CAUTION:
Don’t block the holes in the rear of the monitor shown in the
fi gure above. If they are blocked, heat accumulates inside the
monitor, causing breakdown. The upper limit of the operationguaranteed ambient temperature when the monitor is installed
in the landscape position is 40˚C. When installing the monitor
in a case or an enclosure, ensure adequate ventilation to keep
the temperature inside the case 40˚C or lower by providing
a cooling fan or ventilation holes in the case. The upper limit
when the monitor is in the portrait or face-up position is 35˚C.
This LCD has a temperature sensor and cooling fan. If the LCD
becomes hot, the cooling fan will turn on automatically. If the
LCD becomes overheated, the “Caution” menu will appear.
If the “Caution” menu appears, stop using the monitor and
allow it to cool. When the LCD monitor is used in an enclosure
or with protection on LCD surface, please check the inside
temperature of the monitor by “HEAT STATUS” (See page 56). If
the temperature is higher than the normal level, set “COOLING
FAN” to ON using the SCREEN SAVER function (See page 52).
To avoid the monitor from falling
When installing the monitor using the tabletop stands (option),
take measures to prevent the monitor from falling over in case
of an earthquake or other disaster to lessen the probability of
injury and damage resulting from the fall.
As shown in the fi gure, secure the monitor to a solid wall or
pillar using rope (commercially available) strong enough to bear
the weight of the monitor. [MDT551S: approximately 38.6 kg (with
the optional stands)]
