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.

Power-On Self-Test Failures
Message	Code	State
Failed RAM	6C	Fatal
Stuck Key	31	Fatal
Stuck Touch	3A	Fatal

Firmware Installation/Loading
Message	Code	State
Load Firmware Image into RAM	1E	Update
Write Firmware Image into Flash	A5	Update
Complete & Successful Firmware Installation	OK	Update
Invalid or Missing Firmware Image	0A	Fatal
Firmware Image Validation (CRC/Format) Failure	1E	Fatal
Firmware Image Compatibility Failure	1F	Fatal
Firmware Write-to-Flash Error	A5	Fatal
Firmware Read-after-Write Verify	D2	Fatal

Common Status Codes
Message	Code	State
Operating System Start-Up	GO	Boot
Operating System Initialize	I1...J0	Init
Boot Loader Connects to PC via USB Device	0A	AutoTest
Boot Loader Jumps to Operating System	FF	AutoTest
Boot Loader Loads Firmware Image into RAM	E6	AutoTest
Application Registration and Initialize	N1...N3	Init
Application Load and Execute	N4...N6	Load

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.

Fault Indicator During Start Up
Fault Indicator (Red)	Comm Indicator (Green)	Meaning	Action
Possibly Recoverable
Blinking	On	Windows CE OS firmware failed/missing	Reload Firmware
Blinking	Off	Last firmware download failed	Reload Firmware
Blinking	Blinking	EBC boot loader firmware failed/missing	Reload Firmware
Fatal Errors
On	Off	Fatal hardware error	Replace Terminal
On	Blinking	Fatal display hardware error	Replace Terminal

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:

Connect the terminal to an external keyboard via the USB port.
Start up the terminal while holding down the Ctrl and Shift keys at the same time.
A dialogue box will pop-up reading "Return to Out of Box Condition?"
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.
