FCC INFORMATION
This equipment has been tested and found to comply with the limit s of a Class B digit al device,
pursuant to part 15 of the FCC Rules. These limits ar e designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy, and if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that the interference will not occur in a particular in stallation. If this equipment
does cause unacceptable 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 measures -- reorient or relocate the receiving
antenna; increase the separation between equipment and receiver; or connect the into an
outlet on a circuit different from that to which the receiver is connected.
FCC WARNING
To assure continued FCC compliance, the user must use a grounded power supply cord and
the provided shielded video interface cable with bonded ferrite cores. Also, any unauthorized
changes or modifications to Amtrak products will void the user’s authority to operate this
device. Thus VINC Will not be held responsible for the product and its safety.
CE CERTIFICATION
This device complies with the requirements of the EEC directive 89/336/EEC with regard to
“Electromagnetic compatibility.”
SAFETY CAUTION
Use a power cable that is properly grounded. Always use the AC cords as follows – USA (UL);
Canada (CSA); Germany (VDE); Switzerland (SEV); Britain (BASEC/BS); Japan (Electric
Appliance Control Act); or an AC cord that meets the local safety standards.

Precaution
Please pay attention to the followings when you use this TFT LCD module
1. OPERATING PRECAUTIONS
(1) The spike noise causes the mis-operation of circuits. It should be lower
than following voltage :
V=±200mV (Over and under shoot voltage)
(2) Response time depends on the temperature.
(In lower temperature, it becomes longer)
CONFIDENTIAL – DO NOT COPY
Page 2-2
File No. SG-0325
Page 7
(3) Brightness depends on the temperature.
(In lower temperature, it becomes lower)
And in lower temperature, response time
(Required time that brightness is stable after turned on becomes longer)
(4) Be careful for condensation at sudden temperature change.
Condensation makes damage to polarizer or electrical contacted parts.
And after fading condensation, smear or spot will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely
to occur.
(6) Module has high frequency circuits. System manufacturers shall do
sufficient suppression to the electromagnetic interference. Grounding and
shielding methods may be important to minimize the interference.
(7) Please do not give any mechanical and/or acoustical impact to LCM.
Otherwise, LCM can’t be operated its full characteristics perfectly.
(8) A screw which is fastened up the steels should be a machine screw.
(9) Please do not set LCD on its edge
(10) Partial darkness may happen during 3~5minutes when LCM is operated
initially in condition that luminance is under 40% at low temperature
(under 5℃).This phenomenon which disappears naturally after 3~5
minutes is not a problem about reliability but LCD characteristic.
2. Handing Precaution For Protection
(1) The protection film is attached to the bezel with a small masking tape.
When the protection film is peeled off, static electricity is generated
between the film and polarizer. This should be peeled off slowly and
carefully by people who are electrically grounded and with well ion-blown
equipment or in such a condition, etc.
(2) When the module with protection film attached is stored for a long time,
sometimes there remains a very small amount of glue still on the bezel after
the protection film is peeled off.

File No. SG-0325
Page 2-3
Page 8
(3) You can remove the glue easily. When the glue remains on the bezel
surface or its vestige is recognized, please wipe them off with absorbent
cotton waste or other soft material like chamois soaked with
normal-hexane.
