Output video images on your Joybook to a TV or AV device that has an
S-Video Input socket by connecting it to the S-Video Out socket on your
Joybook.
Unless you intend to use the sound reproduction output of the built-in
Joybook speakers, you will also need to separately connect the Joybook
audio output socket to an appropriate sound reproduction device.
Connect a DVB-T type TV antenna to the RF socket (available on
selected models) to enjoy the digital TV feature.
Only use the specific TV antenna provided with your Joybook to connect
to the built-in TV Tuner card.
