LCD Panel Usage Precautions
• The LCD panel’s liquid contains an irritant. If the panel is damaged and any of this liquid contacts your skin,
immediately rinse the area with running water for at least 15 minutes. If the liquid gets in your eyes, immediately rinse
your eyes with running water for at least 15 minutes and consult a doctor.
• The PS-A unit’s LCD screen may flicker or show unevenness in the brightness of certain images or at some contrast
settings. This is an LCD characteristic and not a product defect.
• Some LCD screens may have differences in brightness and tone. Please be aware of this difference when using multi-
ple units side by side.
• Depending on the ambient temperature, LCD screens may sometimes look whitish (at high temperatures) or blackish
(at low temperatures). This is an LCD characteristic and not a product defect.
• Some of PS-A unit’s LCD screens may contain black and white colored pixels. This is an LCD characteristic and not a
product defect.
• Extended shadows, or “Crosstalk” may appear on the LCD screen. This is an LCD characteristic and not a product defect.
• The color displayed on the PS-A unit’s LCD screen may appear different when seen from outside the specified viewing
angle. This is an LCD characteristic and not a product defect.
• When the same image is displayed on the PS-A unit’s screen for a long period, an afterimage may appear when the
image is changed. If this happens, turn off the PS-A, wait 10 seconds and then restart the unit. This is an LCD
characteristic and not a product defect.
• To prevent an afterimage:
• Set the PS-A unit’s display OFF feature when you plan to display the same screen image for a long period of time.
• Change the screen image periodically and try to not display the same image for a long period of time.
Do not operate or store the PS-A where chemicals evaporate, or where chemicals are present in the air.
Corrosive chemicals : Acids, alkalines, liquids containing salt
Flammable chemicals : Organic Solvents
Do not use paint thinner or organic solvents to remove dirt or oil from the PS-A unit’s surface. Instead, use
a soft cloth moistened with a diluted neutral detergent.
Do not use or store the PS-A in areas with direct sunlight, since the sun’s ultraviolet rays may cause the
LCD’s quality to deteriorate.
Do not store the PS-A in an area where the temperature is lower than that recommended in the PS-A
unit’s specifications. Doing so may cause the LCD display’s liquid to congeal, which can damage the LCD.
Also, if the storage area’s temperature becomes higher than the specified level, the LCD’s liquid may
become isotropic, causing irreversible damage to the LCD. Therefore, only store the PS-A in areas where
temperatures are within the PS-A unit’s specifications.
After turning OFF the PS-A, be sure to wait a few seconds before turning it ON again. The PS-A may not
operate correctly if it is restarted too quickly.
Due to the possibility of unexpected accidents, be sure to back up the PS-A unit’s data regularly.
