Terminal Does Not Start
Properly This section provides general troubleshooting information to assist you when
trying to resolve problems during startup.
Check for Adequate Power
If a terminal does not receive adequate power, it can result in unpredictable
behavior. Refer to
DC Power Connections on page 28 for power requirements.
Check Indicators at Startup
When the terminal starts the FAULT and COMM indicators flash on and off,
then the COMM indicator flashes to signal progress during startup. When
startup is complete, the COMM indicator remains on, and is controlled by the
communication driver or application. The COMM indicator typically flashes
when communication is active.
The indicators are off if the terminal is not receiving power. Check the power
wiring and power supply.
If the indicators remain off, the power supply or logic board has failed. Check the
power wiring and power supply:
• If the power is not within range, replace the power supply.
• If the power is within range, replace the terminal.
Table 52 shows indicator states if the terminal powers on and stops during
startup.
Check Start-up Messages and Codes
Refer to Maintenance Operations on page 151 for a list of message states and
error codes that can appear on the splash screen during startup.
