Mitsubishi Electronics 73 manual Internal Preset Memory Capability, Power Management Function, Ddc

1.2Internal Preset Memory Capability

To minimize adjustment needs, the factory has preset popular display standards into the monitor, as shown in Table 1. If any of these display standards are detected, the picture size and position are automatically adjusted. All of the factory presets may be overwritten by adjusting the user controls. This monitor is capable of automatically storing up to 24 additional display standards. The new display infor- mation must differ from any of the existing display stan- dards by at least 1kHz for the horizontal scan frequency or 4Hz for the vertical scan frequency or the sync signal polarities must be different.

1.3Power 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.

Mode	Power	Power-On Indicator
Normal	73 W	Green
Power Saving Mode	=< 5 W	Orange

1.4DDC

The monitor includes the VESA DDC1 and DDC2B feature. DDC (Display Data Channel) is a communication channel over which the monitor automatically informs the computer system about its capabilities (e.g. each supported resolu- tion 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.

1.5Location 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 colour 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.

1.6Cleaning Your Monitor

When cleaning the monitor, please follow these guidelines:

•Always unplug the monitor before cleaning.

•Wipe the screen and the front and sides of the cabinet with a soft, dry cloth.

•If the screen requires more than dusting, apply a household window cleaner to a soft cloth to clean the monitor screen.

CAUTION

•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.
