Craftsman 520-1LM - Manual

TM

Universal Radio Control

OWNERS MANUAL

Transformer Model 85 may be required if your
garage door opener is a brand other than Lift-Master,
Chamberlain or Sears.

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).

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 A COMMERCIAL OPENER

Fully extend antenna wire below bottom of case as shown.

Loosen the three terminal screws on the receiver
(labeled 1, 2 and 3). Insert one end of a mounting clip
under each terminal. Make sure the clips are positioned
to clear the receiver flange, as shown.

Do not retighten

at this time.

Loosen the three terminal screws on the opener used for
push button controls and radio power.

Leaving the push button bell wire in place, insert the
other ends of the mounting clips under the opener
terminal screws.

NOTE: 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.
Retighten the terminal screws on opener and receiver.
Reconnect power to the opener. The receiver push bar
should light. If it does not, use Transformer Model 85.

MOUNTING ON RESIDENTIAL OPENERS

Use a 2 wire connection

only. Attach mounting clips

to 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.
