Check Voltages and Temperatures
To check the battery voltage and processor temperature, enter
Configuration mode and select Terminal Settings>System
Information>Terminal Information.
•
The battery voltage must be at least 2.75V DC. Replace the
battery if the voltage is less than 2.75V DC.
•
The CPU temperature should be less than 95 °C.
To check the display temperature, select Terminal Settings>
Display>Display Temperature.
•
The display temperature should be less than 55 °C (131 °F).
If the CPU and display temperatures are higher, check for obstructed
airflow in the chassis and attempt to moderate the ambient
temperatures within the enclosure and surroundings.
Check the System Event Log
To check the system event log for errors or unexpected reboots, enter
Configuration mode and select Terminal Settings>System Event Log.
Perform Extended Diagnostics
To perform more extensive hardware testing on the 1000 terminal at
startup, enter Configuration mode and select Terminal Settings>Startup
Tests>Select Tests.
Select one or more tests to run. Enable extended diagnostics and set
the iteration or repeat count. Restart the terminal. The serial port test
requires a loopback connector with these connections.
Extended diagnostics are performed at every startup until disabled. A
failure will momentarily halt startup and display an error message.
