General Safety Precautions
•
Do NOT strike the touch panel with a hard or pointed object, or press
on the touch panel with too much force, since it may damage the touch
panel or the display.
•
Do NOT install the GLC where the ambient temperature can exceed the
allowed range. Doing so may cause the GLC to malfunction or shorten
its operation life.
•
Do NOT restrict or limit the GLC unit’s naturally-occurring, rear-face
ventilation, and do NOT store or use the GLC in overheated areas.
•
Do NOT store or use the GLC unit in areas where large, sudden tem-
perature changes can occur. These changes can cause condensation to
form inside the unit, which can cause possible unit malfunctions.
• Do NOT allow water, liquids, metals, or charged particles to enter inside
the GLC unit’s outer casing, since they can cause either a GLC malfunc-
tion or an electrical shock. The allowable pollution degree is 2.
•
Do NOT store or use the GLC in direct sunlight, or in excessively dusty
or dirty environments.
•
Do NOT store or use the GLC in an environment where shaking or ex-
cessive vibration can occur.
•
Do NOT store or use the GLC where chemicals (such as organic sol-
vents and acids) can evaporate, or in environments where chemicals
and acids 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 clean the GLC.
• Do NOT store or operate the LCD (Liquid Crystal Display) in areas that
receive direct sunlight, since the sun’s ultraviolet (UV) rays may cause
the quality of the LCD to deteriorate.
•
Storing this unit in areas at temperatures that are lower than is recom-
mended in this manual’s specifications may cause the LCD panel’s liq-
uid to congeal, which may damage the panel. Conversely, if the storage
area’s temperature becomes higher than the allowed level, the LCD
panel’s liquid will become isotropic, causing irreversible damage to the
LCD. Therefore, be sure to store the panel only in areas where tempera-
tures are within the ranges specified in this manual.
•
Due to the possibility of unexpected accidents, be sure to back up the
GLC unit’s screen data/logic program regularly.
