Rosen A8 Owner’s Manual
INTRODUCTION
To get the most enjoyment from using your system, please read
these instructions.
Your system includes the following components:
· An integrated widescreen flat panel display
· Aninternal DVD/CD/MP3Player
· Wireless Infrared (IR) Headphones (2 pair) (AC 3003)
· A Remote Control (AC3025)
· A Stereo FM Modulator (lets system sound be heard over your
vehicle’s speakers)
· Other parts and cables installed out of sight in your vehicle
In order to operate the system, the
vehicle ignition key switch must be
in the ACC or engine ON position.
WARNING!
Operate the system with the engine
running, if possible. To avoid a dead
battery, do not use the system for long
periods of time without starting the
engine.
Precautions
•Use this system only if properly installed by a qualified installer.
•If the units show signs of overheating or malfunction, power off
the unit and consult your dealer immediately. Do not open the unit -
there are no serviceable parts inside.
•Do not press on the display surface; this can damage it.
•Clean the LCD panel with a slightly damp, soft cloth using
household glass cleaner. Do not use solvents such as benzene,
thinner, or commercially available cleaners.
•If your car was parked in a very cold or very hot place, the
picture may not be clear, or you may see a temperature warning
on the screen instead of a picture. The system is not dam-
aged. The picture will return and become clear after the system
temperature returns to normal.
•When using portable radios and telephones near the system,
picture or sound interference may occur.
Notes:
The system’s operating voltage range is 11-16VDC operat-
ing voltage. The system operating temperature is 0oto 60o
Celsius (32Oto 140OFahrenheit). Use of the system beyond
the safe operating ranges listed can cause temporary or
permanent damage to the unit, and such damage may not
covered by the manufacturer’s warranty.
When using optional wired headphones, use headphones
with a volume control, such as the Rosen AC3004. The
system has no volume adjustment - use the volume control
on the wireless headphones or on the vehicle radio.

DISCSPLAYED
Compatible Discs
DVD, Video CD (VCD), CD/CD-R, and MP3 discs are compatible with
the system. The identifying logo and description of each disc type is
given below.
DVD 12 cm disc/8 cm disc
(single-sided disc only)
Video CD 12 cm disc/8 cm disc
CD/CD-R,MP3 12 cm disc/8 cm disc
DVDRegions
This DVD player is designed and manufactured to respond to the
Region Management Information that is recorded on a DVD disc. If the
Region number described on the DVD disc does not correspond to
the Region number of this player, it will not be able to play the DVD
disc. Some DVD discs are manufactured to operate in “all” zones,
and those discs are compatible with this player.
DVD Region Icons:
These icons on the DVD case indicate the region code.
Incompatible Discs:
The following disc types are incompatible:
· DVD-ROM
· DVD-R/DVD-RW/DVD-RAM
· PhotoCD
· CD-ROM
· CD-Audio manufactured with certain copy protection methods
· Any DVD with a different Region number than the unit.
· Any disc that does not meet DVD Consortium standards.
DVD Operations that differ from disc to disc
When a DVD disc is created, the creator has to define how the disc
will operate when it’s loaded into a DVD player. For instance, some
discs begin playing immediately, while other discs only display a menu
and require a menu selection to be made before playback will start.
The DVD standard also allows the maker of a DVD disc to disable
certain functions at certain times, such as Fast-forward and Stop
(which is why you can’t skip past the copyright warning screen). If
some feature cannot be used, usually the disc is temporarily
preventing the player from executing the operation.
Discs which do not properly load
Some homemade discs which do not have all the data needed to
properly initialize all DVD players may not load properly, and may
create a state where the DVD player will not eject the disc at all. In
these cases, you must have your Rosen authoriozed dealer reset
the system.

Rosen A8 Owner’s Manual
Note: While it is not technically a “monitor” setting, the
internal DVD player can be configured for either a widescreen
16:9 output compatible with the 8” screen, or for a a standard
4:3 output. Using the correct “WIDE” setting will eliminate or
greatly reduce the “black bars” on the top and bottom of the
screen when viewing a widescreen DVD. See page 20 for
more information.
Using the Dome Lights
The system has built-in dome lights for interior illumination. In many
vehicles, this feature replaces an original factory dome light, which is
sometimes displaced by installation of the system. The dome lights
are controlled by both the Dome Light button on the front panel, and
by the matching Dome Light button on the remote control.
When the lights are off, press either button to turn them on.
When the lights are on, press either button to turn them off.
When the lights have been turned on manually using the Dome Light
button, they will automatically turn off after all the doors are closed.
ENTER
OPEN
SOURCE
Note: Some vehicles have a dome light dimming feature that
causes the light to fade out gradually. The system light may
not fade in the exact manner as the factory dome light, but will
still turn on and off normally in conjunction with the use of the
vehicle’s doors. This is proper operation for the system. If you
have any questions, contact your Rosen authorized dealer.
Changing Monitor Settings
Display Adjustments: The A8 monitor has adjustable video settings.
To change these settings, press the ENTER button on the overhead
console and hold it for two seconds. A menu with the following

