my LS9 has been doing some unexpected things with the scene memory, things changing unexpectedly. I'm wondering if this could be caused by a weak backup battery?

I don't have a desk available easily but I seem to remember something in the setup area that gave status of the battery. I don't know how old mine is but I did change the battery a few years back.

The battery will only affect whether the console settings will be retained when powering down. Once the console is powered and running, the battery does nothing.
What unexpected things specifically are happening?

Here is the key to getting help on internet forums. There is little point in saying your console is doing strange things, you need to describe what is actually happening.

it's doing some unexpected things with the scene memory. It's hard to describe, it retains some settings, not others, changes to name of scenes, erratic behavior only in the saved scene settings. The kind of abnormal behavior I would think would be due to the battery being low. The only problem is with saved scenes.

So it does what? "...retains some settings, not others..." so what settings, are are they the errors the same in all instances of corruption, i.e. saved EQ settings are recalled as: a) wacky random values; b) flat; c) unchanged from the previous scene ; d) all or none of the above. Are the items corrupted always the same, EQ or mix sends or DCA assignment, etc?
"...changes to names of scenes..." Eh? Scenes have numbers. Both alpha fields are essentially for human use/comments. So what happens, random characters? Scrambled field of original characters? Blank?
What happens if you save a fresh file (not previously saved to the desk) to a USB stick and then bring it up Studio Manager? If the USB save is good, will it load correctly to the desk if the desk's file becomes corrupted?
Or are there other things involved?

I haven't gotten that far along with the diagnosis. I was just wondering if possibly someone else had had similar problems when the battery started running down

You can do a battery check when you boot up. Hold down the "store" (IIRC) button while power up. Battery check is one of the choices along with fader calibration.

On most Yamaha console it also shows up in one of the preference screens. "it's doing some unexpected things with the scene memory.

The kind of abnormal behavior I would think would be due to the battery being low.

What did you do, and what did the console do?

I as said, you should change your thinking. This is NOT the sort of thing that happens when a battery gets low.

David, I know you aren't a novice so pardon me if this sounds accusatory, but have you checked those particular settings to see if they were flagged as SAFE? Just a thought...

I haven't checked anything out yet, just what I saw at the last show. Hopefully I can get the mixer out later today and see what's up in the light of day. We've had a cold spell here in Texas that we are not used to, so I haven't done anything yet. I was hoping someone had had a similar problem and that would give me a direction. I have received several directions from the comments here, and will check all of those things out when I get into it. I don't have a warehouse to work in, so I am at the mercy of mother nature. I only use my truck for sound work, so it stays loaded between shows. I have to unload the entire truck to get back to the mixer, as it goes in first. the first thing I'll do is turn it on and see if the restart gets me back to where I want to be, maybe I inadvertently, in the dark club, pushed a button by mistake and went to a screen I did not recognize. I saw about 6 scenes all with the same name, and that was not how it is supposed to be. At a previous show I opened a scene I commonly used and it had changed. So evidently at the show before that I saved something improperly, or did the mixer malfunction? That is the question I have not yet been able to answer.

Okay, looks like operator error. Powered up the mixer in a less hostile environment and all the scenes came up unchanged, except a couple of titles were wrong. Still not sure how I did that. Battery was ok. My saved scenes are my lifeblood, because most of the places I set up don't allow much of a sound check. I need to dedicate a usb stick to saving my scenes and keep it onhand. thanks to everyone that contributed.

one night I was mixing from my ipad, and noticed the scene had a different name on the ipad and on the mixer. I never changed scenes from my ipad, always at the mixer. Not sure how that happened. That was one of the scenes whose name had changed.
