3.0 Installation
3.1 Prior to installation, the following items should be considered:
3.1.1 During the design and layout of the aircraft cabin, careful
consideration of the location of this module is necessary. Some of
the items to be considered include:
•Space
•Available power supply
•Environmental conditions (temperature, humidity, etc.)
•Length of cable runs
3.1.2 The LCDHW-420-BN1-x shall be installed to conform to the
standards designated by the customer, installing agency, and
existing conditions as to the unit location and type of installation.
3.1.3 An internal cooling fan ventilates internal components and prevents
undesirable heat buildup. Proper ventilation must be allowed for
when specifying the installation location. The closeout area of the
monitor shall have a clearance of 2 inches (5.08 cm) minimum for
the air inlet and exit areas. The closeout area of the monitor case
shall not block the air inlet or exhaust openings of the monitor case.
This fan is thermostatically controlled, it only runs when the unit is
turned on and heat build-up requires it, providing a much quieter
viewing experience than many monitors.
3.1.4 The monitor casing is specially designed for EMI and noise filtering,
guaranteeing a reduction in interference to ensure a high-quality
display.
3.1.5 A shallow mounting depth makes this monitor ideal for bulkhead
use. Convenient mounting holes are strategically located on the left
and right sides, as well as the back of the unit. The unit has eight
(8) 8-32 UNF-2B on the left and right sides, four (4) on each side.
The maximum depth should be no more than 0.50 inches. In
addition, the unit has eight (8) 8-32 UNF-2B on the back. The
maximum depth should be no more than 1 inch. Refer to Section
7.0, Reference Drawings, for mounting hole diameters and
configuration.
3.1.6 The monitor should be located as close to the source equipment as
possible in order to reduce the possibility of noise introduced into
the video. Refer to Section 6.0 for unit dimensions.
3.1.7 A grounding lug is included as part of the housing. See Section 7.0
for details.

3.1.8 The maximum length of the connection to PC Graphic (VGA) input
is 15 feet.
3.2 Unpacking and Inspection
3.2.1 Carefully open the packaging and remove the LCDHW-420-BN1-x.
Verify that all components have been included in the package per
the packing list. Inspect the unit for damage. Retain the packing
materials and packing list.
3.2.2 If damage has occurred during shipping, a claim should be filed
with DeCrane Aerospace Audio International WITHIN 24 hours and
a Return Request Authorization Number shall be obtained from
DeCrane Aerospace Audio International by contacting the Repair
Department at 501.801.8101. Repackage the unit in its original
packaging materials and return it to DeCrane Aerospace Audio
International following instructions given by the DeCrane
Aerospace Audio International representative. Refer to the front
cover of this manual for address. If no return is necessary, retain
the packing list and the packing materials for storage.
3.3 Cautions and Warnings
3.3.1 It is important to do a pin-to-pin power and ground check on all
connectors. Ensure that power and ground are applied only where
specified. Damage to the unit may result if power or ground is
applied to the wrong points.
3.3.2 DO NOT connect or disconnect the monitor while power is applied.
3.3.3 DO NOT remove any factory-installed screws. Damage to the unit
may result and void any warranties.
3.3.4 DO NOT expose to moisture.
3.3.5 ESD (Electro Static Discharge) guidelines shall be followed.

4.0 Instructions for Continued Airworthiness
No periodic scheduled maintenance or calibration is required for continued
airworthiness of the LCDHW-420-BN1-x. If the unit fails to perform to
specifications, it must be removed and serviced by a qualified service facility.
5.0 Troubleshooting
5.1 Cleaning Method
The LCDHW-420-BN1-x should be cleaned when excessive dust or dirt
becomes apparent.
Use a twin pack cleaning system that employs a wet pad pre-moistened
with an Isopropyl Alcohol based cleaner/anti-static solution and a lint-free
drying cloth. DeCrane Aerospace Audio International recommends using
“Kleen & Dry” RR1205 manufactured by READ RIGHT, Nanuet, NY
10954.
Do not use benzene, ammonia, thinner, or any other volatile
substance to clean the monitor or screen. These chemicals may
damage the screen or internal circuitry.
Do not allow cleaner to puddle or pool around edges. Seepage
may damage internal circuitry.

DeCrane Aerospace Audio International LCDHW-420-BN1-x Installation Manual
Document # 540390, Rev IR, 08/2010 Page 12 of 16
DeCrane Aerospace Audio International’s recommended cleaning method
follows:
A. Turn off monitor.
B. Open pre-moistened pad and gently wipe evenly across
display glass. Do not allow solution to “pool” or puddle
around display edges.
C. Immediately dry display using the absorbent, lint-free cloth.
Gently wipe display to a dry, clear finish.
5.2 General Troubleshooting Procedures
•Verify power to the unit by rechecking +28 VDC power is applied to the
proper pins on the unit. Use a voltmeter to verify correct level.
•Remove power from the unit for at least one (1) minute and reapply
power.
•Recheck all connections to the unit for security. Check all harness runs
for possible pinching. Recheck all pinouts for application accuracy.
•Check data bus integrity by utilizing a voltmeter, oscilloscope, or other
voltage instrument to verify proper input voltage on the data bus pins.
Typical measurements are as follows:
A to Ground: 4.0 to 4.5 VDC
B to Ground: 0.1 to 1.0 VDC
If any device is transmitting (i.e., holding bus active), then these typical
measurements would be reversed for the A-to-Ground and
B-to-Ground. This troubleshooting tool can help indicate a data bus
lockup. If this occurs, remove the data bus from all other equipment
one piece at a time. As each is removed, check the bus status to see if
it is now functioning properly. Once you have removed the piece or
pieces of offending equipment, disconnect power and then reconnect
everything but the suspect component. Reapply power and then test
the functionality of the unit(s).
