STEP 2: INSTALL YOUR RECEIVER
A. The receiver was designed to be installed in a
variety of ways depending on the type of operator
and the application. If standard hook-up is not
desirable or possible, accessories such as three
wire adapter sets and transformer adapter kits
must be used.
B.
Standard hook-up to three terminal operators: For
direct connection loosen the three screws on the
operator and slide the brass terminals under these
screws.
See Fig. 4.
Replace the pushbutton
wiring and tighten the screws. Be certain the
antenna wire is hanging down vertically and the
receiver terminal numbers printed on the receiver
case match the numbers on the operator terminal
strip.
