Clearing a machine lock up
If you make a mistake in operation, the cash register may lock up to avoid damage to programs and preset data.
Should it happens, you can use the following procedure to clear the lock up without losing any data.
1 Power off the register.
2 Insert the PGM key in the mode switch.
3 Press down f, and turn the mode switch to PGM mode.
4 The display shows ten Fs, then release f.
5 Press s. The display shows ten Fs and issue a receipt.
Important!
• If the register does not show ten Fs, never press s and call service representative.
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 on-going 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.
The memory protection battery is constantly charging and discharging as you switch the cash register on and off
during normal operations. This causes the capacity of the battery to decrease after approximately five years of
use.
Important !
• Remember a weak battery has the potential of losing valuable transaction data.
• A label on the back of the cash register shows the normal service period of the battery installed in
your cash register.
• Have the battery replaced by your dealer within the period noted on this label.
