LT Series User Manual 11
Preface
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 LT where the ambient temperature can exceed the
allowed range. Doing so may cause the LT to malfunction or shorten its
operation life.
• Do NOT restrict or limit the LT unit’s naturally-occurring, rear-face ven-
tilation, and do NOT store or use the LT in overheated areas.
• Do NOT store or use the LT unit in areas where large, sudden tempera-
ture 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 LT unit’s outer casing, since they can cause either an LT malfunc-
tion or an electrical shock.
• Do NOT store or use the LT in direct sunlight, or in excessively dusty or
dirty environments.
• Do NOT store or use the LT in an environment where shaking or exces-
sive vibration can occur.
• Do NOT store or use the LT where chemicals (such as organic solvents
and acids) can evaporate, or in environments where chemicals and ac-
ids 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 LT.
• Do NOT store or operate the LCD 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
LT unit’s screen data regularly.
