the solutions to these problems.
The display appears to be blank or very dim

Check to see if the power switch is in the on position, and the LED
Power indicator on the back of the PA PowerStation is lit.
a. If you have an STN display and the PA PowerStation is operating
properly, adjust the contrast on the display. See Adjusting the
Contrast on page 4-2.
b. If the PA PowerStation is not operating properly, restart the unit.

If the screen still appears to be blank or very dim, and the unit has
been in operation continuously for a long time, replace the backlight
bulb. Replacement backlight bulb kits are available through Parker for
the 10” and 15” models. You may not replace the backlight bulbs on
the 5”, 6”, and 8” models.

A PS/2 mouse doesn’t work (5”, 6”, 8”, and 10” units only)
Make sure that you are using a Microsoft PS/2 mouse, specifically an 802.3
Microsoft-compatible mouse. Some PS/2 style mice that claim to be
Microsoft compatible will not work correctly with the PA PowerStation. Do
not use a serial mouse with a serial-to-PS/2 port adapter.
A keyboard doesn’t work (5”, 6”, 8”, and 10” units only)
1
Check the keyboard. Make sure that you are using an AT or a PS/2
style keyboard, not an XT-style.
