PROGRAMMING NOTICE: If this Security✚® door operator is operated with a non-rolling code transmitter, the technical measure in the receiver of the door operator, which provides security against code-theft devices, will be circumvented. The owner of the copyright in the door operator does not authorize the purchaser or supplier of the non-rolling code transmitter to circumvent that technical measure. To Add or Program a Hand-held Remote Control (Not Provided) Below are instructions for programming your operator to operate with optional Security✚® remote controls. A maximum of eight Security✚® remote controls can be programmed to work with your operator. USING THE "LEARN" BUTTON 1. Press and release the purple "learn" button on the motor unit. The learn indicator light will glow steadily for 30 seconds. 2. Within 30 seconds, press and hold the button on the hand-held remote* that you wish to operate your door. 3. Release the button when the learn indicator light blinks and shuts off upon learning the remote control. If the optional remote light is installed, the light will blink. 4. If the safety reversing sensors are not installed or misaligned, the door will not close from a hand-held remote control. If this occurs, the door can be closed by pressing and holding the push button on the single button control station until the door has closed. Releasing the push button prior to the door closing will cause the door to reverse. To Erase All Codes From Motor Unit Memory To deactivate any unwanted remote, first erase all codes: Press and hold the "learn" button on motor unit until the learn indicator light goes out (approximately 6-9 seconds). All previous codes are now erased. Reprogram each remote or keyless entry you wish to use. 19
