Notes:
●
Only use forced shutdown as an emergency operation when key,
mouse, and keyboard operations fail. A fault may have
occurred if the power cannot be turned off even by pressing the
Power switch for 4 or more seconds. Unplug the power cord
from the power outlet and contact your Anritsu Service and
Sales Office or agent.
●
Unplugging the power plug while the hard disk is being
accessed may cause failure of the hard disk. Unplug the power
plug when the power is off.
