Operation
Overhead Dome Lights
Remote Sensor
The VOH682 incorporates an Infrared sensor which
relays signals from the remote control to allow the
VOH682 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 any manufacturer’s remote
control to its 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.
The lights integrated into the VOH682 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.

Optional Accessories
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, remove and save the
protective plastic cover to access the inputs. Remember
to replace the cover when the jacks are not in use. RCA
patch cord is required to connect the audio / video
signals to their respective jacks. Mono audio sources
will require the use of an RCA Y cable (PN 0892165)
to connect to both right and left inputs. Whenever, a
video source is connected to these inputs, the
equipment installed to the Aux Video 2 input will be
bypassed. Once the connections have been made,
turn the VOH682 on and press the source button on
the VOH682 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 infrared sensor will not
operate with components connected to these inputs.
Wired Headphones
There are two 1/8” headphone jacks on the VOH682
that can be used with any standard stereo
headphones. These jacks are controlled by the
volume up / down buttons on the VOH682 or the
remote control. Remove and save the protective
plastic cover to access the jacks. Remember to
replace the cover when the jacks are not in use
Wireless Headphones
The VOH682 includes a built in infrared transmitter
for use with Audiovox wireless headphones (PN
MVSWHS). Turning the headphone switch on, and
wearing them activates the internal micro switch
which will activate the internal IR receiver and the
volume can then be adjusted separately with the
controls on each headset. Any number of wireless
headphones can be used, but all must be within a line
of sight from the transmitter, as infrared
transmissions, like visible light travel only in a straight
line. See the documentation accompanying your
Audiovox wireless

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
VOH682 On and press the source button on its control
panel or the TV / Video button on the remote control
until “Video 1” is displayed on the screen. The VCP
may also be operated with the remote or the buttons
on its face. The VOH682 is now ready to play the
audio and video signals from the VCP if it is connected
to the “Video 1” input. Inserting a tape into the VCP
will turn it on and automatically activate the play mode.
If a rewound tape had already been loaded into the
VCP, prior to its activation press play on the VCP or
on the remote control to view the tape. For more
information see the operator’s manual accompanying
your VCP.
Your video system may be equipped with an RF
modulator, that allows you to listen to the VOH682’s
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 will be poor. Turning the remote mounted
toggle switch off will allow normal radio reception.
Video Output
The VOH682 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 VOH682 to an additional monitor or video display.
Please see your installer for more information.
Warnings
v Do not use any solvents or cleaning materials
when cleaning the video system.
Aux Video 2
The second video input may be connected to a DVD
player, video game system, or other audio / video input.
To play the Video 2 source, turn the VOH682 on and
press the source button on the VOH682 or the TV /
Video button on the remote control until “Video 2” is
displayed on the screen. Turn the source component
on with its power button or remote control. The
VOH682 is now ready to play the audio and video
signals from the source connected to video 2 inputs.
Remember, the equipment connected to this input will
be bypassed whenever the External Auxiliary A/V
Stereo inputs are used. Please refer to the external
auxiliary input section for more detailed information.
v Do not use any abrasive cleaners, they may
scratch the screen. Use only a lightly dampened
lint free cloth to wipe the screen if it is dirty.
v Lock the LCD screen in the fully closed position
when not in use.
v Before putting on headphones always adjust the
volume setting to the lowest position.
v Remember to leave the dome light switch in the
off or auto positions when the vehicle is
unattended, as the dome lights, if left on, can drain
the vehicle’s battery.
v Do not put pressure on the screen.
v Caution children to avoid touching or scratching
the screen, as it may become dirty or damaged.
