Troubleshooting
General Tips • If a problem occurs while you're working, stop immediately. If you
continue, you may lose data and destroy problem-related information.
• Observe what is happening. Write down what the power supply,
workstation computer and other devices are doing as well as what
actions you took immediately before the problem occurred.
• What appears on the workstation monitor? Record or capture a screen
image of any messages that occur.
• Carefully read popup messages: they generally contain information that
gives a solution to the problem that occurs.
• What programs and/or optional devices are you using on the
workstation?
• See if you can cause the problem to occur again. This may help you
understand the source of the problem and will help you describe the
problem if you must call InterMetro Customer Service for technical
assistance.
• What LEDs on the Fuel Gauge are illuminated or flashing?
• Do you hear any beeps? How many? Are they long or short?
• Check the power supply fuses. Are they intact?
Problem Checks
The power supply switch is in the
“Extended Storage” position, but the
mobile workstation is still powered
up when I plug into AC. • The power supply switch is not an ON/OFF switch.
For normal operation, turn the switch to the “ON”
position. For long-term storage, unplug the power
supply from AC and put the switch in the “Extended
Storage” (OFF) position.
Low battery LED (“LOW”) is
flashing. • Battery charge is very low. Plug power supply into
AC immediately to charge the battery.
The top four LEDs and AC LED are
on but the CH LED is off. • The battery is fully charged. No further action
required. The unit workstation may be unplugged and
run normally on battery power.
