[TenTec] Orion 565 Tuner battery?

[Sandor Wetsel]

There seems to be a fair amount of conflicting information on the internet regarding the Orion's (565) internal tuner memory battery. I am about to embark upon the adventure that is the v2 mod and main battery replacement in this partsOrion and I would rather have everything in front of me when I tear the front panel down so I only have to do it once. Is the battery a CR2032 or something else?  All of the pictures I have seen do not seem to have a button battery in them and I know it should be obvious when I pull the panel off but in the mean time where do I look? I want to thank Dan for the chance to see if I can get this Orion up and running.
