WARNING
UNINTENDED EQUIPMENT OPERATION OR LOSS OF CONTROL
• The cables connected to the GP should be secured by cable clamps to prevent weight or tension of the
cables added to the connectors or terminals.
• Be sure all cable connectors are securely attached to the GP unit. A loose connection may cause incor-
rect input or output signals.
• Do not press on the GP unit’s display with excessive force or with a hard object, since it can damage the
display. Also, do not press on the touch panel with a pointed object, such as the tip of a mechanical pencil
or a screwdriver, since doing so can damage the touch panel.
• Do not install the GP where the ambient temperature exceeds the specified range. Doing so may cause a
unit malfunction.
• To prevent abnormally high temperatures from occurring inside the GP, do not restrict or block the GP
unit's rear-face ventilation slots.
• Do not operate the GP in areas where large, sudden temperature changes can occur. These changes can
cause condensation to form inside the GP, possibly causing it to malfunction.
• Do not operate or store the GP in locations where it can be exposed to direct sunlight, high temperatures,
excessive dust, moisture or vibration.
• Do not operate or store the GP 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 GP unit's surface. Instead, use a
soft cloth moistened with a diluted neutral detergent.
• Do not use or store the GP in areas with direct sunlight, since the sun's ultraviolet rays may cause the
LCD's quality to deteriorate.
• Do not store the GP in an area where the temperature is lower than that recommended in the GP 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 GP in areas where
temperatures are within the GP unit's specifications.
• After turning OFF the GP, be sure to wait a few seconds before turning it ON again. The GP may not oper-
ate correctly if it is restarted too quickly.
Failure to follow these instructions will result in death or serious injury, or unintended equipment
damage.
