Follow the steps below to set the limits. WARNING Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. · Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system. · NEVER use force adjustments to compensate for a binding or sticking garage door. · If one control (force or travel limits) is adjusted, the other control may also need adjustment. · After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high object (or 2x4 laid flat) on floor. CAUTION Figure 1 Black Button Indicator Light WARNING CAUTION Antenna Orange Button To program the travel limits: 1. Press and hold the black button until the yellow indicator light starts flashing slowly then release. Push and hold the black button until the door reaches the desired UP (open) position (Figure 2). Adjust the position of the door by using the black and orange buttons. Black moves the door UP (open) and orange moves the door DOWN (close). NOTE: Refer to previous page for correct door position for one-piece door. Press either the black or orange button before the door hits the floor. Adjust the desired DOWN (close) limit position using the black and orange buttons (Figure 4). Check to be sure the door is fully closed without applying excessive pressure on the rail (rail should not bow upwards and the belt should not sag or droop below the rail). NOTE: If neither the black or the orange button is pressed, the door will reverse off the floor and the DOWN travel limit will be set automatically. Figure 3 or To prevent damage to vehicles, be sure fully open door provides adequate clearance.
