P-1 Preparation for installation
When you use this monitor in the multiple screen configurations,
you can install up to three monitors vertically in the landscape
position or up to one monitor vertically in the portrait position.
If you install four or more monitors vertically in the landscape
position or two or more monitors vertically in the portrait
position, set COOLING FUN to ON using the SCREEN SAVER
in the CONFIGURATION1 menu so that the temperature around
the monitors does not exceed the upper limit of the operating
temperature.
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 down. 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 53). If
the temperature is higher than the normal level, set “COOLING
FAN” to ON using the SCREEN SAVER function (See page 49).
When mounting an OPS-compliant computer (commercially
available), turn on the cooling fan.
Determine the installation location
CAUTION:
DO NOT ATTEMPT TO INSTALL THE LCD MONITOR BY
YOURSELF.
Installing your LCD monitor must be done by a qualified
technician. Contact your dealer for more information.
CAUTION:
MOVING OR INSTALLING THE LCD MONITOR MUST BE
DONE BY TWO OR MORE PEOPLE.
Failure to follow this warning may result in injury if the LCD
monitor falls.
CAUTION:
Proper operation of the monitor is not guaranteed when it is
mounted upside down, face up, or face down.
IMPORTANT:
Lay the protective sheet, which was wrapped around the LCD
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 figure below.
CAUTION:
Don’t block the holes in the rear of the monitor shown in the
figure above. If they are blocked, heat accumulates inside the
monitor, causing breakdown. The upper limit of the operation-
guaranteed 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 position is 35˚C.
Don’t block these holes.
