yamaha prs 740 battery replacement

by Dave Kittler
(Adams, Ma)

When the battery goes dead on the yamaha prs 740, does the keyboard lose its internal programming and sounds, and if so, once the battery is replaced, is the information available to reprogram the internal sounds?

740 battery replacement

HI DAVE,

THE SETTINGS REMAIN IN MEMORY WITH THE AID OF A CAPACITOR THAT IS CHARGED WHEN PLUGGED IN.
IF YOU LEAVE IT UNPLUGED FOR ABOUT A WEEK ALL
YOUR SETTINGS WILL BE RESET.

I GOT THIS INFO AT (EPINIONS.COM)

I NEVER HAD A PROBLEM BECAUSE I USE IT ALMOST
EVERY DAY AND IT'S ALWAYS PLUGED IN.


HOPE THIS HELPS YOU.

Yamaha psr740 floppy interface

Is the psr740 floppy interface IDE or ???

I've seen interface boards that require an IDE interface which allow SD cards to be used instead of a floppy. Having been able to do that at the church's CVP307 (because it has an USB interface) I realize how wonderful it would be to have the massive capacity of an SD card instead of a paltry floppy's capacity.

usb interface
by: Anonymous

You buy a usb interface for the PSR740 you take out the 3.5 drive and replace it with the usb drive,you then split the usb stick into 1.44 units and can then use the PSR with all your songs on one usb stick

If there was such a thing I'd buy it.
