Realtone SC-60 low battery display problem

[Katie Wasserman]

There's probably a resistor or two that sets the low battery threshold. But without a schematic it could be hard to find this. I would run the calculator off an external power supply -- removing the nicad cells -- and see at what voltage point the indicator turns off. If it doesn't turn off by the time you get to a reasonable voltage (1.5 x number of nicad cells) it's probably something more than just a resistor tweak that's needed to fix this.
