5. Troubleshooting
5.1 Calling Black Box
If your G.703 Adapter or Balun Mate II seems to be
malfunctioning, do not attempt to alter or repair it. It
contains no user-serviceable parts. Call Black Box
Technical Support at 724-746-5500; the problem might
be solvable over the phone.
Before you call, make a record of the history of the
problem. We will be able to provide more efficient and
accurate assistance if you have a complete description,
including:
• the nature and duration of the problem;
• when the problem occurs;
• the components involved in the problem;
• any particular application that, when used,
appears to create the problem or make it worse;
and
• the results of any testing you might have already
done.
