P-1 Preparation for installation

Determine the installation location

CAUTION:

DO NOT ATTEMPT TO INSTALL THE LCD MONITOR BY
YOURSELF.
Installing your LCD monitor must be done by a qualifi ed
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 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 fi gure below.

Wall

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 57). If
the temperature is higher than the normal level, set “COOLING
FAN” to ON using the SCREEN SAVER function (See page 53).
When mounting an OPS-compliant computer (commercially
available), turn on the cooling fan.

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. [approximately 30.1 kg (with the
optional stands)]
When using screw hooks (commercially available), use ring
hooks, not C-hooks (with opening).

400 mm

Screw holes

Screw hook, etc.
(commercially available)

English

Don’t block these holes.

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.

Rope, etc.
(commercially available)

Clamper

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
suffi 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.
