Introduction
The Trust Precision Viewer 15" monitor is a microprocessor-based, digital-controlled, multiple
frequency colour monitor. Microprocessor-based intelligence allows precise operation with
graphic adapters between 30kHz and 54kHz horizontal frequency.
Users are able to set display parameters according to their own display adapters and to their own
preference.
Display adjustments, including brightness, contrast, image size and position, geometry distortion
compensation are digitally controlled. While adjustment settings for some standard graphic modes
have been preset during manufacture, additional user settings for both standard and non-standard
signals may be installed in the monitor's memory.
We hope that you will find this manual helpful in making the best use of your monitor, and in
ensuring your personal safety during operation.
Chapter 1 explains how to install the Precision Viewer 15".
Chapter 2 describes how to operate the monitor.
Chapter 3 gives solutions to problems.
Appendix A provides lists of monitor specifications and gives signal connector information.
Appendix B provides information on multi-media speakers.
Safety precautions
Power Input
See paragraph 1.1 "Connecting the power cord". Do not modify the three-pronged grounding type
monitor power plug in any way.
Installation
•Do not place the monitor on an unstable cart, stand, or shelf where it may fall and injure
personnel or damage equipment.
•Route power cords so that they cannot be walked upon or tripped over. Do not allow anything
to be placed on the power cord.
•Do not install the monitor in a damp place, or where it may be exposed to rain or water. Avoid
spilling liquid of any kind on the unit.
Ventilation
•Do not block or cover ventilation openings on the back or bottom of the monitor cabinet.
•Do not place the monitor near a radiator or heating vent.
•Do not push objects of any kind through cabinet openings. This may result in fire or electric
shock.
•When replacement parts are required, make sure that the service technician uses components
specified by the manufacturer and having the same characteristics as the original components.
Unauthorised substitutions may result in fire, electric shock, or other hazards.
•Upon completion of any service or repairs, ask the service technician to perform safety checks
to ensure that the equipment is in safe operating condition.
Attachments
Signal sources should be of approved types and properly grounded. Ask a service technician to
perform routine safety tests to determine whether equipment is in safe operating condition.
Differences in ground potentials between the monitor and AC power systems may cause signal
instabilityand present a shock hazard. Ground potential tests should be part of the routine safety
check made by the service technician.

6-EN EN-7
Cleaning
Unplug the power cord from the unit before cleaning the display. Use only a damp cloth. Do not
use alcohol, spirits, or ammonia to clean the display.
Note
Do not attempt to clean the interior of this unit - this will be done by the service technician as part of normal
maintenance procedures.
Servicing
Refer all servicing to qualified service personnel.
Note
Serious shock hazards exist within the covers of this monitor. Do not open the covers under any circumstances.
There are no serviceable parts inside.
Unplug the unit immediately and notify the service technician if:
•Liquid has been spilled into the unit, or the unit has been exposed to rain or water.
•The unit has been dropped or the cabinet damaged.
•Fuses continue to blow.
•The power cord is damaged.
•A distinct change from normal operation is apparent.
Chapter 1 - Installation of the Precision Viewer 15"
1.1 Connecting the power cord
Check first to make sure that the power cord you use is a correct type required in your area. This
monitor has an auto-ranged power supply that allows operation in either a 100/120V AC or a
220/240V AC voltage area. (No user adjustment required.)
First connect the power cord first with your monitor's power input socket, then plug the other end
into a 3-pin AC outlet. The power cord may be connected to either a wall socket or the power
output socket on your PC, depending on the type of power cord supplied with your monitor.
1.2 The tilt/swivel base
•To connect the tilt/swivel base to the monitor, align hooks with the sockets on the bottom side
of the monitor, and gentlypush the base towards the front of the monitor, as indicated in the
diagrams below.
•Before operating the monitor, adjust the unit on the tilt/swivel base to the most comfortable
operating position.
•To release and disconnect the tilt/swivel base, lift the catch on the rear of the base, and gently
pull the base towards the rear of the monitor.

1.3 Positioning the monitor
Place the monitor in a convenient location close to your personal computer. We suggest that the
unit be positioned so that the top of the screen is just above eye level.
1.4 Connecting the signal cable
The 15-pin D-shell signal connector on the signal cable will connect easily to the video adapter
output on your personal computer. Lock both screws on the connector to ensure a firm connection.

Chapter 2 - Using the monitor
2.1 Turning the monitor on
1. Turn the PC power switch ON. Then turn the monitor power switch ON, bypressing the
switch inward. The green power indicator will light up.
2. Allow about 30 seconds for the CRT tube to warm up. Data will be displayed on the screen.
3. To turn the monitor OFF, press the switch again.
4. If your display fails to function properly, try to solve the problem with the information in
Chapter 3 "Troubleshooting".

The user control parameters are selected in sequence by pressing the SELECT button in the front
panel, the selected parameter is indicated by the illuminated LED(s), the function is described
below:
1Contrast
2Brightness
3 Horizontal Size
4 Horizontal Phase
5 Vertical Size
6 Vertical Centring

8 Trapezoid; then repeat from sequence 1.
Each parameter can be adjusted with the "+" and "-" buttons.
When the control value reaches the maximum value (either positive or negative end), the LED
will flash, indicating that no more adjustment value increase/decrease is possible.
The manual "Degaussing" function enables the user to clear the picture impurity caused by
monitor position/orientation change.
The "Recall" function is activated by pressing the "+" and "-" buttons simultaneously.
There are a total of 16 factory preset modes and 14 user modes allowed. For the factory preset
modes, all parameters have been set and stored permanentlyin the memory, according to the
standard VESA timing. The factory preset data can be "recalled" to initial values any time during
operation even if they have been modified by the user through external user controls.
User modes are left to users for the special timings they may want. All the user adjustments are
stored in the memory automatically after the adjustment is finished, these values remain stored
after the power is turned off.

12-EN EN-13
2.3 Power saving
The monitor will go into different power saving states upon receiving control signals from the
displaycontroller, this meets the EPA (Environment Protection Agency) Energy Star requirements
and reduces power consumption.
The monitor will work in the following 4 states according to the VESA standard Display Power
Management Signal:
STATE POWER CONSUMPTION LED LIGHT
ON Normal Green
STANDBY <15W Yellow
SUSPEND <15W Yellow
OFF <5W Amber
The power saving states will be maintained until a control signal has been detected or the
keyboard or mouse is activated. The recovery time from STANDBY/SUSPEND modes to ON
state shall be within 3 seconds. It will take about 15 seconds from OFF state back to ON state.
Chapter 3 - Troubleshooting
If your monitor fails to operate satisfactorily, it maybe possible to correct the problem by making
simple checks as follows:
Problem Check and adjust
Blank screen •Monitor power switch, power cord, signal cable, or
connector.
•PC power switch.
•Brightness & Contrast controls.
Display position off-centre Horizontal phase & vertical centre controls
Display size too small or too large Vertical size control & horizontal size controls
Display too bright or too dim Brightness & contrast controls
Refer to the operation instructions for your computer/video adapter to ensure that you have the
correct signal output source for the monitor. Ensure that the switches on the video adapter are set
correctly for operation with this monitor.
If the above steps fail to correct the problem, contact your dealer for servicing by qualified service
personnel.
Please remember that the monitor should be returned for servicing together with the power cord.
