1.3 Power Management Function
The monitor has a power management function which
reduces the power consumption of the monitor when not
in use.
The power saving mode is invoked by a VESA DPMS-
compliant computer.  Check your computer's manual for
setting this function.
1.4 DDC
The monitor includes the VESA DDC™ 1 and DDC™ 2B
feature.  DDC (Display Data Channel) is a communication
channel over which the monitor automatically informs the
computer  system  about  its  capabilities  (e.g.  each  sup-
ported resolution with its corresponding timing).
DDC is routed through previously unused pins of the 15-pin
VGA connector.
The system will “Plug and Play” if both monitor and com-
puter implement the DDC protocol.
CAUTION
1.5 Location Considerations
When setting up and using the monitor, keep the following
in mind:
•For  optimum  viewing,  avoid  placing  the  monitor
against  a  bright  background  or  where  sunlight  or
other light sources may reflect on the display area of
the monitor.  Place the monitor just below eye level.
•Place  the  monitor  away  from  strong  magnetic  or
electromagnetic fields, such as high capacity trans-
formers, electric motors, large current  power lines,
steel pillars, etc....
 Magnetism can cause distortion in the picture and/or
color purity.
•Avoid covering the slots or openings of the monitor.
Allow adequate ventilation around the monitor so the
heat from the monitor can properly dissipate.  Avoid
putting the monitor into any enclosure that does not
have adequate ventilation.
•Avoid exposing the monitor to rain, excessive mois-
ture, or dust, as this can cause a fire or shock hazard.
•Avoid placing the monitor, or any other heavy object,
on the power cord.  Damage to the power cord can
cause a fire or electrical shock.
•When transporting the monitor, handle it with care.
1.6 Cleaning Your Monitor
When cleaning the monitor, please follow these guidelines:
•Always unplug the monitor before cleaning.
•Wipe the screen and cabinet front and sides with a
soft cloth.
•If the screen requires more than dusting, apply a
household window cleaner to a soft cloth to clean
the monitor screen.
•Do not use benzene, thinner or any volatile sub-
stances  to  clean  the  unit  as  the  finish  may  be
permanently marked.
•Never leave the monitor in contact with rubber or
vinyl for an extended time period.
•Do not spray directly on the screen as cleaner may
drip into the monitor and damage the circuitry.
•Never use an abrasive cleaner on the screen sur-
face as this will damage the anti-reflection coating.

The Macintosh Adapter is available that converts the 2 row
D-sub video connector on legacy Macintosh computers to
a 3 row D-sub(VGA) connector compatible with your
Mitsubishi monitor.  The Macintosh Adapter is not needed
on G3 (ice and blue) and later version of the Macintosh.  If
the Macintosh Adapter is required for your system, please
contact our Information Support.

2. Set the DIP switches of Macintosh Adapter according
to the setting chart.
(See Section 7.3  Optional Macintosh Adapter AD-
A205 settings.)
3. Connect the 15-pin (DB-15P) end of the AD-A205
Adapter to the straight 15-pin connector on the
Macintosh video port on the computer or on the video
board.
4. Connect the sub-miniature 15-pin (DB9-15P) end of
the AD-A205 Adapter to the signal cable.

tem
Figure 5 shows the signal cable connection to the Video
Graphics Array (VGA) port in an IBM Personal System/2
®series, or any VGA compatible system.
