RTO1024 (RTO1000 series) oscilloscope clock backup battery type and location

[JohnG]

Hi folks,

I have just gotten my RTO1024 scope up and running again, thanks in a large part to this thread: https://www.eevblog.com/forum/testgear/rohde-schwarz-rto1024-upgrade/.

However, I have noticed that if I power down the scope and remove the AC power, the clock resets to 2006-12-31 23:00:00 plus a couple minutes for startup. At the moment, it's an inconvenience, but I would like to fix this if possible. Before I make the unlock tools and crack it open, does anyone know if this has a battery I can replace and where it is? I'm guessing it is on the PC module, but wanted to check before I make some removal tools (special thanks to @jjoonathan).

Yep, just a plain old CR2032 on the PC module.

Don't bother making tools, I found a procedure that works with standard screwdrivers: your goal is to use one screwdriver to "open" the hinge ("oil seal hooks" work great) and jam the second screwdriver into the opening to hold it open while you focus on the other one.

This gallery is from before I figured out the trick with plain screwdrivers but it shows the hinge mechanism from the back: https://photos.app.goo.gl/M3uLj5EZG8Zk7qXB7

Thank you! The photos and videos were extremely helpful. I couldn't do it with screwdrivers, but I made a couple keys with some small steel brackets, a hacksaw, and some filing. Took me two iterations and 30 minutes total.

It's working now, and I really appreciate the help.
