Voltage inverter question, Low voltage cutoff cuts at 11.9v instead of 10.5. Can I fix this?

generally this is done with a pot in non microcontroller based equipment. If there is microcontroller, then it could be programmed to cut out, and indirectly by increasing the reference voltage you can bring down the cut off point. What is the power involved/ What is this equipment? Try and see whether you can identify what the whole thing is about. Electronics is vast, but many things are common in this electronics world. There will be a power supply, there will be a keyboard, display, motor, solenoid, relay and a host of other things, including a ROM or PROM etc. Solution depends on how mcuh you can understand and reveal.
