WARNING:
DO NOT operate the garage door opener unless the
automatic reversal system is working correctly. Following
this rule will reduce the risk of death or serious personal
injury.
NOTICE:
This task requires the garage door opener to be
connected to a power source.
 Install and wire the indoor keypad as described earlier in
the Installation section.
 Connect the garage door opener to an AC power supply.
NOTE: Make sure the power supply is normal household
voltage, 120 volts, AC only, 60 Hz.
INSTALLATION
 Press and release the UP/DOWN button on the indoor
keypad to raise the garage door.
 Place a 1-1/2 in. board (approx. the size of a 2x4 laid flat)
on the garage floor beneath the door.
 Press and release the UP/DOWN button on the indoor
keypad to lower the garage door. When the door strikes
the board, it should reverse direction immediately.
 If the garage door reverses direction after contacting the
board, the reversal system is working properly and no
adjustments are needed.
 If the garage door stops before striking the board or
strikes the board and then stops, increase the travel limit
for the closed position and repeat the test.
 If the automatic reversal system continues to fail, contact
customer service or a qualified service person for
assistance.
