Security against power failure
If the battery is used, the BEETLE /M system has another important
feature.
When the power fails, the system remains fully functional for a short
period of time. The power needed for further operation is supplied by
the battery.
Because operation is maintained with the aid of the battery, the
application program can be terminated correctly.
The power failure is reported to the application program by means of
the retail device interface (see chapter Software). The application
program then terminates the program correctly by, for example, closing
open files and writing important information to the non-volatile memory.
The termination of these actions is reported by means of the retail
device interface. This causes the system to be disconnected, which
also prevents the battery from being discharged unnecessarily.
Peripherals connected to the power output jack of the
POS system are not powered during a power failure.
