12. Reattach the communication module, if necessary, and tighten the four screws to a
torque of 0.58 N•m (5…7 lb•in).
Troubleshooting
If the terminal is not operating correctly, check the power, display settings, status indicators,
and review the system startup and error messages.
Check for Adequate Power
A terminal that does not receive adequate power could cause unpredictable behavior. Verify
the power requirements in the Specifications table.
Check Status Indicators
The terminal has two status indicators to isolate operating problems.
•
COMM indicator (green) for communication
•
FAULT indicator (red) for hardware faults
When the terminal starts, the fault indicator should be off, except for a few brief flashes, and
the comm indicator on. If the indicators remain off, the power supply or logic module has
failed. Check the power cable. If the power is not within range, replace the power supply. If
the power is within range, replace the logic module. After a successful startup, both indicators
are off and controlled by the application running on the terminal.
