provided as described below.
2. Attached to an inside wall of the garage with
connecting bell wire (not supplied), described on

position them at least 10 feet apart to prevent
electronic interference.

shown.

and 2. 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

Loosen the two opener terminal screws used for 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.
Retighten the terminal screws on the opener and
receiver. Reconnect power to the opener . T he
receiver push bar should light. If it doesn't light and
