## What this means[​](#what-this-means "What this means के लिए सीधा लिंक")

The payment terminal did not finish pairing with WCPOS.

Retry pairing after checking the terminal settings, and include the trace ID when contacting the payment provider.

## What to do[​](#what-to-do "What to do के लिए सीधा लिंक")

A settings change is needed before this will work. Retry after making the change above; retrying without it will fail the same way.
