz Request for Authorization of Section 2.925(e) The device for which Linear seeks authority is small in size and does not lend itself to the placement of a label, with associated warnings and instructions, in accord with the FCC labeling requirements. For Linear to produce such a label, the type size would be too small as to be useful to purchasers of the device. Accordingly, Linear requests authority to place upon the device an identification label such as the one depicted herein identified as LABEL FACSIMILE. The additional information which is normally required to be included with the FCC Identification Number in accord with Part 15 of the Commission's Rules shall be located herein as portion of the draft manual attached hereto. Accordingly, in accord with Section 2.925(e) of the Commission's Rules and past Commission decisions, Linear hereby requests authority to label its devices in the manner described herein. The user instruction manual will have the full text of the FCC disclaimer printed in a prominent location as follows: This device complies with FCC Part 15 and Industry Canada Rules and Regulations. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received , including interference that may cause undesired operation.

LINEAR CORPORATION FCC ID: EF4 SHA24711 SPECIFICATIONS & FUNCTIONAL DESCRIPTION SR5909 - TRANSMITTER 1.0 DESCRIPTION The SR5909 is a Stanley garage door replacement, low-power hand held remote control device operating at a frequency of 310 MHz. The signal output is a binary- coded, pulse-position type A1D modulated transmission which has an information rate of approximately 1670 bits per second (bps). It is coded by SecureCode® formatted wireless data for the Stanley garage door operators. Actuating any of the three push buttons illuminates a light-emitting diode (LED) and activates the transmitter. Releasing the push-button immediately terminates transmission. Transmission time is limited to 20 seconds if button is held on. 2.0 FUNCTIONAL DESCRIPTION The push-button switches, S1-3, applies power to the unit and activates L.E.D. (D1). Digital encoding is a function of microprocessor, U1. An internally generated microcontroller clock runs at approximately 4MHz and creates the coding and timing sequence. There are over 4 billion (4 x 10^9) possible code combinations. Coding is done during manufacture and is not user accessible. The RF oscillator / output transistor Q1 functions as a tuned Colpitts power oscillator whose feedback is primarily determined by C3. The frequency of oscillation is controlled by variable capacitor C5. The inductive trace load E1 is configured on the circuit board as the principle-radiating element. Emitter resistor R7, in conjunction with the base bias resistors R5 and R6, regulates the power output of the oscillator. Because of the transmitter's small size, its radiation pattern is similar to that of an elementary dipole.

Date Regulatory Compliance Engineer LINEAR CORPORATION FCC ID: EF4 SHA24711 DURATION OF RF TRANSMISSIONS SR5909 REMOTE CONTROL TRANSMITTER This transmitter is manually activated. It is used only for remote control of a garage door operator. As such, it may be operated continuously by the user (FCC Rules 15.231(a)(4)). However, due to battery constraints and an accidental continuous activation causing interference to the system, the maximum manually activated transmission for a single press of a pushbutton is 20 seconds. When the push button is released the transmitter ceases transmitting immediately. FCC Rules 15.231 (a)(1) allows no longer than 5 seconds upon the release of a manually activated transmitter.
