Troubleshoot your Component Terminal

Incorrect Start-Up

If the terminal is not starting up correctly always check for adequate power first. Inadequate power can cause a variety of unpredictable behavior. Simply verify the terminal's power requirement in the specifications table. It is also good practice to determine whether there have been any changes since the last startup. Determine what these are to see if they can be reversed.

If you continue have start-up issues, observe the splash screen for state messages and for the status or error codes. 

Please note: Power-on self-test errors are fatal and likely caused by failed hardware. If the fatal error occurred during firmware installation and loading the terminal is likely recoverable. In this case, try installing the correct firmware. 

Status Indicators

Power indicators are located on the front of the C400 terminal, they communicate the system status. The green LED indicator lets the operator know the system is running and the display is on, whereas the red LED indicator shows that the system is running but the display is in screen saver mode. 

There are also two indicators on the back of the terminal, which help the operator identify operating issues. The Green Comm indicator reflects communication issues while the red Fault indicator reflects hardware faults. The table below helps identify potential problems if the terminal fails during startup. 

Reload Factory Settings

Returning the terminal to out-of-the-box condition can help the system recover from application misbehavior. This procedure will also restore your terminal if you have set terminal security and forgotten your password.

Re-Set Process:

1. Connect the terminal to an external keyboard via the USB port.
2. Start up the terminal while holding down the Ctrl and Shift keys at the same time.
3. A dialogue box will pop-up reading "Return to Out of Box Condition?"
4. Either select "Yes" or press F1 to return to the original settings, or press "No" or F2 to cancel.

About Reloading Factory Settings

If the terminal does not recognize the keyboard, simply restart the terminal and wait for the boot screen to display code N1 and repeat step 2. You will know that the keyboard has not been recognized if the terminal boots normally, displaying the configuration screen or startup application. 

When you return the terminal to its factory settings or out-of-box condition, the current firmware will remain on the terminal. This is the case whether or not you have upgraded the firmware. 

When the terminal resets the file system is formatted and removes applications, logs, user-installed fonts, objects, graphics, and recipes. Additionally, terminal configuration parameters return to their default settings.
