Electric Backdrop Support System Installation Method

Insert the expansion rod into the metal tube and tighten the knob to secure it. Repeat the same process on the other side. Hang the motor onto the hook. Attach the other side to the hook as well. Align the screw with the motor’s opening and insert it (no need to rotate). Plug in the power supply. While gently pressing against the other end of the motor, press the "up" button on the remote until the screw is fully threaded in. Detach one side of the motor and rotate it clockwise one full turn to interlock the motor with the expansion rod.
