Safety Approvals

 CE Marking

 FCC Class A

 FCC Compliance

This equipment has been tested in compliance with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These
limits are meant to provide reasonable protection against harmful
interference in a residential installation. If not installed and used in
accordance with proper instructions, this equipment might generate or
radiate radio frequency energy and cause harmful interference to
radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following methods:

1. Increase the separation between the equipment and receiver.

2. Connect the equipment to another outlet of a circuit that
doesn’t connect with the receiver.

3. Consult the dealer or an experienced radio/TV technician for
help.

Shielded interface cables must be used in order to comply with the
emission limits.

iv

Safety Precautions

Before getting started, please read the following important safety
precautions.

1. The DSH-146 series does not come equipped with an

operating system. An operating system must be loaded first
before installing any software into the computer.

2. Be sure to ground yourself to prevent static charge when

installing the internal components. Use a grounding wrist
strap and place all electronic components in any static­shielded devices. Most electronic components are sensitive
to static electrical charge.

3. Disconnect the power cord from the DSH-146 series before

any installation. Be sure both the system and external
devices are turned OFF. A sudden surge of power could ruin
sensitive components that the DSH-146 series must be
properly grounded.

4. Make sure it is the correct voltage of the power source

before connecting the equipment to the power outlet.

5. The brightness of the flat panel display will be getting weaker

as a result of frequent usage. However, the operating period
varies depending on the application environment.

6. The flat panel display is not susceptible to shock or vibration.

When assembling the DSH-146 series, make sure it is
securely installed.

7. Do not leave this equipment in an uncontrolled environment

where the storage temperature is below 0℃ or above 40℃.
It may damage the equipment.

8. External equipment intended for connection to signal

input/out or other connectors shall comply with relevant
UL/IEC standard.

9. Do not open the back cover of the system. If opening the

cover for maintenance is a must, only a trained technician is
allowed to do so. Integrated circuits on computer boards are
sensitive to static electricity. To avoid damaging chips from
electrostatic discharge, observe the following precautions:

z Before handling a board or integrated circuit, touch an

unpainted portion of the system unit chassis for a few
seconds. This will help to discharge any static
electricity on your body.

z When handling boards and components, wear a wrist-

grounding strap, available from most electronic
component stores.

2. Environmental Requirements

 Operating temperature: -5°C to 45°C
 Storage temperature: -40°C to +85°C
 Humidity, non-condensing: 20% ~ 90%RH, Non-

Condensing

NOTE DSH-146 Power supply should be protected the system

when it is superheat. If the system inside temperature is
over 70 degree, it will enable overheating solution to turn
off system power.

NOTE it is regular phenomenon that seeing the mist under glass ,

because you boot up the system when it is leaved unused
for a long term and it is difficult for humidity between
environment and system.
The system should keep standing perpendicularly to avoid
the mist phenomenon.
