Accumulator batteries
The accumulator batteries bridge power failures, thus allowing controlled
termination of the POS program by means of the appropriate software
(see the section entitled “Security against power failure” on page GB - 47).
Battery-charging time after initial startup is approximately
8 hours. The accumulator batteries are only charged while
the system is switched on.
The following table provides an overview of the length of time for which
battery power is supplied to the BEETLE /XL in the event of a power
failure (when the accumulator batteries are fully charged).
A peripheral device connected to the power output socket
of the POS system is not supplied with power in the event
of a power failure.
