Lift-master 335-2LM User Manual

Universal Radio Control

OWNERS MANUAL

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.

Model 335-2LM Security✚

(With 2 Remote Controls)

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. 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.

WARNING

Disconnect power to the garage door opener before installing the receiver.

To comply with FCC/IC rules, adjustment or modification of receiver and/or transmitter is prohibited, except for changing the code setting and replacing the transmitter battery. THERE ARE NO USER SERVICEABLE PARTS.

NOTICE TO U. S. CONSUMERS:

Some states prohibit the service or repair of garage door openers which cannot be made to comply with the safety standards contained in UL 325 (1988 revision). In order to comply with both the letter and the spirit of these laws, this universal radio control should not be used with any Lift-Master®, Chamberlain®, or Sears Craftsman®garage door opener manufactured prior to April 1, 1982. To find out if your Chamberlainmade garage door opener was manufactured prior to or after April 1, 1982, please call 1-800-528-9131 before installing this universal radio control.

Retighten the terminal screws on the opener and receiver. Reconnect power to the opener. The receiver push bar should light. If it doesn’t light and your opener has a radio power terminal, use the third mounting clip to connect receiver terminal 3 to opener terminal 3.

If the receiver push bar still doesn’t light, you must use Transformer Model 85. NOTE: With the transformer, use a 2

wire connection ONLY. Attach mounting clips to the receiver terminals 1 and 2, and to the opener terminals used for push button controls. Plug the transformer into the receiver as shown, and into a 120 Volt outlet.

Side 2 contains wall mounting instructions and code setting instructions.
