How do I enter a device code on Square Terminal to pair it with POS software

[rob3000]

I received a device code (of type TERMINAL_API) in order to pair my Square Terminal with the POS software. The instructions seems to indicate that I enter the device code (which consists of six letters) on the Square Terminal on the login screen, perhaps using some option to choose to enter a device code.

The login screen I see does not appear to have a "device code" option and only has a numeric keypad (so I cannot enter the six letters). When I enter my PIN on this screen, it logs me into the Terminal. I cannot find anyplace in the Terminal UI to enter a device code.

So, how/where do I enter the device code to pair my Square Terminal with the (custom) POS software.

First, log out of the handheld terminal completely.  Settings--> logout.  You should now be on the login screen with the option to log in with your email/password or a device code.
