How to Use
Preparation for useEnglish-13
P-1 Preparation for installation
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 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 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)]
When using screw hooks (commercially available), use ring
hooks, not C-hooks (with opening).
• 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
• 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.
Determine the installation location
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.
MOVING OR INSTALLING THE LCD MONITOR MUST BE DONE BY TWO OR MORE PEOPLE.
Failure to follow this caution may result in injury if the LCD
Proper operation of the monitor is not guaranteed when it is
mounted upside down or face down.

TERMINATION] of the slave monitor at the end to OFF. See page 53.
5. A control application made by the customer reads the value from two brightness sensors of any monitor and distributes it to all
monitors. For the specifi cations of the communication commands, contact your dealer.
When using CAT5 for control only, you can connect up to 26 monitors. When using the video function together, you are
recommended to connect only 4 or less monitors due to the restrictions of the video function. See page 25.English-60
