Subject: Re: [DW8000] Battery Question

Sounds like a dead battery to me - I had the same sort of problem with a Juno 60.

From what I remember, the standard advice is to replace the battery with a 3 volt lithium battery of the type that is used on PC motherboards. They are easier to find and they do not leak. Korg Polysixes are notorious for having a rechargeable battery that is prone to leaking. I'd guess the Poly 61 is the same. If you do replace it with a lithium battery, you need to put a diode in somewhere to prevent the new battery from recharging. You don't need to do this on a Juno 60 because Roland chose to use non-rechargeable batteries in the first place.

I just snipped out the old battery on my Juno 60 and soldered in a new one. A good bit of googling should find you photos for what to do for a Polysix, and you should be able to apply that to a Poly61.

I was given a Poly-61 in rather poor shape by my cousin, who nabbed a
beautiful PolySix for next to nothing. The Poly-61 is now usable,
though some of the parameter buttons are still flakey. I recently
moved it from home to school and lost about forty presets, all
original creations. As long as it is plugged in, my new presets
remain. Was my loss a result of a dead battery? If so, what type of
battery does it use?

While I'm posting, for the first time I might add, I suppose I will
ask about external storage as well. Is there any other way to store
patches externally other than on tape? Keep in mind I have a Poly-61
and not a Poly-61M. While I am aware that computers and synthesizers
used cassettes for storage, I never personally experienced their use.
Is there any special type of cassette recorder needed for storage?
Does it have to be specifically geared for data storage? Also, does
anyone have ideas on where one could be purchased? Thanks in advance.
