panel power indicator should light.
5. Boot an operating system.
6. When a message is displayed on the monitor,

Initial Tests
To assess the monitor's operation, perform the color
bar test and the fill screen test. Both tests are
ROM-based.
Color Bar Test
The color bar test displays an array of colors in the
form of a bar graph. To display the color bars using a
Zenith Data Systems PC-compatible computer:
1. Press the
CTRL, AL T,
and
INS
keys in sequence,
hold them, and then release them.
2. After the Monitor prompt appears, type C and
then press
RETURN.
Color bars should now be
displayed.
Fill Screen Test
The ROM-based keyboard test can be used to set
the brightness, contrast, dimensions, focus, conver ­
gence, and other qualities of the display to comfort­
able levels. To perform the fill screen test using a
Zenith Data Systems PC-compatible computer:
1. Press the
CTRL, ALT,
and
INS
keys in sequence,
hold them, and then release them.
2. After the prompt appears on the monitor, type
TEST and press
RETURN.
3. Select the keyboard test by pressing the 2 key.
4. Press any displayable key to fill the screen with
that character. (The capital Z is a good charac ­
ter to display for assessing display characteris­
tics.)
