SAFETY INSTRUCTIONS (Continued)
 Use the basic software that we specify. Operation is not guaranteed if any
other basic software is used.
 Performing emergency shutdown (that is, unplugging the power cable from
the outlet or shutting off the circuit breaker without proper shutdown of the
OS) may cause the OS or applications not to work properly or may cause the
saved data to be corrupted. Never perform emergency shutdown unless you
must stop the system immediately due to some kind of error.
 Keep in mind that if the power supply is cut, the system may not be able to
recover automatically.
