Battery Hot Swap
PM451 provides the Battery Hot swap mode which allows you to replace the battery without turning
off the device. When the battery is removed from the device, the display turns off and the device
enters Hot Swap mode. In Hot swap mode, data is retained for a while. Once you replace the battery
to a new one and lock the Battery lock firmly, the device comes back to normal operation mode
without the booting process.
