Do not allow water, liquids or metal fragments to enter inside the ST unit’s case, since they can cause
either a malfunction or an electric shock. The allowable pollution degree is 2.
Do not operate or store the ST in locations where it can be exposed to direct sunlight, high temperatures,
excessive dust, moisture or vibration.
Do not operate or store the ST 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 ST unit’s surface. Instead, use a
soft cloth moistened with a diluted neutral detergent.
Do not use or store the ST in areas with direct sunlight, since the sun’s ultraviolet rays may cause the
LCD’s quality to deteriorate.
Do not store the ST in an area where the temperature is lower than that recommended in the ST 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 ST in areas where
temperatures are within the ST unit’s specifications.
After turning OFF the ST, be sure to wait for 5 seconds before turning it ON again. The ST may not operate
correctly if it is restarted too quickly.
Due to the possibility of unexpected accidents, be sure to back up the ST unit’s data regularly.
