In Reply to: QS backup battery mystery? Help please posted by Audrey Lane on July 16, 2001 at 15:39:30:
: Hi all again and thanks for your help.. I have another question now, it's about QS backup batteries. I don't think it's in the manual but I have heard some things about needing to replace it after a few years or something?
: I have had my QS8 for some time and I am not knowledgeable when it comes to this so I'm wondering if anyone else has already had their battery empty out, and if so, how they got a new one and put it in?
: Also, is the battery drained quicker when the QS is on or off? I am a bit puzzled and have not been able to find answers anywhere, it boggles the mind! Please let me know!
: Thank you!

The battery backs up the RAM memory. That is, the preset banks are unaffected, only the user bank is. The battery is a lithium cell, the same kind that are used in computers to retain memory such as the date and time while the machine is turned off. RAM in modern synths uses very little power so not much drain is placed on these batteries. It should last up to 10 years under normal use, but I've heard of people getting longer life due to heavy use of the instrument. If you play alot and leave the synth on for extended periods of time you can expect at least 10 years from the battery. I have a synth that is 11yrs. old and have'nt had to change it yet. Remove cover and locate battery. Get the number off of it and right it down for future reference. If and when you need to replace it, they are available at almost any reputable electronics parts store. I doubt you'll find it at Circuit City or Best Buy but Radio Shack may have it. I go to a wholesale parts house. They usually cost $3.00 to $10.00 depending on the model and voltage.
