Precautions
■Value for monitoring time
Windows is determined to be frozen even when a service of this product cannot run because the load on Windows is high.
When temporarily operating a system under a high load, set a large value for the time to detect an error. If this function runs
even when setting the maximum value for the time to detect an error, adjust the system to shorten the high load time.
■Restarting Windows forcibly when an error occurs
If Windows is restarted forcibly without shutting down Windows, Windows may not start normally, data in a user drive may be
corrupted, or a file system error may occur. Ensure to create a backup for recovering Windows before restarting Windows
forcibly. (Page 99 Windows Recovery)
■Restarting Windows automatically when a system error occurs
If Windows automatic restart is enabled and also "Restart" is selected for "Windows Forced Restart," this product may restart
repeatedly. When selecting "Restart," disable Windows automatic restart.

■Starting Windows in the safe mode

If Windows starts in the safe mode, Windows is not forcibly restarted even when an error occurs.
■Lightning or flashing status of the OS LED
When selecting "Restart" for "Windows Forced Restart," the OS LED flashes because Windows attempts to restart even if the
Windows freezes or a system error occurs.

on Windows because Windows attempts to restart even if "Do Not Restart" is selected for "Windows Forced Restart" in CW
Configurator.
The OS LED turns OFF if Windows freezes or an system error occurs only when "Do Not Restart" is selected for "Windows
Forced Restart" in CW Configurator and the restart setting on Windows is set to not automatically restart.
