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.

9-1. MOUNTING PRECAUTIONS

(1) You must mount a module using holes arranged in four corners or 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 polarizes 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 benzene. 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, 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.
