including but not limited to: Camcorder, Live-Feed Camera, DVD, VCP
and VCR players as well as Moving Map Systems utilizing NTSC, and
Personal Game Systems.
3.0 Installation
3.1 Prior to Installation
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:
3.1.1 The AI-LCD68-01-xx 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.
3.1.2 Locate the monitor as close as possible to source equipment to
reduce the possibility of noise introduced into the video.
3.1.3 The –02 version's base unit is furnished with MS connector and
hardware to mount connector to base while the –13 version is
furnished with a D-Sub connector. Install mating connector keyway
facing the same direction as the swivel arm keyway to insure
proper alignment.
3.2 Unpacking and Inspection
3.2.1 Carefully open the packaging and remove the AI-LCD68-01-xx.
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 Audio International WITHIN 24 hours and a Return Request
Authorization Number shall be obtained from AI by contacting the
Repair Department at 501.801.0640. Repackage the unit in its
original packaging materials and return it to AI following instructions
given by the AI 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. Audio International recommends using an Electrical
Meter set to read Ohms or an Audible Continuity Tester to confirm
that the pins are connected via wiring. 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 units
may result and void any warranties.
3.3.4 DO NOT expose to moisture.
3.3.5 Maintain an operating temperature of -15°to +55°C (+5°to +131°
F). Storage temperature must remain between -20°to 70°C (-4°to
158°F)
3.3.6 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 in order to help avoid potential noise
sources and ground loops. Length and routing of external cables
should be considered to avoid possible noise sources and ground
loops. 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.

Audio International, Inc. AI-LCD68-01-xx Installation and Operation Manual
Document # 540260, Rev IR, 11/2004 Page 7 of 15
3.4.2 Power Wires
Audio International recommends that power and ground wires be
20 AWG minimum. The chassis shall be electrically bonded to the
airframe structure by a conductive mounting point with <0.1 Ω
resistance using <50 Ωimpedance cable. Aluminum wool, nylon
webbing impregnated with aluminum oxide abrasive or fiber bristle
brushes are the approved tools for removing anodized surfaces at
mounting point where the bonding wire is attached. Power and
Ground wires shall be in accordance with NEMA WC 27500 or
equivalent. Protect power wires with circuit breakers or fuses
located close to the electrical power source bus.
3.4.3 Video Lines
Composite video connections shall be shielded coaxial cable in
accordance with M17/94-RG179 or equivalent. Cable shields shall
be grounded at the source. Use of individual wires rather than
proper coaxial cable connections through production breaks is
unacceptable, and will cause significant and detrimental noise
introduction to the video signal supplied to the AI-LCD68-01-xx.

5.0 Troubleshooting Guide
5.1 Post-Installation Test
5.1.1 Verify +28 VDC power has been connected to the unit.
5.1.2 Ensure that AI-LCD68-01-xx retains full range of motion (see
Section 6.0, Reference Drawings, for motion limits).
5.1.3 Ensure video can be seen on monitor.
5.2 Cleaning Method
AI-LCD68-01-xx should be cleaned at least once every three (3) months
or 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. Audio International, Inc. recommends using “Kleen & Dry”
RR1205 manufactured by READ RIGHT, Nanuet, NY 10954.
 Do not use benzene, ammonia, thinner, or any other volatile
substances 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.
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.
