If the garage door opener lights are fl ashing 5 times during
the steps for Program the Travel, the programming has
timed out. If the cable tension monitor is not installed or
is sensing too much slack in the cable, the garage door
opener light will fl ash 5 times. Ensure the cable tension
monitor is correctly installed then follow the steps for
Program the Travel. If the garage door opener lights are
fl ashing 10 times during the steps for Program the Travel,
the safety reversing sensors are misaligned or obstructed
(refer to page 12). When the sensors are aligned and
unobstructed, cycle the door through a complete up and
down cycle using the remote control or the UP and DOWN
buttons. Programming is complete. If you are unable
to operate the door up and down, repeat the steps for
Programming the Travel.
