Chamberlain 1200 - Manual (Page 33)

Children operating or playing with a garage
door opener can injure themselves or others.
The garage door could close and cause
serious injury or death. Do not allow children
to operate the door control(s) or remote
control transmitter(s).
A moving garage door could injure or kill
someone under it. Activate the opener only
when you can see the door clearly, it is free of
obstructions, and is properly adjusted.

lights on the panel will

Your garage door opener receiver and remote control
transmitter have been set at the factory to a matching
