Security÷ ® KeylessEntry System, and one accessory wall
control. If you purchase a new remote, or if you wish to
deactivate any remote, follow the instructions in the Programming
section.
Activateyour opener with any of the following:
• The Hand-Held Remote Control: Hold the large push button
down until the door starts to move.
• The Wall-Mounted Door Controh Hold the push button or bar
down until the door starts to move.
• The KeylessEntry (seeAccessories): If provided with your
garage door opener, it must be programmed before use. See
Programming.
