Section 1 - General Information  
Congratulations on purchasing a MaxTech 14-inch Color Monitor. The  
monitor has one of the finest CRTs available in the industry, providing a  
full range of video display resolutions and complies with the MPR-I  
standard to reduce electromagnetic emissions.  
The monitor has a 0.28 mm dot pitch display with a 65 MHz video  
bandwidth. It supports video resolutions ranging from 640 x 350 to 1024  
x 768 (non-interlaced).  
The monitor can be used with video cards supporting VGA, SVGA, IBM  
8514/A or XGA modes and provides an unlimited palette of colors.  
1.1  
Precautions When Using the Monitor  
When setting up and using your monitor, pay special attention to the  
following:  
• To eliminate eye fatigue, do not use your monitor against a bright  
background or where sunlight or other light sources will shine directly  
on the monitor.  
• Your monitor should be placed just below eye level for optimum  
viewing.  
• Allow adequate ventilation around the monitor so that heat from the  
monitor can properly dissipate.  
• Neither the monitor itself nor any other heavy object should rest on the  
power cord. Damage to a power cord can cause fire or electrical  
shock.  
• Keep the monitor away from high capacity transformers, electric  
motors and other strong magnetic fields.  
• Do not use your monitor in a damp, dusty or dirty area.  
• Handle the monitor with care when transporting.  
• Unplug the monitor during electrical storms.  
1.2  
Power Saving Modes  
The MaxTech monitor supports VESA Display Power Management Sig-  
naling (DPMS) SUSPEND and OFF modes. DPMS defines a method for  
a computer to signal the monitor to reduce its power consumption when  
idle. DPMS features must be supported by both the computer and the  
monitor for them to be available. Computer support of DPMS requires the  
use of a DPMS compliant video card.  
The monitor enters DPMS SUSPEND mode when the computer turns off  
the Vertical Synchronization signal. This power-saving mode reduces the  
monitor’s power consumption to 25W. When the synchronization signal  
is re-enabled the monitor returns to normal operation.  
The monitor enters DPMS OFF mode when the computer turns off both the  
Horizontal and Vertical Synchronization signals. This mode reduces the  
monitor’s power consumption to 5W. When the synchronization signals  
2
are re-enabled the monitor returns to normal operation.

1.Power Indicator: LEDs A, B, and C indicate the state of the Monitor.  
• LEDs A, B and C On – Normal operations.  
• LEDs B and C On – DPMS (Display Power Management Signaling)  
“SUSPEND” mode. The monitor enters SUSPEND mode when the  
computer turns off the Vertical Sync. signal. The monitor is in power-  
saving mode and uses only 25 W.  
• LED C On – DPMS “OFF” mode. The monitor enters OFF mode when  
the computer turns off both the Horizontal and Vertical Sync. signals.  
The monitor is in minimum power mode and uses only 5 W.  
2.Power Switch: Turns monitor on ( | ) or off ( O )  
3.Pincushion: Adjusts the pincushion (shape) of the display  
4.Vertical-Position: Adjusts the vertical position  
5.Vertical-Size: Adjusts the display height
