 P-1   Preparation for installationThis LCD has a temperature sensor and cooling fan. If the LCD  
becomes hot, the cooling fan will turn on automatically. If t he 
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 40). If  
the temperature is higher than the normal level, set “COOLIN G 
FAN” to ON using the SCREEN SAVER function (See page 40). 
To avoid the monitor from falling 
When installing the monitor using the tabletop stan ds (optional), 
take measures to prevent the monitor from falling over in cas e 
of an earthquake or other disaster to lessen the probability  of 
injury and damage resulting from the fall.
As shown in the  gure, secure the monitor to a solid wall or 
pillar using rope (commercially available) strong enough t o bear 
the weight of the monitor. [LDT323V: approximately  14.5 kg (with 
the optional stands)]
Use of screw hooks (with opening) is recommended.
360 mm
CAUTION: 
  The effect of the fall prevention substantially depends  on the strength of brackets and base to which the fall 
prevention devices is attached. When you cannot ensure 
suf cient strength, provide adequate reinforcement.
  Though the recommended fall prevention is intended to  lessen the probability of injury and damage, it doesn’t 
assure its effectiveness against any kind of earthquake or 
disaster.
  Do not sleep where the monitor may topple over or fall in  case of an earthquake or other disaster.
  Before moving the monitor, remove the rope that is  securing the monitor. Failure to do so may result in injury or 
breakdown of the monitor.

monitor when it was packaged, beneath the LCD monitor so as 
not to scratch the panel.
Ventilation requirements for enclosure mounting
To allow heat to disperse, leave space around the monitor as  
shown in the  gure below.
CAUTION: 
The upper limit of the operation guaranteed temperature ran ge 
is 40C. When installing the monitor in a case or an enclosure, 
ensure adequate ventilation to keep the temperature inside 
the case 40C or lower by providing a cooling fan or ventilati on 
holes in the case.
