Symptom Action

The monitor has screen jitter, or

the screen image is wavy,

unreadable, rolling, or distorted.

1. If the monitor self-tests show the monitor is working correctly, consider the

location of the monitor. Magnetic fields around other devices (such as

transformers, appliances, fluorescent lights, and other monitors) can cause

screen jitter or wavy, unreadable, rolling, or distorted screen images. If this

happens, turn off the monitor.

Attention: Moving a color monitor while it is turned on might cause screen

discoloration.

Move the device and the monitor at least 305 mm (12 in.) apart, and turn on

the monitor.

Notes:

a. To prevent diskette drive read/write errors, make sure that the distance

between the monitor and any external diskette drive is at least 76 mm (3

in.).

a. Monitor cable

b. Remote Supervisor Adapter II SlimLine (if one is present)
