The port to which the
terminal connects may
be faulty.
Try connecting the terminal to
another system. If this solution
works, the port to which the
terminal was connected is faulty.
If the terminal still does not
operate, it is faulty. In either
case, contact your Digital services
representative.
The terminal cable may
be faulty.
Connect the terminal cable and
the terminal to another system.
If the connected terminal works,
the DZ circuitry or MMJ connector
is faulty. Otherwise, the cable
is faulty. Contact your Digital
services representative.

contains question marks.
A diagnostic error has
occurred.
See Section 1.4.
The power-up test

Make sure the terminal settings
are correct, then run the power-
up test again. If the terminal is
set correctly, contact your Digital
services representative.

the operating system.