TINT (32)
To select a setting to be changed: Press the DOWN button to move
the cursor down the menu list (it will cycle back to the the top).
To change the value of a setting: Use the LEFT and RIGHT arrow
buttons to decrease and increase the value of the setting. The range
is zero to 63, with 32 as the default.
To exit the menu: Press the ENTER button to save the settings and
exit the menu.
Selecting among various display modes: The A8 has a
“widescreen” display, with a 16:9 aspect ratio (the same aspect ratio
as high-definition televisions).
•To view widescreen DVD’s, press the DISPLAY MODE button
until “Wide” is displayed on the screen.
•To watch “fullscreen” DVD’s or broadcast television (using an

LISTENINGOVER THE CARSPEAKERS
The A8 uses an FM Modulator to send audio through the vehicle radio
and thus through the speakers. To listen to A8 system audio through
your car speakers:
1 Press SPEAKER. “Speaker Sound Enabled” will appear on the
screen. (If “Headphone Sound Only” appears, press SPEAKER
again.)
2 Turn on the car radio. Make sure MUTE is off. Tune to FM

to store the FM Modulator frequency as a preset on your radio for
ease of use. This will be either 87.9 or 88.3 FM.
Note: When the FM Modulator is on, you may notice some
reduced radio reception. When the system is off, the FM
Modulator also turns off. To listen to the radio when the
system is not in use, close the monitor, and both the system
and the FM Modulator will turn off.
Note: If there seems to be a strong station on the FM
Modulator frequency, your Rosen authorized dealer can
switch the system to the alternate frequency.

ROSENENTERTAINMENT SOUND FEATURES
RES Surround-sound. (DVD audio only). While many of us have
home theatre systems with center-channel speakers and subwoofers,
Rosen knows that most of us don’t have that luxury in our vehicles. So
Rosen’s surround-sound circuitry re-creates surround effects when
watching movies – especially when using headphones!
RES Sound Processing. (DVD audio only). Movie soundtracks were
meant to be heard in a quiet theatre – not in a moving car! The dialogue
can be difficult to hear over road noise, and the most dynamic portions
of the soundtrack can overpower the car’s sound system.
With RES Sound Processing turned on, dialogue is automatically louder
and easier to hear, while loud passages, such as special effects, are
automaticallylowered slightly.TryRES whetheryou arelistening through
the car speakers or wearing headphones, and use it whenever you
find it improves the sound.

Rosen A8 Owner’s Manual
Motion picture film and cameras, and later
television screens, were originally designed
around a screen size that was almost square - it
was one-third wider than it was high (another
way to say this is that it had a width-to-height
ratio, or aspect ratio, of 4:3. This ratio, 4:3, can
also be expressed as 1.66:1.)
When widescreen movies using technologies
like Cinemascope and Panavision became
popular, new aspect ratios were used
for them - 1.78:1, 2.35:1, and even 2.55:1.
When high-definition television was
developed, a screen shape of 16:9, or 1.85:1,
was selected as the best compromise for
viewing widescreen movie images.
When you watch widescreen movies on a
standard 4:3 television, there are “black bars”
on the top and bottom of the screen. This is
often called a “letterbox” image. The alternative
is called “pan-and-scan”, where the edges of
the image are “cropped” off.
This system uses a widescreen 16:9, or 1.85:1
display - the same aspect ratio as high-
definition televisions. This means that when
viewing widescreen DVD’s, these black bars
are either non-existent, or greatly minimized.
WHY ARE THE BLACK BARS STILL THERE SOMETIMES?
There are three possible reasons for black bars to appear on the top
and bottom of the system’s display:
1) You are watching a widescreen movie with an aspect ratio
greater than 1.85:1.
Check the disc jewel box to determine the DVD’s aspect ratio - if
you see “2.3:1”, ” 2.33:1”, or ”2.35:1”, this applies to you.
2) The internal DVD player has been set for a 4:3 display instead of
the built-in 16:9 wide display. See DVD Setup, Page 23, to correct
this.
3) The “widescreen” DVD movie you are viewing is not “anamorphic”
or “enhanced for widescreen televisions”. These films, often older
DVD conversions, are not recommended for viewing on
widescreen displays, since they will not flll a wide screen -
instead, you often end up with a “picture frame’ effect. You can
usually determine if your DVD was produced for optimum
compatibility with widescreen televisions by looking for the word
“anamorphic” or the phrase “enhanced for widescreen
televisions” on the box.
