NOTICE TO U. S. CONSUMERS:

made garage door opener was manufactured prior to or after April 1,
1982, please call 1-800-528-9131 before installing this universal radio
control.
CAUTION
With SECURITY✚, the code between the remote control and
the receiver changes with each use, accessing over 100 billion
new codes.
You can activate your opener with several SECURITY✚ remote
controls (with yellow indicator lights) utilizing up to 8 functions,
and one SECURITY✚ Keyless Entry.
Transformer Model 85 may be required if your garage door
opener is a brand other than Lift-Master, Chamberlain or
Sears.
NOTE: Model 335-2LM is factory pre-set with matching
receiver and remote control codes.
IMPORTANT: For maximum security and range, you must
disable the existing radio on your opener, otherwise it
could still activate your opener:
• If there is an external receiver, disconnect power to it.
• If it is an integrated receiver, either clip off the component
that feeds power to the receiver or remove the tuning slug
and antenna from the receiver section.
• If you have a Lift-Master, Sears or Chamberlain opener with a
“SMART” receiver, erase the old codes by holding down the
Smart button for 6 seconds until the indicator light turns off.
• If you have code switches, reset them to a random code
and deactivate the receiver by removing the tuning slug
and antenna.
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.
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 OPENER
Fully extend antenna wire below bottom of case as shown.
Loosen the two terminal screws on the receiver (labeled 1 and
2). Insert one end of a mounting clip under each terminal.
Do not retighten at this time.
Loosen the two terminal screws on the opener used for the
push button control.
Leaving the push button bell wire in place, insert the other ends
of the mounting clips under the opener terminal screws. If the
number sequence of opener terminals doesn't match the
receiver, turn the receiver around (so back is facing out) and
complete the connection.
NOTE: Terminals 1 and 2 on the receiver MUST be
connected to the push button terminals on the opener.
