Remind button

You can use the remind button on the light path diagnostics panel to put the system-error LED on the
operator information panel into Remind mode. When you press the remind button, you acknowledge the
error but indicate that you will not take immediate action. The system-error LED flashes while it is in Remind
mode and stays in Remind mode until one of the following conditions occurs:
• All known errors are corrected.
• The server is restarted.
• A new error occurs, causing the system-error LED to be lit again.
