Chapter 6 Troubleshoot the System
Interpret the LED Indicators at Startup
The PanelView 800 terminals have indicators to isolate operating problems.
They can be seen through the battery cover on the back of the unit.
•
Comm indicator for communication
•
Fault indicator for hardware faults
At startup, the Fault indicator is off, except for a few brief flashes, and the
Comm indicator is on. If the indicators remain off, check the power cable.
After a successful startup, both indicators are off and controlled by the
application running on the terminal.
The table shows indicator states if the terminal stops during startup.
Returning to the Out-of-box
Condition
You may want to return a terminal to the out-of-box condition to refresh the
terminal or to recover from severe application misbehavior. There is a special
maintenance action that permits you to perform a complete reset and return
to the out-of-box condition for the terminal.
Returning a terminal to an out-of-box condition does not affect the terminal
firmware revision or the installed font image.
Follow these steps to return your terminal to the out-of-box condition.
1. Connect an external USB keyboard to the terminal and hold the Ctrl and
Shift keys simultaneously, while starting up the terminal.
A dialog box appears with the prompt:
Return to Out of Box Condition?
2. Press Yes or F1 to return to the out-of-box condition, or press No or F2 to
cancel.
If you choose to return to the out-of-box condition, the terminal resets.
On the subsequent boot, the file system is formatted and removes the
contents including applications, logs, recipes, user-installed fonts,
