E-EQ-MX1RG-D MX1 Reference Guide
Chapter 7 Troubleshooting
Problem Determination Tips
Use the tips in this chapter as a guide. They include solutions to the simplest problems as well as
things to observe when trying to diagnose more serious problems.
Consider the following:
• 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 MX1 and any optional devices are
doing as well as what actions you took immediately before the problem occurred.
• Consider the simplest solution first. Ask yourself logical questions and consider
alternatives.
• Which part of the system is operating erratically? Keypad? Disk/Flash Drive? Barcode
Scanner? Radio? Display? Each produces different symptoms.
• What program and/or optional devices are you using?
• What appears on the screen? Do you see any messages or random characters? Look up
any messages in the documentation for your software, (e.g. DOS, etc.)
• Are any LEDs illuminated? Which ones?
• Do you hear any beeps? How many? Are they long or short?
• Is the MX1 making any unusual noises?
• 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 for
technical assistance.
• Make sure you are operating under the specified environmental conditions discussed in
Chapter 3, “Power Supply”, and Appendix B, “Technical Specifications”, subsection
“Environmental Specifications”.
Use the troubleshooting procedures that follow these tips and, if necessary, perform any
diagnostic procedures that may apply. LXE technical help telephone numbers and contact
