FP-570-T User's Manual iii
Do not press the screen's touch surface too strongly with either your finger or a hard
object, since the touch surface may be damaged.
When the surface of the display screen becomes dirty or smudged, clean the display
with a cloth soaked in a neutral detergent. Do not use paint thinner or organic solvent.
Do not press on the touch panel's face with sharp objects, such as a mechanical
pencil or screwdriver, since it might damage the panel.
Avoid using or storing the FP in direct sunlight, excessively dusty or dirty
environments, or where chemicals or their vapors are present in the air.
Avoid restricting the FP's natural ventilation, or storing and using the FP in an
environment that will increase the FP's internal temperature.
Please avoid using the FP in areas where sudden, large changes in temperature may
occur. These changes can cause condensation to form inside the unit, possibly causing
an accident.
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 the 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 display
and the LCD's contrast adjustment. Any brightness variations that result are normal
for LCD displays.
There are minute grid-points on the LCD surface. These points are not defects.
Sometimes 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 speci-
fied view angle. This is also normal.
Displaying a single screen image for long periods of time can cause an afterimage to
remain. To correct this, turn the unit OFF for 5 or 10 minutes, then ON again. This
phenomenon is a common attribute of the LCDs, and 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.
