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 malfunction shown in the left-hand column below, labeled "Condition," does not necessarily indicate
functional faults of the terminal. The condition listed is only meant to be a reference for the items shown in
the "Checking" column at the right before calling for service.
Condition
The power indicator is not lit.
• Is power supplied to the electrical outlet?
• Is the AC power cord plug removed or loosely connected to
the electrical outlet?
• Is the AC adapter connector removed or loosely connected to
the AC adapter jack?
