Hi,

Does anyone know how the Xpander stores its settings?

If you turn it on and off, it keeps the settings, for years and years.
Is there a long-life battery?

Thanks for any explanations!

Cheers,

Jeremy.

There is a lithium battery that should be replaced every 10 year or so !
Some say it can start to leak and damage vital components if it get too old !

I've had the old (that is soldered on the board) replaced with a battery holder that uses the same type of lithium battery as a PC for easy replacment without soldering.

Hi Jeremy,

The RAM data ( patch/multi data ) in the M12/Xpander is battery backed. As 
opposed to FLASH ROM which is common in more modern designs. The only problem 
with battery backed RAM is you have to replace the battery every so often. It 
offers a theoretically endless number of re-writes ( Patch Saves) .

The Lithium battery used in the M12/ Xpander is one of the more durable and long
lasting batteries I have ever seen. 
I keep meaning to change mine but have not gotten around to it yet. It's been 
holding the patches fine since the late 1980's.

I have seen the same model battery leak once from a piece of test gear (not 
musical instrument) manufactured in 1981. It did not spill onto the board but 
developed some kind of white crystals around it's case. It still worked fine but
I replaced it anyway.

You can get exact replacements from Digi-Key which pretty much ships worldwide. 
And I happen to know they have a several European 
and far east distribution centers, if you need one right away.

Confirmed !

I still have the 1st battery in my Xpander,- since I buyed it new.
No leakage though,- and when I thought there\ufffds a replacement necessary, I\ufffdve found out the old is full up to now.
I\ufffdm sure it depends on usage of the Xpander/Matrix-12, if it\ufffds been switched on all day for a few hrs,- the battery holds your patches for decades.
