In Case of Power Failure

When power is lost, the POS terminal retains its memory contents and all information on sales entries.

• When power failure is encountered in 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 in the left-hand column below, labeled “Fault,” do not necessarily indicate

functional faults of the machine. It is therefore advisable to refer to the “Checking” shown in the right-hand

column before calling for service.

Fault Checking

• The display does not illuminate. • 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?

• No receipt is issued. • See the printer manual.

• No journal paper is taken up.

• Printing is unusual.
