Operation  
1. Sliding the screen release lock forward will  
unlock the LCD screen and it will drop down  
slightly. Pivot the screen downward until a  
comfortable viewing angle is reached. The  
internal friction will hold the screen in position  
while the system is in use.

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.  
3. After the unit has been turned on and is displaying  
a picture, adjust the viewing angle, by pivoting  
the screen to optimize the picture quality.  
4. Remember to turn the unit off and pivot the LCD

Remote Sensor  
Accessories  
Wireless Headphones  
The VOH683 incorporates an Infrared sensor which  
relays signals from the remote control to allow the  
VOH683 and VCP to be controlled simply by pointing  
its remote control at the remote sensor eye. This  
provides control of auxiliary equipment such as an  
Audiovox Video Cassette Player. The infrared sensor  
can relay signals from most manufacturer’s remote  
controls to the 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.  
The VOH683 includes a built-in dual channel infrared  
transmitter for use with Audiovox wireless  
headphones (Part Number IR2CHS - Dual Channel).  
The volume can then be adjusted with the controls  
on each headset. The wireless headphones must  
be used within a line of sight from the transmitter, as  
infrared transmissions, like visible light travel only in  
a straight line.

Wired FM Modulator  
NOTE: This equipment has been tested and found  
to comply with the limits for a Class B digital device,  
pursuant to Part 15 of the FCC Rules. These limits  
are designed to provide reasonable protection  
against harmful interference in a residential  
installation. This equipment generates, uses and  
radiate radio frequency energy and, if not installed  
and used in accordance with the instructions, may  
cause harmful interference to radio  
communications.  
Your video system may be equipped with an RF  
modulator that allows you to listen to the VOH683’s  
video audio signal by tuning your vehicle’s radio to the  
selected frequency, (88.7 or 89.1 - Check with your  
installer) and turning 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 of the vehicle’s radio will be diminished.  
Setting the remote mounted toggle switch off will allow  
normal radio reception.

S/N ratio : 60 dB  
Video Output  
Optional Accessories  
The VOH683 provides a video output for an optional  
video monitor(s). (Refer to page 7 of the installation  
guide for more details.) This output will provide a video  
signal that duplicates the signal displayed by the  
VOH683 to an additional monitor or video display.  
Please see your installer for more information.  
Wired Headphone  
There are two 1/8” headphone jacks on the VOH683  
that can be used with any standard stereo  
headphones. The jack, TV EAR, is used to listen to  
the video program audio. The audio volume is  
controlled by the TV VOLUME up/down buttons. The  
jack, RADIO EAR, is used to listen to the FM  
broadcast . The audio volume is controlled by the  
RADIO VOLUME up/down buttons.  
Remove the protective plastic cover to access the
