Status 641 means the USPTO mailed a non-final Office Action identifying issues with your application. You typically have three months to respond with arguments, amendments, or evidence. Missing the deadline can abandon the application.

The examiner has identified that your trademark specimen appears to show temperature levels rather than a brand source, and you need to provide an acceptable substitute specimen or adjust your filing basis.
