+.. note::
+   - | In case of connection issues between Odoo and the payment terminal, force the payment by
+       clicking on :guilabel:`Force Done`, which allows you to validate the order.
+     | This option is only available after receiving an error message informing you that the
+       connection failed.
+   - The terminal must have at least a 10% battery level to use it.
