About the PL unit's Display Panel
• The PL unit's currently displayed data, its voltage and brightness setting each affect
the intensity of
Contouring
. (i.e., when some parts of the screen are brighter than
others, creating a wavelike pattern)
• There are minute grid-points (dark and light) on the Display Panel surface. This is part
of the PL unit's design and not a defect.
• Shadows may appear at the top of the LCD. This is normal for an LCD display.
• Sometimes the display area may look as if the display colors have changed.
This is a common attribute of LCD displays and is not a defect.
• Displaying a single image for long periods can cause an afterimage to remain when the
display is changed to another screen. To prevent this, periodically turn the PL OFF
and then ON again to remove this afterimage.
• Since the PL unit’s hard disk drive (HDD) is a consum-
able item, i.e. it has a finite lifetime, be sure to back up its
data regularly and prepare a spare HDD unit.
• To prevent file data damage, be sure to shut down the
PL unit’s OS before turning OFF the main power.
• After turning OFF the PL unit's power, be sure to wait
until the internal HDD stops spinning before turning the
power ON again (approx. 5 seconds).
• Do not turn PL unit's power OFF while the HDD is operating.
