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 drivers seat, or that is visible, directly or indirectly, to the driver while operating the vehicle. In the interest of safety, the VOH682 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 signal strength. The quality of the picture will not be consistent with home TV reception. Reception may be affected by weather & distance from T.V. station. A weak signal may cause the picture to roll, be snowy, or cause some color loss.

Turning the VOH682 On or Off
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 detent will hold the screen in position while the system is in use. 2 Pressing the power button on the pod or the remote will turn the system on or off alternately. When in use the internal backlighting will illuminate the controls. 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 to the locked position when not in use.

Operation

Overhead Dome Lights 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 vehicles 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. 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 manufacturers 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.

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. External Auxiliary A/V Stereo 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 headphones.

Infrared Transmitter

Wired FM Modulator Your video system may be equipped with an RF modulator, that allows you to listen to the VOH682s audio signal by tuning your vehicles 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 drivers 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.

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 operators manual accompanying your VCP.

Warnings

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 solvents or cleaning materials when cleaning the video system. 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 vehicles 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.

Troubleshooting

PROBLEM SOLUTION Poor TV reception Perform auto programming of the tuner. Verify antenna condition.
