Do I need a jumper cable?

I’m following the instructions, but I don’t have a “trans” screw. Do I need to use the jumper for this configuration?

Hi @refurbmike. If you have a Doorbell Wired, you would use the Jumper Cable between the two terminals you have. One of those wires will go to your transformer, the other on goes to your Doorbell. I hope this helps.
