Safety Precautions (Continued)
Power plug
Warning
Be sure to plug and unplug the power cable by holding the plug. Pulling
the power cable may break the line inside the cable. Be sure to plug and
unplug the power cable with dry hands. If your hand is wet, you may get
an electric shock. Be sure that the plug is not dusty and insert the plug
into the outlet. Do not use a loose plug, which may cause a fire. If you are
not using the device for a long time (e.g., during a vacation), be sure to
unplug the power cable.

Do not use the device with a power supply voltage other than the one
specified. It may cause electric shock or a fire may occur.

other devices and operations.
