“Ensoniq SD-1 Music Production Synthesizer low battery voltage warning

When turning the unit on, it displays “Low Battery Voltage” warning message is showing up. After click “Continue” button the unit seems to perform normally. All keys work and I was able to change different setting and sounds. No cartridge. Some floppy disks for sounds. Did not test all disks Synthesizer and a power cable only. Cosmetically it’s in good condition. Does show some wears. I cleaned the keys and they look good although they do look little yellowish color. Not sure whether it’s discolored due to age or an original color. See photos.” Click here to visit listing on eBay
