HBW1337Touch Pad Transmitter

To comply with FCC/IC rules, adjustment or modification of receiver and/or transmitter is prohibited, except for changing the code setting and replacing the transmitter battery. THERE ARE NO OTHER USER SERVICEABLE PARTS. Installation Choose a convenient location for installation. It should be at eye level, reachable by the shortest person who will use it, and within sight of the door. For a one-piece door, use the optional location shown in the illustration (on the edge of the door jamb) to avoid injury as the door swings up and out. Test the reception of the Keyless Entry by operating your opener from the selected location. Change the location if necessary. Remove the battery compartment cover to access the bottom mounting hole: • Insert a small phillips screw driver into the small hole at the bottom of the cover and gently pull outward to loosen. • Slide the cover down to remove. Center the keypad at eye level against the selected location. Mark 4-1/4" up the centerline from the bottom and drill a 1/8" pilot hole. Install top mounting screw, allowing 1/8" to protrude above surface. Position keypad on screw head and adjust for snug fit. With cover open so bottom mounting hole is visible, use a punch to mark hole. Remove keypad and drill 1/8" pilot hole. Replace keypad and complete installation with bottom screw, using care to avoid cracking plastic housing. Do not overtighten. To replace the battery cover, insert the lip at the top and snap in place. Side two contains instructions for changing the personal entry password and setting a temporary password. Door Jamb Edge (Optional Location for 1-Piece Door) Keypad Door Jamb Face SECTIONAL DOOR ONLY KEYPAD MUST BE INSTALLED WITHIN SIGHT OF THE DOOR Exterior Front Wall 1-Piece or Sectional Door Typical Sectional Door Installation Setting the Personal Entry Password We recommend that you program your personal password now, before you install the Keyless Entry. Then you can test the reception at the mounting location before you proceed further. 1. Choose a 4-digit personal entry password using the numbers from 0 to 9 (a number can be used more than once, for example, 4,0, 4,1). 2. Press the four buttons for the password, then press and hold the Enter button. The indicator light on the door opener panel will blink. 3. Press and release the “Smart” (learn) button on the door opener panel. After the opener lights blink, release the Enter button. Test by pressing the the password, then press Enter. The door should begin to move. You may also program the Keyless Entry from a multifunction door control, as follows: 1. With the door closed,enter the four digit password desired, then press and hold Enter. 2. Press and hold the light button on the door control. 3. Press and hold the door control push bar. 4. After the opener lights blink, release all buttons.

This temporary password can be limited to a programmable number of hours or a programmable number of entries. Rolling Code:While your password remains constant until you change it, the code between the Keyless Entry and the receiver changes with each use, randomly accessing over 100 billion new codes. Operation: Opener activates when 4-digit password and Enter button is pressed. If wrong numbers are accidentally pressed, correction can be made immediately. The Enter button will transmit only the last four digits. The Keypad will blink for 15 seconds after the password is transmitted.

Kelkhoff Manager, Product Safety THEORY OF OPERATION AND CIRCUIT DESCRIPTION MODEL 41A5232-1 REMOTE TOUCHCODE TRANSMITTER (Please refer to enclosed schematic drawing: 195D1337A) The model 41A5232-1 transmitter uses a 4 digit number entered on a numeric keypad to determine the code that will be transmitted. The sequence of operation is to press 4 digits on the keypad, then press and hold the “ENTER” button (within 10 seconds of entering the last digit of the code) to operate the desired receiving device (usually a garage door opener). RF transmission begins when the “ENTER” button is pressed and continues until the button is released or 52 seconds elapses, whichever comes first. The transmitter consists of a low power RF oscillator (Q1 and related parts), a digital encoder (U1 and related parts), a voltage regulator (Q3 and related parts), and a keypad having buttons labeled “0” through “9” and “ENTER”. Operation is initiated by pressing any one of the buttons on the keypad. This turns on transistor Q4 through diodes D7, D8 or D9, which supplies current to zener diode D5. The voltage developed across D5 provides bias to the voltage regulator circuitry of Q3. The regulator applies 5V to the VCC input of U1 which causes the microprocessor to begin operation by truning on Q6 which acts to keep the voltage regulator on when the button is released. After 4 numeric buttons have been pressed, activation of the “ENTER” button will cause a digital PWM signal to appear at pin 17 of U1. This signal drives and modulates the RF oscillator. The RF oscillator is of the grounded base type. C1, C2, C11 and C12 and foil inductor, L1, set the oscillator’s center frequency to 433 MHz. R1-R3 establish DC bias conditions. L2 and L3 reduce harmonic output. In order to preserve battery life, U1 turns Q6 off when operation has ended. Turn-off occurs 20 seconds after the last RF transmission. LEDs, D1-D3 and D11-D13, provide back illumination to the keypad. 1. EXPOSITORY STATEMENT 2. THEORY OF OPERATION 3. SCHEMATIC 4. PHOTOGRAPHS 5. FCC LABEL DRAWING 6. OPERATING INSTRUCTIONS 7.

No emissions were detected in the forbidden bands below 1.0 GHz. Certified by: Barbara P. Kelkhoff Manager, Product Safety THEORY OF OPERATION AND CIRCUIT DESCRIPTION MODEL 41A5232-1 REMOTE TOUCHCODE TRANSMITTER (Please refer to enclosed schematic drawing: 195D1337A) The model 41A5232-1 transmitter uses a 4 digit number entered on a numeric keypad to determine the code that will be transmitted. The sequence of operation is to press 4 digits on the keypad, then press and hold the “ENTER” button (within 10 seconds of entering the last digit of the code) to operate the desired receiving device (usually a garage door opener). RF transmission begins when the “ENTER” button is pressed and continues until the button is released or 52 seconds elapses, whichever comes first. The transmitter consists of a low power RF oscillator (Q1 and related parts), a digital encoder (U1 and related parts), a voltage regulator (Q3 and related parts), and a keypad having buttons labeled “0” through “9” and “ENTER”. Operation is initiated by pressing any one of the buttons on the keypad. This turns on transistor Q4 through diodes D7, D8 or D9, which supplies current to zener diode D5. The voltage developed across D5 provides bias to the voltage regulator circuitry of Q3. The regulator applies 5V to the VCC input of U1 which causes the microprocessor to begin operation by truning on Q6 which acts to keep the voltage regulator on when the button is released. After 4 numeric buttons have been pressed, activation of the “ENTER” button will cause a digital PWM signal to appear at pin 17 of U1. This signal drives and modulates the RF oscillator. The RF oscillator is of the grounded base type. C1, C2, C11 and C12 and foil inductor, L1, set the oscillator’s center frequency to 433 MHz. R1-R3 establish DC bias conditions. L2 and L3 reduce harmonic output. In order to preserve battery life, U1 turns Q6 off when operation has ended. Turn-off occurs 20 seconds after the last RF transmission. LEDs, D1-D3 and D11-D13, provide back illumination to the keypad. 1. EXPOSITORY STATEMENT 2. THEORY OF OPERATION 3. SCHEMATIC 4. PHOTOGRAPHS 5. FCC LABEL DRAWING 6. OPERATING INSTRUCTIONS 7.
