Fast repairs at low costsIf the PanelView Plus 400 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.
Battery voltage, as well as the display temperature, are indicative of other potential issues as well. Check the battery voltage and display temperature from the PanelView Plus 400 terminal desktop or from the FactoyTalk View ME station configuration mode. If the voltage is below 2.75 volts DC, consider replacing the battery. Obstructed airflow in the chassis can cause the CPU and/or display to overheat. If the CPU temperature is above 95 degrees Celsius or the display temperature is above 55 degrees Celsius, try to moderate the ambient temperatures.
If you continue have start-up issues, observe the splash screen for state messages and for the status or error codes.

Status indicators are located on the back of your PanelView 400 terminal. The COMM indicator is green and reflects communication. The FAULT indicator is red and reflects hardware faults. Upon startup, the fault indicator should be off and the comm indicator on. If the fault indicator flashes a few times at startup, this is not a concern. However, if both indicators are off you should check the power cable. See the table below to interpret the terminal's indicator status:
| Fault Indicator (RED) | Comm Indicator (GREEN) | Meaning and Action |
| Possibly Recoverable Error | ||
| Blinking | On | Windows CE Operating System failed or missing. Reload firmware. |
| Off | Most recent firmware download failure. Reload firmware. | |

If the PanelView Plus 400 display lacks a touch screen, you may not have a touch screen display. Check the label on the terminal and the part number of the unit to verify.
Please Note: When calibrating your touch screen, the process requires four (4) screen touches. If the touches are not satisfactory, more will be requested until calibration is successful. If the touch screen does not calibrate or continues to malfunction replace the PanelView Plus 400 terminal.

Examine the status indicators at the Ethernet connector. If the indicator is green, a communication link is on. If the indicator is an amber color and flashing, this indicates data activity. You should always ensure there is a good connection to the hub and uplink ports. Poor cable quality and crimping can inhibit the ethernet connection.
When in configuration mode select Terminal Settings> Networks and Communications > Network Connections > Network Adaptors. Check the DHCP. If this is enabled the device will attempt to connect to a valid IP address within seconds of startup. If it fails to acquire and IP address, the TCP/IP protocol will assign 169.254.xxx.xxx. If the DHCP is not enabled, verify the IP address specified does not conflict with another device on the network.
Other devices must not share the same hostname if they are on the same network. When in configuration mode, select Terminal Settings> Communications and Networks> Network Connections> Device Name.
The Ethernet issue may be caused by the other side of the connection.
