OLS flashes then release.

watch starts counting when the door stops moving.)

activated by the Single Button Control (terminal 1) only. T wiring
mode allows the door to attempt to close only one time for safety
purposes.

CAR DEALER MODE

Feature: The car dealer mode uses the SBC (Single Button Control
input) to bring the door from a closed position to the programmed
Open Mid-Stop position and keep it at that location even with
multiple inputs.
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). Wiring type must be set to TS or T.
TO PROGRAM:
1. Start with the door in the closed position.
2. Turn the SELECTOR DIAL to PROG.
3. 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).
NOTE: To disable the Dealer Mode follow steps 2 and 3, then
press the MRT button and release. (The GREEN TIMER LED will
flash 3 times indicating that the Car Dealer Mode is off.)
