I managed to find the manual for the WF-803M via Google: https://images-na.ssl-images-amazon.com/images/I/815-1z4VyIL.pdf
I haven't been able to for the MA2500D. One of the things I'm looking for is the wall mount instructions. It should be similar/straightforward, though what threw me off is the sockets on the back of the unit point in opposite directions, and I wanted to mount it vertically. Hoping to find both the manual for future reference, and the mounting instructions.
