D550 battery replacement

[urgetoplay]

Anyone have to replace their battery? Mine went dead this week; I'd like to know which battery is used,is it soldered to the board or in a holder. How hard was it to replace....Thanks for your time.....

The battery is a lithium CR2032. You can't miss it: it looks like a shiny quarter. It is usually solder directly onto the PCB. Go to an electronics store and ask for for a CR2032 holder (really cheap). If I remember correctly, it's a 3-lead. Check the polarity of the battery before putting it in the holder. There is a + engraved on one side. It goes up, facing you. The - side goes into the holder.

Not hard to replace: just 3 solder joints. But you need to take off the PCB to work at ease.

If your battery died a week ago, chances are that all your patches are gone by now.

Hope that helps

It's not a big problem.

REMEMBER to save Your patches etc. Probably You'll lost all sounds.

Changing battery is not a big problem. Check how big diameter it has [probably 20 mm]. If You want to get longer life battery try to find one with bigger mAh

That's all. + goes up, - goes down

Thanks guys. I'm not as concerned about the patches, have them all backed up on the computer. I'll give it a go after the holidays.....Happy holidays guys.

D-50/D-550 uses a CR2032 battery. It's not soldered in; it's in a holder (yes, Roland got smart). Pop the cover, remove the battery, insert new battery, replace cover, done!

Thanks for the precision, I've totally forgotten it. (I do not change battery often... usually people prefer to do it themselves and then save time and some $).

Thanks Synthaolic to set things right on this

Glad I checked back, I was going to pull the D550 and put it into the needs work pile. Then Harass Stephane' into giving me a battery soldering lesson. Even practiced my begging routine ....Glad its all unneccessary. Thanks for all the help guys....Ron

Harass me???

I owe you more than you can imagine.

I'm currently working (among other things) to a collection of books that will be available on my website. Complete, not for engineers but for musicians, with picture and all. [Yeah, they will be foolproofed before hitting the site to avoidyou my grammatical error, typos and other bursts of insanity].

thanks all,
I just got a message on my d550 that the internal battery was low.
after more than 15 years! I hope my internal patches (factory) are still there.
Anyone know where I can get them back if they are gone.
I have one external card. anyone know where I might get others.
thnks, ray

You can get the factory patch sets from here: http://bobbyblues.recup.ch/roland_d-50/ ... banks.html

Scroll down to the PN-D50-00 soundbank. You can download the sysex file from there. Then use MIDI-OX or another utility to dump the patches into your D-550.

The additional Roland card banks are available there for download as well.
