# PAYMENT401: Terminal pairing incomplete

## What this means[​](#what-this-means "Collegamento diretto a What this means")

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 "Collegamento diretto a What to do")

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