Section 1 - General Information
Congratulations on purchasing a MaxTech 15-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 75 MHz video
bandwidth. It supports video resolutions ranging from 640 x 350 to 1280
x 1024 (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.
• Neitherthemonitoritselfnoranyotherheavyobjectshouldrestonthe
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. While in this mode the first LED in
the Power Indicator (LED A in Figure 3-1) is off. When the synchronization
signal is re-enabled the monitor returns to normal operation.
ThemonitorentersDPMSOFFmodewhenthecomputerturnsoffboththe

3
Horizontal and Vertical Synchronization signals. This mode reduces the
monitor’s power consumption to 5W. While in this mode the first and
second LEDs in the Power Indicator (LEDs A and B in Figure 3-1) are off.
When the synchronization signals are re-enabled the monitor returns to
normal operation.
Section 2 - Installation

Push to reset the display to the default parameters.
7. Dual-Function Toggle
Pressing this switch cycles between the two sets of functions
controlledby the fourpairsof buttons (9-12).WhentheFunction
Indicator (8) is off these buttons control Function Group A:
Vertical Position, Vertical Size, Horizontal Position and Horizon-
tal Size. When the Function Indicator (8) is on, these buttons
control Function Group B: Pincushion and RGB Color Adjust-
ments.
8. Function Indicator
Indicates whether Function Group A (LED off) or Function
Group B (LED on) is in effect for controls 9 through 12.
9-12 Dual Function Controls
Controls 9-12 are digital controls. Each control has two buttons, (+) and
(-). The (+) and (-) buttons increase or decrease the value being adjusted,
respectively. Each control is assigned a normal and an alternate function
group which is selected using the Dual-Function Toggle (7). Function
GroupA isselected for adjustment whenthe Function Indicator (8)is off.
FunctionGroupB isselectedforadjustment whenthe Function Indicator
(8) is on.
9.* A. Vertical-Position
