INTRODUCTION
Welcome to the Rosen A7 Vehicle Entertainment System Owner’s
Manual. To get the most enjoyment from using your A7 system,
please make sure that you and your passengers take time to read
these instructions.
Your system includes the following components:
· An 7.0” widescreen flat panel display
· An internal DVD/CD/MP3 Player
· Wireless Infrared (IR) Headphones (2 pair)
· A Remote Control
· A Stereo FM Modulator (lets A7 sound be heard over your
vehicle’s speakers)
· Other parts and cables installed out of sight in your vehicle
Precautions
In order to operate the player,
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.
•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. The A7 system is not damaged. The
picture will become clear after the 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 50o
Celsius. Use of the A7 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.
Adjust volume using the volume control on the headphones
or the vehicle radio. There is no volume control on the A7
remote or on the overhead console.

Changing Monitor Settings
Display Adjustments: The A7 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
options appears:
COLOR (32)
CONTRAST (32)
BRIGHT (32)
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 A7 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
optional TV tuner), press until “Standard” is displayed.
•To stretch the picture to take up more of the screen, select the
“Stretch” mode.
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 7” 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 18 more
more information.
Using the Dome Lights
The A7 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 A7 system.
The dome lights are controlled by the Dome Light button on the front
panel of the A7.
ENTER
OPEN
SOURCE
Dome Light
Note: Some vehicles have a dome light dimming feature that
causes the dome light to fade out gradually. The system dome
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.

ROSENENTERTAINMENTSOUND
What makes the Rosen A7 DVD sound better than any other “in-car
entertainment” system? A collection of unique audio features that we
call Rosen Entertainment Sound. Rosen engineers know that true
entertainment isn’t just visual – you’ve got to have great sound! You
won’t find this collection of sonic improvements anywhere but Rosen.
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 – even when using headphones!
RES Sound Processing. (DVD audio only). Movie soundtracks were
meant to be heard in a quiet theatre using a powerful, multi-channel
sound system – not in a moving car with a four-speaker stereo! The
dialogue can be difficult to hear over road noise, and the most dynamic
portions of the soundtrack often 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
automatically lowered slightly. RES provides the best listening experi-
ence inside a car, whether you are listening through the car speakers
or wearing headphones. RES Sound Processing retains the original
fidelity of the soundtrack, acoustically compensated for your vehicle. It
also makes headphone listening even more enjoyable and comfortable.
RES True Two-Channel Stereo. RES uses stereo audio all the way
through the signal chain – even in the FM modulator, a place where
many manufacturers save money and use only mono components.
Rosen believes that in the age of digital multi-channel cinema sound,
two-channel stereo is the minimum acceptable audio solution for DVD
enjoyment.
RES Audio Overdrive. Most “automotive” DVD players operate on 12
volts, and that’s about all that makes them “automotive”. Their DVD chips
put out very low audio output voltages – maybe enough in a home
system, but not enough for use in the challenging electrical environment
of the automobile. RES A7 systems have what we call Audio Overdrive
– we almost double the audio voltage level from the DVD drive on the
way to the rest of the system. Not only is sound quality improved, but
the chances of picking up electrical noise are greatly reduced.

15
Rosen Entertainment Systems
USINGTHEHEADPHONES
Using the headphones allows rear-seat passengers to listen to their
DVD, CD, video cassette, or video game without disturbing front-seat
passengers. When headphones are in use, front-seat passengers
can use the vehicle’s audio system as usual through the car
speakers by pressing the SPEAKER button until “Headphone Sound
Only” appears on the screen.
The system comes with wireless IR headphones that receive a signal
from an IR transmitter concealed in the frame around the display.
Power LED
Volume Power ON/OFF
To turn the headphones on and off, push the Power ON/OFF button
on the right ear piece. The Power LED on the left ear piece indicates
when headphone power is on. Power turns off automatically after
three minutes of no audio to preserve battery life.
To adjust the headphone volume,rotate the thumb wheel switch on
the headphones.
The wireless IR headphones require two AAA batteries. To replace
the batteries, remove the battery compartment cap on the right
earpiece and insert batteries, as shown.

WATCHING BROADCASTTELEVISION
(ON TV TUNER-EQUIPPED SYSTEMS)
You can watch television or videotapes on the A7 if you have
installed the optional AC3105 TV Tuner or R5000-series VCP, and the
AC3024 TV/VCP harness (not included).
Note: Broadcast television reception varies with location,
terrain, distance from the broadcast tower, and other factors.
Signal quality is likely to vary in a moving vehicle.
1 Press SOURCE to select the “TV Tuner” input. “TV Tuner” and a
channel number (for example, “2”) will appear on the screen.
2 Press the UP CH and DOWN CH arrow buttons on the remote to
change channels. You can also use the UP and DOWN arrows on
the front control panel.
3 To scan all available channels, press SOURCE MENU.
Note: To watch broadcast television or videotapes in their
original format, press the DISPLAY MODE button on the
remote control until “Standard” is displayed on the screen.
This will properly size the image, instead of stretching the
image across the A7 wide screen. In “Standard” mode, you
will see black bars on the sides of the image, like this:
LISTENINGOVER THE CAR SPEAKERS
The A7 uses an FM Modulator to send audio through the vehicle radio
and thus through the speakers. To listen to A7 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 A7 MUTE is off. Tune to FM
frequency 87.9. If no A7 audio is heard, try tuning in 88.3.
To turn off A7 system audio over the car speakers, press SPEAKER.
“Headphone Sound Only” appears on the screen. Audio from the A7
system is then heard only over the headphones.
The A7 remembers which mode you have selected, and will return to
that mode each time the system is turned on. You may want 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 A7 is
not in use, close the A7 monitor, and both the A7 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.

