Operator Maintenance

In Case of Power Failure

When power is lost, the POS terminal retains its memory contents and all information on sales totals.
• When power failure is encountered in the POS terminal idle state or during an entry, the POS terminal
returns to the normal state of operation after power recovery.

Before Calling for Service

The malfunctions shown on the left-hand column below, labeled "Fault," does not necessarily indicate
functional faults of the machine. It is therefore advisable to refer to the "Checking" shown on the right-hand
column before calling for service.
• The display does not illuminate.
• No receipt is issued.
• No journal paper is taken up.
• Printing is unusual.
Fault Checking
• Is power supplied to the electric outlet?
• Is the power cord plug out or loosely connected
to the electrical outlet?
• Is the power switch in the "ON" position?
• Are the brightness control and the contrast
control adjusted correctly?
• Is the terminal in screen-save mode?
• See the printer manual.
