Remote Sensor
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.
Accessories
Wireless Headphones
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.
See the documentation
accompanying your Audiovox wireless headphones.