17
Rosen Entertainment Systems
USINGGAMESAND CAMCORDERS
You may use video games, camcorders, and other portable video
units by connecting the unit to the auxiliary RCA input cables of the
A7. Check with your Rosen authorized dealer for the location of
these RCA jacks.
Red—Right channel audio input
White—Left channel audio input
Yellow—Video input
Press SOURCE to select the “Auxiliary Input”.
To use a game system, a 12VDC to 110VAC power inverter, available
at most electronic retail stores, is often required.
Note: If you want to watch non-widescreen, 4:3 images, press
the DISPLAY MODE button on the remote control until
“Standard” is displayed on the screen. This will properly size
the image, instead of stretching the image across the A7 wide
screen. In “Standard” mode, you will see black bars on the
sides of the image, like this:
OPTIONALROSEN ACCESSORIES FOR YOUR A7
The following Rosen acessories are available for your A7. Most of
these require some installation parts and labor - check with your
authorized Rosen dealer for details.
AC3105 TV Tuner
The AC3105 TV Tuner receives VHF and UHF television broadcasts.
It requires a TV antenna (not included). When installed using the A7
TV/VCP Harness (AC3024, not included), the AC3105 is controlled by
the A7 remote control.
R5000-series Videocassette Player
The R5000 series of videocassette players play VHS videotapes.
When connected to the A7 using the AC3024 harness (not included),
the VCP is controlled by the A7 remote control. When using the VCP,
thePLAY,PAUSE, EJECT,FORWARD,REVERSE,SOURCEMENU,
and INFO buttons all operate the VCP. For more information, see the
VCP Owner’s Manual.
CV7200 add-on second display screen for A7
You can add a matching 7” wide screen display to your A7. This
second screen can be used in a third row of seats, or the A7 and the
CV7200 can be installed side-by-side. While almost any monitor can
be used with your A7, only the CV7200 completely integrates
functionally and visually with the A7 system. This makes using your
A7 and CV7200 together truly seamless.
AC3003 Infrared Wireless Headphones
AC3205 Remote Control
Additional headphones and remotes are available from your autho-
rized Rosen dealer.

Rosen A7 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 such as
Cinemascope and Panavision became
popular, new aspect ratios were used
for them - 1.78:1, 2.35:1, and even 2.4:1.
When high-definition television was
developed, a screen shape with an aspect
ratio of 16:9, or 1.85:1, was selected as the
best compromise for viewing widescreen
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.
Your A7 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 your A7 display:
1) You are watching a widescreen movie with an aspect ratio
greater than 1.85:1. (For more options on dealing with this, see
below). Check the disc jewel box to determine the DVD’s aspect
ratio.
2) The DVD section of the A7 has been set for a 4:3 display instead
of a 16:9 wide display. See the next page for how 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 widescreen displays.
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.
WHAT CAN I DO?
First, Rosen recommends that for best results you use DVD’s that
say “anamorphic” or “enhanced for widescreen televisions” on the
box . However, your A7 can get rid of black bars with just about any
DVD using Rosen’s exclusive image-sizing features, explained below.
Only Rosen gives you so many wide-screen-filling options!

Make sure that the A7 internal DVD player is set to “WIDE”
(see DVD Setup, page 20).
Use the Display Mode button to select “Wide” or “Stretch”.
•To view widescreen DVD’s, use “Wide”.
•To stretch the picture to take up more of the screen, use“Stretch”.
•To zoom the picture, use the “Zoom” mode.
Note: for best results when zooming in on DVD images, use
the Disc Zoom feature below instead of the “Zoom” Display
Mode.
Finally, use the Disc Zoom feature to completely fill the
screen.
1 Press the DISC ZOOM button during playback to select among
the following options: x1.5, x2, and x4.
2 Press the arrow buttons to shift the magnified image left and right.
Note: To watch “fullscreen” DVD’s or broadcast television (using
an optional TV tuner), you can use the DISPLAY MODE button to
select “Standard”. This will properly size the image, instead of
stretching the image across the wide screen. In “Standard” mode,
you will see black bars on the sides of the image, like this:

The Digital Output Setting
There is a setting in the menu for a
Digital Audio output. The A7 does not
have a digital audio output. Leave this
setting in the “Analog” mode.
Note: Enabling the Digital Audio
mode disables the analog audio
output used by the FM Modulator
and the IR headphones, and can
resemble a system audio failure.
