Connecting the RF (Antenna) to another device
To ensure you receive all available channels on
your Optus TV Set Top Box, the TV antenna cable
should be connected from the antenna wall
socket to the ANT-IN socket on the Set Top Box.
To pass the antenna's signal to another device
(eg, DVD player or VCR), attach the antenna cable
provided with the Set Top Box to the ANT-OUT
socket on the Set Top Box and the other end into
the ANT-IN (or RF-IN) socket on the other device.
Then connect the TV to the other device by
plugging another antenna cable into the ANT-OUT
(or RF-OUT) socket on that device and the other
end into the ANT-IN (or RF-IN) socket on the TV.
Connecting to a Home Theatre (Digital Audio)
Your Set Top Box has both coaxial and optical
digital audio outputs (these cables are not
supplied with the Set Top Box but can be
purchased from any electronics store). Either
of these can be used to connect to your home
theatre so you can enjoy various surround
sound modes. Refer to your home theatre
supplier for more details.
While digital sound is unaffected by the volume
control setting on the Set Top Box, it will mute
when commanded through the remote control.
Please note that Optus TV Customer Care
provides support for the Set Top Box connected
directly to a TV, and does not support additional
audio-visual devices.
