I need to replace the clock battery in my AFS-4500. There's a cover plate for what seemingly would be to access the coin cell battery, but the battery isn't accesseable by it. It looks like you have to remove and completely disassembly the entire unit to be able to access the battery. It's has to be easier than that, right?

I also have a slave display as a second screen. Is there a clock battery in that unit as well, or just the main 4500 screen?
