• To prevent the PL from overheating, be sure its air circula-
tion vents are clear and clean, and keep the unit's operation
area well-ventilated.
• Avoid operating or storing the PL near chemicals, or where
chemicals can come into contact with the unit.
• Before the PL is initially started, be sure to install its memory
(DIM) module. If this module is not installed, the unit will not
operate.
Notes on Handling the LCD
The FP's LCD contains a strong irritant. If the panel is ever cracked and the LCD's
liquid contacts your skin, be sure to wash it with running water for at least 15
minutes. If any of this liquid should enter your eye, be sure to flush your eye with
running water for more than 15 minutes, and see a doctor immediately.
The current brightness of the LCD screen will depend on the screen's current dis-
play and the LCD's contrast adjustment. Any brightness variations that result are
normal for LCD displays (i.e. dark and light points).
There are minute grid-points on the LCD surface. These points are not defects.
Occasionally crosstalk (shadows appearing on extended display lines) will appear
on the display. This phenomenon is a common attribute of LCDs and is not a
defect.
The displayed color will look different when viewed from an angle outside the
specified view angle. This is also normal.
Displaying a single screen image for long periods of time can cause an afterimage to
remain on the screen. To correct this, turn the unit OFF for 5 to 10 minutes, then
ON again. This phenomenon is a common attribute of the LCDs, and is not a
defect. To prevent this effect, you can:
- use the Display OFF feature; if the same image is to be displayed for a long
- change the screen display periodically to prevent the displaying of a single
image for a long period of time.
