Turning on the Terminal
After the terminal is properly installed, turn it on by pressing the top half of
the terminal's power switch. Listen for an immediate beep indicating that it
has received power.
Whenever you turn the terminal on, it automatically runs a five-second
self-test. If the terminal has recently been on and the cathode ray tube (CRT)
is warm, the screen flashes several display patterns as the self-test runs.
If the terminal encounters a problem during the self-test, a beep sounds and
an error code appears in the bottom right-hand corner of the screen. You
can't operate the terminal if certain error message are shown; it may need to
be serviced by a qualified technician .
•
Note-If
you see an X or Y in the bottom right corner of the screen, see the
Troubleshooting chapter.
To reset the terminal so that it will rerun its self-test, press the SHIFT key,
CTRL key, and SETUP (F3) key simultaneously.
When the cursor is in the upper left corner of the screen, the terminal has
passed all of its tests and is ready for operation.
The next thing to appear on the screen is the message line. LINE, LOCL,
ECHO,
or
BLCK appear at the top left part of the screen. Later you may see
messages about the terminal (called terminal status messages) above the left
half of the line. Messages from the computer may appear above the right half
of the line.
