I apologize for the extremely delayed response but we still wanted to reply.
I am unable to attach a PDF version of the USPA-6800 owners manual. Here is the link this unit on our website. You will find this PDF under the "Manuals & Specifications" section. If you have a USPA-6800U, the owners manual can be found the same way.
