BEFORE YOU CALL AE CUSTOMER SUPPORT

If you believe you are experiencing a problem with your MDXII unit, first refer to the
information in this section to help you troubleshoot problems. This section provides
1) troubleshooting checklists and 2) lists of messages or other indicators of problems with
suggested actions to take.
If this information does not provide an adequate solution or if your problem continues, please
refer to "AE Customer Support" on page 8-14 for information on how to contact a Customer
Support representative.

Troubleshooting Checklists

DANGER:
Operating and maintenance personnel must have the correct training before setting up,
maintaining, or troubleshooting high-energy electrical equipment. Potentially lethal
voltages may cause serious personal injury or damage to equipment. Ensure that proper
safety precautions are taken.

FIRST CHECK

DANGER:
RISK OF DEATH OR BODILY INJURY: disconnect all sources of input power and
wait a few minutes before working on this unit or anything connected to it. Internal
components may remain live for 1 min after the MDXII unit has been disconnected.
When you believe you are experiencing a problem with your MDXII unit, first check for
obvious signs of damage to the unit, cables, and connectors. If you see signs of damage, power
off the unit and call AE Customer Support (see page 8-14). If no obvious signs of damage are
evident, proceed with the following checks.

CHECKS WITH THE UNIT POWERED OFF

1. Turn off the unit's input power and wait a few minutes before touching the unit.
2. Ensure that the correct grounding wire is connected to the ground stud (see "Grounding"
on page 4-7).
