themselves or others. The garage door could close and cause
serious injury or death.
Install the door control (or any additional push buttons) out of the

door hardware, but where the garage door is visible. Do not allow
children to operate the push button(s) or the remote control
transmitter(s).
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.
For pre-wired installations,
not overtighten.
NOTE: The automatic light feature will become functional
6-1/2 minutes after power is restored.
