In case of power failure
If the power supply to the cash register is cut by a power failure or any other reason, simply wait for
power to be restored. The details of any ongoing transaction as well as all sales data in memory are
protected by the memory backup batteries.
• Power failure during a registration
The subtotal for items registered up to the power failure is retained in memory. You will be able to continue
with the registration when power is restored.
• Power failure during printing a read/reset report
The data already printed before the power failure is retained in memory. You will be able to issue a report when
power is restored.
• Power failure during printing of a receipt and the journal
Printing will resume after power is restored. A line that was being printed when the power failure occurred is
printed in full.
• Other
The power failure symbol is printed and any item that was being printed when the power failure occurred is
reprinted in full.
Important!
Once receipt/journal printing or printing of a report starts, it can be stopped only by interruption of
power to the cash register.
