GP-477R/577R Series User's Manual
Preface
To Prevent Damage to the GP:
• Never strike the touch panel with a hard or heavy object, or push on the touch
panel with too much force, since it may damage the unit.
• If the GP is used in an environment that has temperatures in excess of the
allowed range, the GP may malfunction.
• Do not allow water, liquids, or metal particles to enter inside the GP's chassis,
since they can cause either a GP malfunction or an electrical shock.
• Avoid restricting the GP's naturally occuring ventilation, or storing or using the
GP in an environment that is too hot.
• Avoid using or storing the GP in direct sunlight, or in excessively dusty or dirty
environments.
• Because the GP is a precision instrument, do not store or use the GP where
powerful shocks or excessive vibration will occur.
• Do not store or use the GP where chemicals and acids evaporate, or where
chemicals and acids are dispersed into the air.
• Do not use paint thinner or organic solvents to clean the GP.
• After turning this unit OFF, be sure to wait a few seconds before turning it ON
again. If the unit is started too soon, it may not start up correctly.
Be sure to back up all screen data regularly.
About the GP's Display Panel
• The Display Panel contents and the Contrast Adjustment 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 / light ) on the Display Panel's surface. This
is part of the GP'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's 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 effect:
Set the unit to "Stand-by Mode", which turns the screen OFF automatically
when there is no input for a specified period of time.
Do not display any single screen for a long period of time. Try to always
change the screen display periodically.
