Hi @bowaburd thanks for reaching out and welcome to the Seller Community!
Great question, you can unpair a previously connected reader from your device by following the below steps.
1. Forget the reader from your Bluetooth devices list by going to Settings > Bluetooth on your device, and selecting Forget on the reader. Be sure to check that the four numbers in your settings match your reader’s serial number (you can find this on the back of the reader).
2. Open your Square app and navigate to More > Settings > Hardware > Card Readers.
3. Locate the reader you wish to unpair and select it.
4. Then select Forget This Reader.
7. Select Connect a Reader and follow the prompts on the screen to pair a new reader.
These troubleshooting steps are a helpful resource to have on hand.
Let us know how you go after trying the above!
