onnect two insulated wires (included) from the SC-1 to the spring
clips on the bascule bridge as shown in the diagram below. To con-
nect the wires to the spring clips, press down the springy upper half of
the metal loop until the lower part projects through the slot. Insert the
bare wire end into the loop, and release the upper part of the clip.
Spring tension will hold the wire tight. When all the connections have
been made, plug your SC-1’s wall pack into a standard outlet. To oper-
ate your bascule bridge using the SC-1, you must first assign it an acces-
sory number (refer to your SC-1 instruction manual).
After the number has been assigned, press AUX1 on your CAB-1
remote to activate the bascule bridge’s drive motor.
