Safety Icons
This manual uses the two icons below to call attention to information important for the
safe and correct use of the PL. Please pay attention to these icons and follow all
instructions given by them.
The safety icons and their meanings are:
Indicates a potentially hazardous situation which could result in
serious injury or even death, if the instructions are not followed.
Indicates a potentially hazardous situation which could result in
minor injury or equipment damage if the instructions are not fol-
lowed.
Essential Safety Precautions
Be sure to follow the instructions given below to ensure the safe use of the PL.
To avoid a possiblity of electrical shock, be sure to connect
the power cord to the PL before connecting it to the main
power supply.
To avoid fires or electrical shocks, do not use voltages be-
yond the specified range.
Before opening the PL’s protective cover, be sure to turn the
unit’s power OFF. This is because the PL’s internal parts
carry high voltages.
To avoid fires or electrical hazards, do not modify the prod-
uct in any way.

PL-5700 Series User’s Manual
Preface
Before replacing the 100V unit’s backlight, be sure to turn
the unit’s power OFF to avoid electrical shocks. (Note: Do
NOT attempt to replace the 24V unit’s backlight)
Do not create touch panel switches that are used to either
control or to ensure the safety of equipment and personnel.
Mechanical switches, such as an emergency stop switch, a
deadman (two-handed) start switch, etc., must be installed
and operated via a separate system.
If metal particles, water or other types of liquids contact any
of the PL’s internal parts, immediately turn the unit’s power
OFF, unplug the power cord, and contact either your dealer
or Digital Electronics Corporation.
Read and understand Chapter 4 “Installation and Wiring”
thoroughly in order to select an appropriate installation loca-
tion for the PL.
Before either plugging in or unplugging a board or interface
connector, be sure to turn the PL’s power OFF.
To prevent a possible explosion, do not install the PL in ar-
eas containing flammable gases.
General Safety Precautions
Follow the instructions given below for correct and safe use of the PL.
• Do not push on the PL’s screen too strongly, with either your
finger or with a hard object. Excessive pressure can
scratch, crack or damage the screen.
•If the screen becomes dirty or smudged, moisten a soft cloth
with diluted neutral detergent, wring the cloth well, and wipe
the display. Do not use thinner or organic solvents.
• Do not use a pointed object, such as a mechanical pencil or
screwdriver, to press any of the touch panel’s switches,
since they can damage the display.
• Avoid exposing and operating the PL in direct sunlight, high
temperatures and humidity, and in areas where excessive
dust and vibration will occur.

4PL-5700 Series User’s Manual
Preface
• 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
period of time.
- change the screen display periodically to prevent the displaying of a single
image for a long period of time.

Be sure to check the specifications of any optional products used.
Also, if the temperature of the PL’s electrical cooling fins reaches 100 (+/- 15)
degrees, the PL’s saftety feature will automatically activate, turning the PL OFF.
Thus, since these fins are usually 25 degrees hotter than the surrounding
atmoshpere, once the area surrounding the PL reaches apporoximately 60 de-
grees, this safety feature will activate.
Once the temperature of these fins falls below 60 degrees, the unit can be re-
started and operation resumed.

2 Display Functions
Backlight life is designated as the number of hours until the brightness drops to half
of the maximum level, in a 25°C environment. Before leaving images on the display
for an extended period of time, turn the backlight off if at all possible.
For information about how to replace the backlight, see “7-2 Replacing the 100V
Unit’s Backlight.”
ll Display Colors
• Uneven brightness, flickering, or ghosts (caused by cross talk) may occur with the
PL-5700S1, PL-5701S1, PL-5700L1, and PL-5701L1, depending on the display col-
ors (especially halftones) or color combinations used. This, however, is a basic char-
acteristic of this type of display, not a defect. Since this flickering can sometimes be
caused by the combination of display colors used, selecting other colors may improve
the display quality.
• The higher the contrast between the foreground and background colors is, the more
likely that crosstalk will occur. Either changing the color combination or decreasing
the contrast may help to reduce the amount of cross talk.
See “5-2, System Parameters.”

II For black-and-white displays : the PL-5700L1 and the PL-5701L1
• These displays normally use only black and white,
with grey tones being produced by making the dots
flash. This display method, however, may cause flick-
ering to occur with certain halftones.
• If VGA 16-color standard pallet colors are used on a
black-and-white display, brightness will increase in
order of the pallet numbers, i.e. from 0 (black) to 15
(white). It is not recommended to use those colors
marked with asterisks (*) (shown in the figure to the
right), since they often cause flickering.
• Pallet colors 2, 6, and 9 may be hard to identify on
the screen, since they have almost the same level of
brightness.
• Some combinations of colors may not be easy to iden-
tify. Whenever you are developing an application it
is recommended that you frequently test how your
program will appear on the PL.
• Black-and-white tiled displays often appear better
than multi-colored displays.
• If you wish to use halftones, be sure to check their
display quality during actual PL operation.
III STN color LCD displays: PL-5700S1 and PL-5701S1
• STN color LCDs use three primary colors - red, green, and blue - to display up to
8 different colors. Halftones are produced by making the dots used in these three
colors flash. This mechanism, however, may cause flickering with certain half-
tones.
• Tiled displays using only pure colors - black, red, green, blue, yellow, magenta,
cyan, and white (pallet numbers 0, 12, 10, 9, 14, 13, 11, and 15) - may appear
better than displays using different colors.
• If you wish to use halftones, be sure to check their display quality during actual
PL operation.
