To Avoid Serious Property Damage or Damage to the System

About Power Outages

An instantaneous voltage sag caused by a power outage or lightening can potentially damage
the basic software, the application software, or data. As a countermeasure against
instantaneous voltage sag, the use of the system with a PC battery mounted is recommended.
If a power outage occurs, turn off the earth leakage breaker and the power switch to guard
against voltage surges that can occur when power is restored.
When power is restored, the system returns to the condition that existed before the power
outage. If the power outage occurred in the midst of evacuation, the system automatically
resumes evacuation. If the system was open to the atmosphere, that condition is maintained
as is.

On the Power Supply for the PC

If power is shut off during access to the hard disk or other memory devices, a PC malfunction
can occur and the data and software stored on them can be destroyed. When finished with
the current operation, be sure to perform PC termination operations and then turn off the
power switch for the PC.

On Data Backup

In some cases, a PC failure or malfunction can cause data corruption. To avoid such a
problem, periodically copy the contents of the hard disk to another hard disk, CD-ROM, a
magneto-optical disk, or other external storage devices. Such periodic copying is referred to
as a backup. For further details on this topic, see the instruction manual supplied with the
PC.

About Application Software

Other application software programs should not be installed on the PC associated with the
system. Such programs, beyond producing unexpected operation screens, can adversely
affect the system and cause the system to fail to operate properly.
