Remote Sensors

The VOH681A incorporates two infrared sensors

which relay signals from any infrared remote control

to allow a remote mounted device to be controlled

simply by pointing its remote control at the remote

sensoreye mounted onthepod. This providescontrol

of auxiliary equipment such as Video Cassette and

DVDplayers. The infrared sensors can relay signals

from any manufacturer’s remote control to its

respective component connected to the AV1 or AV2

inputs.

External Auxiliary A/V Stereo inputs (Aux )

These inputs are provided to facilitate the temporary

connection of optional audio / video equipment, such

as a camcorder or video game system. They can be

accessed by removing their protective plastic cover

located behind the LCD hinge. To play a source with

theseinputs, useRCApatch cordtoconnect theaudio

/ video signals to their respective jacks. Mono audio

sources will require the use of an RCA Y cable (PN

0892165)to connecttobothrightand leftinputs. Once

theconnectionshavebeenmade,turntheVOH681A

on and press the source selector button on the pod

until the “AUX” indicator LED illuminates. The unit

will now play the audio and video signals from the

Optional Accessories

Wired Headphones

There is one 1/8” headphone jack on the VOH681A

thatcan beusedwith anystandardstereo headphone.

This jack is controlled by the volume up / down

buttons on the VOH681A or the remote control.

Remove and save the protective plastic cover to

access the jack. Remember to replace the cover

when the jack is not in use.

Wireless Headphones

The VOH681A 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

Wired FM Modulator

Your video system may be equipped with an RF

modulator, that allows you to listen totheVOH681A’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.

Audiovox Video Cassette Player (AV1)

In most installations a VCP will be connected to the

“AV1” input. To view a video cassette, turn the

VOH681A On and press the source button on its

control pad until the “AV1” indicator LED illuminates.

The VCP may also be operated with a remote or the

buttons on its face. The VOH681A is now ready to

play the audio and video signals from the VCP if it is

connectedtothe “AV1” input. Inserting a tapeintothe

VCP will automaticly turn it on and 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.
