WARNING
Children operating or playing with a garage door
opener can injure themselves and others. The garage
door could close and cause serious injury or death. Do
not allow children to operate the push buttons or the
remote control transmitters.
Install the receiver (and any additional push buttons)
out of the reach of children and away from all moving
parts of the door and door hardware, but where the
garage door is visible.
A moving garage door could injure someone under it.
Activate the opener only when the door is properly
adjusted, you can see it clearly, and there are no
obstructions to door travel.
To avoid electrocution, disconnect power to the garage
door opener before installing the receiver.
OPEN RECEIVER: Insert a small screwdriver in slot on
receiver front panel as shown. Twist up actuator cover.

until the receiver indicator light flashes, the receiver
will not learn the code.
