Important Notice
It is unlawful in most jurisdictions for a person to drive a
motor vehicle which is equipped with a television viewer
or screen that is located in the motor vehicle at any point
forward of the back of the driver’s seat, or that is visible,
directly or indirectly, to the driver while operating the
vehicle. In the interest of safety, the VOH702 should
never be installed where it will be visible, directly or
indirectly, by the operator of the motor vehicle.
Please note that the state of Rhode Island forbids the
installation of such a device in a motor vehicle.
Television Reception
This entertainment system is designed primarily for
viewing pre-recorded movies or playing video games.
Television reception in a moving vehicle will be
limited and in some areas will not be possible due to
weak and variable signal strength. Television
viewing in a stationary vehicle will result in an
improvement, but may still be marginal due to
strength. The quality of the picture will not be
consistent with home TV reception. Reception may
be affected by the weather and distance from the TV
station. A weak signal may cause the picture to roll,
be snowy, or cause some color loss.

Congratulations on your purchase of the Audiovox
VOH702 drop down TV/Video monitor. The VOH702
has been designed to give you and your family many
years of video entertainment in the mobile environment.
Please read the directions that follow to familiarize
yourself with the product and to ensure that you obtain
the best results from your equipment. Please note:
Installation options vary, see the individual owner’s
manuals for each component in your system to obtain
a full understanding of each component’s operation.
Safety Precaution
For safety reasons, when changing video tapes it is
recommended that the vehicle is not in motion, and that
you do not allow children to unfasten seat belts to
change tapes or make adjustments to the system.
System adjustments can be accomplished using the
remote control unit, while seat belts remain fastened.
Enjoy your Audiovox entertainment system but
remember- safety of all passengers remains the
number one priority.

OPERATION
Overhead Dome Lights
The lights integrated into the VOH702 are controlled by
a three position slide switch. Sliding the switch to the
on position will turn the lights on. The off position will
prevent the lights from turning on at all times, and the
auto position will allow the lights to turn on and off with
the vehicle’s interior lighting. Do not leave the vehicle
unattended with the dome light switch in the on position,
as this could result in a discharged battery.
The switch is shown in the center position. See page 5
for more details.
Light Switch
Screen Release
Remote Sensor
The VOH702 incorporates an infrared sensor, which
relays the signals from the remote control to allow the
VOH702 and VCP to be controlled simply by pointing
it’s remote control at the remote sensor. This provides
control of auxiliary equipment such as an Audiovox
Video Cassette Player. The infrared sensor can relay
signals from any manufacturer’s remote control to it’s
respective component connected to the Video 1 and 2
inputs, such as a DVD player. In this case you must
use the remote control supplied with the DVD player.

External Auxiliary A/V Stereo Inputs (Aux
Video 2)
These inputs are provided to facilitate the temporary
connection of optional audio/video equipment, such as
a camcorder or video game system. To play a source
with these inputs, an RCA patch cord is required to
connect the audio / video signals to their respective
j
acks. Mono audio sources will require the use of an
RCA Y-cable (P/N 0892165) to connect to both right
and left inputs, if patch cords are installed into the
AUX inputs, the AUX INPUT 2 will be temporarily
bypassed. Once the connections have been made,
turn the VOH702 on and press the source button on
the VOH702 or the TV / Video button on the remote
control until “Video 2” is displayed on the screen. The
unit will now play the audio and video signals from the
accessory connected. The remote control will not
operate the accessory components.
VOH702 Jack Panel
OPTIONAL ACCESSORIES
Wired Headphones
There are two 1/8” headphone jacks on the VOH702
that can be used with any standard stereo
headphones. These jacks are controlled by the
volume up/down buttons on the VOH702 or the
remote control.
Wireless Headphones
The VOH702 includes a RF transmitter
(P/N WTXRF01) for use with optional Audiovox
wireless headphones. Tuning the headphone switch
on, and wearing them activates the internal micro
switch, (which includes a tuning knob to tune into the
preset frequency on the RF transmitter), which will
activate the internal RF receiver and the volume can
be adjusted separately with the controls on the
headset. See the documentation accompanying your
Audiovox wireless headphones.

-12-
Wired FM Modulator (P/N 0190730)
Your video system may be equipped with an RF
modulator, that allows you to listen to the VOH702’s
audio signal by tuning your vehicle’s radio to the
selected frequency, (88.7 or 89.1- check with your
installer) and tuning on the remote mounted RF
modulator switch. (In most cases this toggle switch
will be located underneath the driver’s side of the
dash, check with your installer for the exact location.)
Whenever the RF modulator is on, broadcast radio
reception will be poor. Turning the remote mounted
toggle switch off will allow for normal radio reception.
Video Output
The VOH702 provides a video output for an optional
video monitor(s). This output will provide a video
signal that duplicates the signal displayed by the
VOH702 to an additional monitor or video display.
Please see your installer for more information.
Audiovox Video Cassette Player (Aux
Video 1)
In most installations a VCP will be connected to the
“Video 1” input. To view a video cassette, turn the
AVP7000/ AVP7285 on and press the source button
on its control panel or the TV/Video button on the
remote control unit until “Video 1” is displayed on the
screen. The VCP may also be operated with the
remote or the buttons on its face. Inserting a tape
into the VCP will turn it on and automatically activate
the play mode. If a rewound tape had been loaded
into the VCP, prior to its activation press play on the
VCP or the remote control to view the tape. For
more information see the owner’s manual
accompanying your VCP.

Troubleshooting
PROBLEM SOLUTION
Poor TV Reception •Perform auto programming of
the tuner
•Verify antenna condition.
•NOTE: Due to the nature of TV
signals, vehicle motion,
direction the vehicle is facing,
distance from the transmitter,
nearby surroundings and
weather may adversely affect
TV reception. These
conditions may result in the
following: picture roll, “snowy”
picture, or momentary loss of
color. Please refer to page 2
for more information on TV
reception.
Poor radio reception (FM
modulator installed) •Check the condition of the
vehicle’s radio antenna.
•Verify that the antenna is fully
raised
•If a wired RF modulator has
been installed, verify that it’s
switch is turned to the off
position
IR sensor inoperative •Verify that the batteries in the
remote are fresh
•Verify that the remote eye is
not obstructed.
•Verify that the infrared
transmitter is affixed over the
sensor eye of the component
to be controlled
