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.

3.4 Wiring Requirements
3.4.1 Introduction
The installing agency shall supply and fabricate all external cables and mating connectors. The length and routing of external cables should be carefully studied and planned before attempting installation of the equipment. Allow adequate space for installation of cable and connectors. Avoid sharp bends and placing cables near aircraft control cables. Maintain a minimum clearance of three (3) inches from any control cable. If wiring is run parallel to combustible fluid or oxygen lines, maintain a separation of six (6) inches between the lines.

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.
Document # 540390, Rev IR, 08/2010 Page 11 of 16
DeCrane Aerospace Audio International LCDHW-420-BN1-x Installation Manual
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).
