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.

Please pay attention to the followings when you use this PDP module.
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) You should adopt radiation structure to satisfy the temperature
specification.
(4) Acetic acid type and chlorine type materials for the cover case are not
desirable because the former generates corrosive gas of attacking the
latter causes circuit break by electro-chemical reaction.
(5) 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
surface. Do not use acetone, toluene and alcohol because they cause
chemical damage to the glass filter.
(8) Wipe off saliva or water drops as soon as possible. Their long time contact
with glass filter causes deformations.
(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) Brightness depends on the PATTERN.
(3) Be careful for condensation at sudden temperature change. Condensation
makes damage to electrical contacted parts. And after fading condensation,
smear or spot will occur.
(4) When fixed patterns are displayed for a long time, remnant image is likely
to occur.
(5) 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.
9-3. HANDLING PRECAUTIONS 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.
(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.
