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   External   Auxiliary   headphones.   ON   OFF AUTO   A/V Stereo   Inputs   O N O F F A U T O OP Infrared   Transmitter   Wired FM Modulator   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 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.   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.   Troubleshooting   Replacement Parts   PROBLEM   SOLUTION   Remote Control   1361612   1023336   Poor TV reception • Perform auto programming of the tuner.   • Verify antenna condition.   External Input Cover   • 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.
