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,
