operate with up to eight Security.I.® remote controls and one
Security-I - ® KeylessEntry System. If you purchase a new remote,
or if you wish to deactivate any remote, follow the instructions in
the Programming section.
Activate your opener with any of the following:
• Thehand-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.
