Installation
Mount the video amplifier in a suitable
location.
Connect the RCA video input and
output cables to the amplifier as
shown in the wiring diagram.
Installation precautions
Choose a mounting location in your
vehicle which is protected from foot
traffic and passengers who might
accidentally disconnect the cables. Be
sure you can see each of the monitors
from the mounting location if you
intend to make the level adjustments
without and assistant.
Do not install the video signal amplifier
in areas which are susceptible to rain,
moisture, direct sunlight, extreme heat
or cold, excessive dust, dirt or humidity.
If installation requires drilling holes or
other modifications to the vehicle,
consult with your nearest dealer or
professional car audio installer.
Use only the installation parts and
hardware provided with the unit to
ensure proper installation. Using other
parts can cause malfunction and
possible damage to your video monitor
or other components in your mobile
video system.
Use only a power source with 12 Volts
DC (negative ground).
Before final installation, temporarily
connect the wiring according to the
diagram near the end of this manual,
check it to ensure that it has been
connected properly, and test the unit
to make sure it is working correctly.
Adjusting the video
signal level
Before starting, rotate the output level
controls on your new video signal
amplifier to MINIMUM.
Turn on the video monitor whose video
input signal you wish to amplify.
Turn on your DVD player (or other
video source), and play a familiar video
program.
At the MINIMUM setting, your monitor
image is probably dark and
unsatisfactory to view. Now slowly
increase the output gain level for that
monitor, until the picture is clear and
bright. Continue to increase the gain
level until you begin to see lines or
other undesirable characteristics in
the picture.
Finally, reduce the gain level back to
the point where you feel the picture
is best from the standpoint of color,
brightness, and freedom from defects.
Leave the control set at this level.
Repeat this process with the other
monitors in your mobile video system.
