Benefit: Provides energy cost savings by limiting the door opening height. Requirements: This feature works in conjunction with the programmable Timer-To-Close feature. To enable this feature you must first connect a treadle, photoelectric sensor or loop detector accessory to the SBC input and must have at least one LiftMaster Monitored Entrapment Protection (LMEP) device installed (refer to page 20).

Push the TIMER button and release (Green Timer LED will be lit). 4. Push the MID button and release. This turns on the Car Dealer Mode. (The GREEN TIMER LED will flash 6 times indicating the Car Dealer Mode is turned on.) 5. Push the TIMER button and release. 6. Turn the SELECTOR DIAL to the desired wiring type (TS or T).
