4. Operation
Usual operation
You may either leave the power switch of the unit on (operation status) or turn it off each time when stopping
the connected system. You can choose either of the operation methods for your convenience. We recom-
mend turning off the power switch when you do not use connected devices for a long time.
The battery is charged when the AC input plug of the unit is connected to a wall outlet (commercial power).
End of Battery Mode
If a power failure lasts long, the battery discharges and power output from the unit stops. Shut down your
computer after performing appropriate procedure (for example, saving data) while the unit supplies power.
Reboot
If the battery discharges completely during a power failure, the unit stops. After recovery from the power
failure, the unit automatically restarts and supplies power. If you do not want to restart the connected devices,
turn OFF the power switch of either the unit or the connected devices while the power is out.
It is also possible to deactivate the auto restart by turning ON the auto restart setting (setting switch 2 ). (See
page 33.)
