garage door opener is a brand other than Lift-Master,  
Chamberlain or Sears.  
WARNING  
NOTE: Models 520-1LM and 520-2LM are factory pre-  
set with matching receiver and remote control  
codes. If you purchase additional remote controls,  
the receiver may be programmed to match the new  
remote control code (up to 4 “smart” remotes and  
one Keyless Entry Transmitter).  
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.  
THE RECEIVER MAY BE INSTALLED IN ONE OF TWO  
WAYS:  
1. Mounted directly on the door opener with clips  
provided as shown on page one.  
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.  
2. Attached to an inside wall of the garage with connecting  
bell wire (not supplied) as shown on page two.  
When installing two or more receivers in a garage,  
position them at least 10 feet apart to prevent electronic  
interference.  
MOUNTING RECEIVER ON A COMMERCIAL OPENER  
Fully extend antenna wire below bottom of case as shown.
