Troubleshooting

Monitor Troubleshooting

Generally, if the monitor is out of focus, too bright, or too dark, adjust the
monitor’s brightness and contrast knobs. Each monitor model has its own set
of controls. Check the monitor operating booklet for more information about
your monitor.

Base Troubleshooting

A flashing power indicator indicates there is a hardware problem in the base.

If you find you must return a base for repair, send it in the same configuration
as when it failed.
