Well, I remember in some pager programs (i.e. advisor pro, advisor elite) that your device, scanner or pager, can since when battery starts getting low to give you the "low battery!" alert. By default, once the voltage reaches a low of 3.94 volts DC, that's when it alerts you for low battery. I'm just wondering what would happen if I were to set it lower. In pagers if you set it lower, they wouldn't alert you at all, they would just cut off due to lack of power.
