a Windows or desktop publishing environment, where smaller screen
sizes result in images difficult to see easily. The anti-glare treatment is
easy on the eyes.
The microprocessor-based On Screen Display (OSD) controls allow
you to adjust a

variety of image controls, automatically storing up to

37
different video modes, including 6 pre-set modes.
For greater user health and safety, this monitor complies with the
Swedish Nutek MPR II requirements for low radiation emissions.
For low cost of monitor operation, this monitor is certified as meeting
the EPA Energy Star Requirements, and utilizes the VESA Display

Important Precautions

This unit has been engineered and manufactured to assure your
personal safety, but improper use can result in potential electrical
shock or fire hazard. In order not to defeat the safeguards
incorporated in this monitor, observe the following basic rules for its
installation, use, and servicing. Also follow all warnings and
instructions marked directly on your monitor.

On safety

1. Use only the power cord supplied with the unit. In case you use

another power cord, make sure that it is certified by the applicable
standards (UL/CSA or VDE) if not being provided by the supplier.

2. Operate the monitor only from a power source indicated in the

specifications of this manual or listed on the monitor. If you are not
sure what type of power supply you have in your home, consult
with your dealer.

3. Overloaded AC outlets and extension cords are dangerous. So are

frayed power cords and broken plugs. They may result in a shock
or fire hazard. Call your service technician for replacement.

4. DO NOT OPEN THE MONITOR. There are no user serviceable

components inside. There are Dangerous High Voltages inside,
even when the power is OFF. Contact your dealer if the monitor is

Power Management System

This monitor incorporates new circuitry for lowering energy usage
during idle time, following the Display Power Management Signalling
(DPMS) guide lines of the Video Electronics Standards Association
(VESA), and is certified as exceeding the EPA's Energy Star program
for reduced power usage.
For the power savings feature to operate, the monitor must be used with
either a PC having power saving circuitry. The monitor has three power­saving states, and the power saving operation is indicated by the power
indicator on the front panel.
When the power indicator is green, operation is normal. When the
power indicator is Amber, the monitor is in a power saving mode.
If the power indicator is Amber, press the power button to turn on the
monitor. If the power indicator is Amber and you wish to use the PC
again, move your mouse pointer or touch a keyboard button. When the
monitor is not in use, save energy by turning it off.

Video Memory Modes

This multi-synchronous auto-scanning monitor can automatically
detect and display several video modes falling within the monitor's
scanning range of 30-70kHz Horizontal and 50-120Hz Vertical. In the
PC area, this relates to a maximum flicker free usable resolution of
1280 x 1024 at a non-interlaced refresh rate of 60Hz Vertical.
For convenience, the monitor has a 37 mode memory, of which 6
modes come from the factory preset to popular video modes as
described below.

Modes 13-37 are empty and can accept new video data.

If the monitor detects one of the above signals from your computer's
video card, it will recall that mode and any stored image adjustments
you may have made before. If the monitor detects a new video mode
that had not been present before or is not one of the above listed
factory presets, it will store a new mode automatically in one of the
blank (empty) memory modes (in this example, mode 13). When you
now adjust the OSD controls to your preference, these image settings
will also be stored in mode 13. Whenever your video card or PC
switches

to the mode that the monitor recognizes as mode 13, your

personal image

settings will also be recalled.

A note about the video memory modes:

There is a total of 37 video memory modes, generally more modes than
you will use at any one time. Of these 37 modes, 6 are permanent,
factory fixed modes that cannot be changed, and another 6 are set at the
factory, but may be overwritten to make more room. The remaining 25
modes are left blank (empty). If you use up the 25 blank modes and still
have more new video modes, the monitor will store information in the
other 6 soft preset modes for the new mode storage. If additional new
modes are encountered, the monitor will delete the lowest memory mode
and add the new mode.
If you use a video card that has a number of resolutions and frequencies
that do not correspond to any of the monitor video modes set at the
factory, here's what will happen:

1) As the monitor encounters new video data, if you adjust the image
control icons, the monitor will save the new information in the next
available empty mode (mode 13 if this is the first new data
encountered).

2) If you have used up modes 13-37 with 25 new video modes, and the
monitor encounters another mode (38th mode), it will store the new
data in mode 13 and the old data of mode 13 is deleted.
In addition, If the monitor encounters 39th new video data, the old
data of mode 14 is deleted and 39th data will replace the mode 14,
with above method, when this monitor encounters new mode, it can
update from mode 13 to mode 37 sequentially and continuously.

Because the monitor is designed this way, you will always have the
most recent 31 video modes generated by your graphics card
available with your own image settings recalled automatically.

Microphone Operation

On the left side there is a MIC (Microphone) jack. By plugging a
microphone in here, it may reduce the long length of cable needed to
reach the PC's sound card. In order to use this MIC jack, you need to
use the cable (supplied) to plug into the rear of the monitor (MIC
OUT) and into the MIC input jack of your sound card (if available).
If you lost the supplied cable, consult with your dealer or buy a stereo
cable.

Audio Features

A major feature of this monitor is its built-in audio system. This
conveniently integrates a stereo audio amplifier and speakers without
taking up any more space. Because the monitor is designed like this,
you can easily upgrade to audio capable multimedia applications by
attaching your PC with sound card to the back of this monitor. It will
result in significantly less cabling and space requirements.

Audio Connections

Use the supplied cable to attach to the rear of the monitor (AUDIO IN)
and to the sound card in your PC (line out). The cable will carry both
left and right channel signals in one wire. Make sure when you use
the PC to turn up the volume of the sound card all the way.

A19

Low Radiation Compliance (MPR II)

This monitor meets one of the strictest guidelines available today for
low radiation emissions, offering the user extra shielding and an anti­static screen coating. These guidelines, set forth by a government
agency in Sweden, limit the amount of emission allowed in the
Extremely Low Frequency (ELF) and Very Low Frequency (VLF)
electromagnetic range.

Self Diagnostics

This monitor can sense when there is a possible problem present,
and informs you of this condition by presenting you with a SELF
DIAGNOSTICS OSD. This OSD may pop up when it is On but no
signal is detected. In this case the message NO SIGNAL DETECTED
will be high lighted, alerting you to check the signal cable
connections.

DDC (Display Data Channel)

DDC is a communication channel over which the monitor
automatically informs the host system (PC) about its capabilities.This
monitor has DDC function; DDC2B carry out uni-directional
communication between the PC and the monitor. Under these
situations, the PC sends display data to the monitor but not
commands to control the monitor settings.

NOTE : PC must support DDC functions to do this.

Some older computer systems are not compatible with the
DDC standard. If your monitor is displaying a monochrome
image or the wrong resolution, need to change with a DDC
compatible VGA card.
