A friend of mine brought his psr1000 over for me to look at. It won't remember registrations once you turn it off. I used to see this on computers when the battery wore out. I took it apart but couldn't find any battery. Any ideas? Thanks in advance.

The keyboard only saves the last RGT used after switching off.
I keep all my Registrations on USB and just load as required.

That’s a 21 year old arranger. Things have progressed a bit since then!

Agree, surprised it even had registration saves

i had a psr1000. if i remember correctly , registrations have to be saved to disk . i put a usb emulator in mine and saved my registrations and songs all on one flash drive. but seem to remember that there is a user registration space in the keyboard of around 1.5 mb. i would check the manual online. could also be a processor or motherboard issue.

I set up 8 registrations (right hand voices) for my friend and it worked for years. He became ill and didn't use the 1000 for over a year. When he went back to it the registration voices were gone. He brought it to me to put them back in and it will work until you turn it off. When you power back up they are gone. For most of us this wouldn't be a problem but for my friend who is 80 and in poor health it is a big problem. I believe there is a battery or capacitor that keeps the memory when turned off.

I agree Tom. If you can get a Yamaha tech to share a factory SERVICE manual (not the Owners manual) there is probably a self-test to check the health of the battery, and maybe even instructions on how to change it. No doubt some disassembly will be required ;-)

Hi.
Most likely there is a tiny backupbattery at the motherboard, and sometimes they are soldered and not that easy to replace.
The Servicemanual is to find at PSR Tutorial too, hopefully it's OK to paste the link without any risk to be banned there or here:

I took a read of the service manual. I could have missed it, but I see no reference to any battery. Most likely a capacitor should keep enough charge on the memory to stop it dying, but has likely deteriorated over time.

As an alternative suggestion, maybe he could put a UPS on it (and any other music/computer gear he uses) in case of a power outage, and simply never turn it off?

It’s not like it draws much current, wouldn’t cost more than pennies a day to keep it switched on.

His main problem is, putting it in to a repair tech to sort the problem out might cost more than either finding another PSR1000, or even something FAR more modern and capable, with USB backup of the memory. Cheapest solution I can think of is simply to leave it on 24/7!

Gunner, Thanks for the link to the service manual. I went through the entire parts list and schematic and couldn't find any listed battery. The memory must be kept using a capacitor. Thanks for the help.

Diki, I was a repair tech for over 10 years but I've been out of it for 20 or more. That's why my friend brings it to me. I guess I can't fix this one. He plays at nursing homes with it. It should take him but a minute to put the 8 right hand voices into the reg buttons. Thanks for the input.

There's no hint of either a battery or a capacitor being used for data retention on the PSR1500/3000 - I have the service manual - nor do I recall seeing a battery inside my 3000 on the various occasions I had it apart (to replace the LCD, fix video out, change keyboard contact strips).

The internal memory is described as flash EPROM. If the 1000 is the same technology I'm afraid you could be in trouble.

There are two steps to saving a registration, the second step however is often overlooked. This process has not changed in decades for Yamaha arranger keyboards, regardless of the model.

Step 1: After setting all the information you wish to save on the main page, Press the MEMORY button, then press the registration button you wish to save it in. Be sure, however, to have the boxes ticked in the registration memory contents page that you wish to save.

Step 2: Once you have saved the individual registrations (1 through 8) you must now save the registration bank. Next, press the "J" button in the lower right corner of the display, then select SAVE. This will open the registration bank page. Now, you must name the registration bank in which the registrations are going to be stored. There are provisions for naming the bank at the bottom on the screen. After naming the bank where the registrations are stored, press OK and now there are permanently saved in the User Memory area of the keyboard. If you want to save this to your USB drive, you must tab to the USB1 after pressing the "J" button.

Now, Yamaha has not used a storage battery since the PSR-500 model became available. All the OS and saved user information has been stored on a chip since then, thus no battery needed.

Hope this helps, Tom, and others,

Gary

Hi Gary.
Not to twist the topic, but it's nice to see you're active again, or at least feel as good that you're in condition to peek in and write a post. 👍
Wish you the best Captain Sailor! 😊

Hi GJ, glad to be posting once in a while. As for the sailing, well, health issues forced me to sell the boat at giveaway price. I know that I am dying of a terminal lung disease, and I did not want to leave the burden of selling by sailing yacht to my wife and children upon my passing. Just a month prior to selling the boat, it was appraised for $31,700 USD. After listing it for nearly a year, I ended up sell it for just $5,000 USD, which was less than the cost of the onboard, navigation electronics and radar. The day I sold the boat, I damned near cried.



All the best,

Gary

Gary, even if you're not sailing at The Seven Seas as Cpt. at your own ship anymore, you're still sailing at the Sea of Life. ⛵
I know the feeling when you have to leave behind something you really love to do, but it's good medicine in remembering all the nice things you was doing while you did what you loved most.
Memories can be pure gold, so keep on sailing Cpt! ⚓ 👍
