Proface FP3900 - 19 Flat Panel" - Manual (Page 2)

To prevent this unit from malfunctioning:
• Do not strike the FP unit's touch panel with a hard or heavy object, or press on the
touch panel with too much force, since it may damage the display.
• Do not install the FP where the temperature will exceed the specified range.
• Be sure that water, liquids or metal particles do not enter the FP, since it may cause a
malfunction or a short circuit.
• Do not install the FP where sudden, large changes in temperature may occur. These
changes may cause condensation to form inside the unit, possibly leading to a mal-
function.
• To prevent excessive heat from building up inside the unit, do not install the FP where
its ventilation holes may be blocked. Also, do not install or store the FP near high
temperature equipment.
• Do not install or store the FP where direct sunlight or high levels of dust exist.
• Since the FP is a precision instrument, do not install or store it where either strong
shocks or excessive vibration may occur.
• Do not install or store the FP in an area containing chemicals or chemical fumes.
• Do not use paint thinner or organic solvents to clean the FP unit's case or screen.
• After turning the FP OFF, be sure to wait a few seconds before turning it ON again. If
the FP is started too soon, it may not start up correctly.
