FCC INFORMATION
This equipment has been tested and found to comply with the limits of a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are 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 installation. 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.

9. Precautions

Please pay attention to the followings when you use this TFT LCDmodule.

9-1. Mounting Precautions

(1) You must mount a module using holes arranged in four cornersor four

sides.

(2) You should consider the mounting structure so that uneven force (ex.

Twisted stress) is not applied to the module. And the case on which a

module is mounted should have sufficient strength so that external force is

not transmitted directly to the module.

(3) Please attach the surface transparent protective plate to the surface in

order to protect the polarizer. Transparent protective plate should have

sufficient strength in order to the resist external force.

(4) You should adopt radiation structure to satisfy the temperature

specification.

(5) Acetic acid type and chlorine type materials for the cover case are not

desirable because the former generates corrosive gas of attacking the

polarizer at high temperature and the latter causes circuit break by

electro-chemical reaction.

(6) Do not touch, push or rub the exposed polarizers with glass,tweezers or

anything harder than HB pencil lead. And please do not rub with dust

clothes with chemical treatment. Do not touch the surface of polarizer for

bare hand or greasy cloth.(Some cosmetics are detrimental to the

polarizer.)

(7) When the surface becomes dusty, please wipe gently with absorbent cotton

or other soft materials like chamois soaks with petroleum benzine.

Normal-hexane is recommended for cleaning the adhesives used to attach

front / rear polarizers. Do not use acetone, toluene and alcohol because

they cause chemical damage to the polarizer.

(8) Wipe off saliva or water drops as soon as possible. Their long time contact

with polarizer causes deformations and color fading.

(9) Do not open the case because inside circuits do not have sufficient

strength.

9-2. 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.)

(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, smearor 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. Sufficient suppression to the

electromagnetic interference shall be done by system manufacturers.

Grounding and shielding methods may be important to minimized 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.
