thegarage door.

with the board.
If the door stops but does not reverse:

2. Repeat the Safety Reversal test.
If the test continues to fail, call a trained door systems technician.
4 - Test the Protector System

Without a properly installed safety reversing sensor, persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.
1 Open the door. Place an obstruction in the path of thedoor.
2 Press the remote control push button to close the door. The door will not move more than an inch (2.5

are no more than 6 inches [15 cm] above the floor), call for a trained door systems technician.
