Notes on the Main Power Switch

Automatic restart deals with cases when you accidentally unplugged the AC power cord
or unexpected power outages. By keeping the power flag ON, after the resumption of
power, the machine will start up automatically.
In rare cases, when you reconnect the AC power cord to a power outlet, the machine does not
start automatically. This is due to the timing of releasing the residual charge. If you press the main
power switch when the residual charge was already released, the power ON flag will not be set.
For such a case, start the machine manually by pressing the main power switch.
Shutdown Method
1. Press the main power switch [A] on the machine.
2. The shutdown message appears. After the shutdown process, the main power is
turned OFF automatically. The main power LED on the operation panel is turned OFF
when the machine completes the shutdown.

Before removing and adjusting electrical boards, do the following procedure.
Otherwise, the board can be damaged by the residual charge inside the machine
and must be replaced.
3. Disconnect the power cord after shutdown.
4. Press the main power switch for a second to remove the residual charge inside the
machine.
Forced Shutdown
In case normal shutdown does not complete for some reason, the machine has a forced shutdown
function.
To make a forced shutdown, press and hold the main power switch for 6 seconds.
In general, do not use the forced shutdown.

Forced shutdown may damage the hard disk and memory, and can cause damage to the
machine. Use a forced shutdown only if it is unavoidable.
