Required Cables
1 Set of Video/
Stereo Audio Cables
Connect the Digital Cable Box’s
LINE OUT (TV) AUDIO/VIDEO jacks
to the TV’s AUDIO/VIDEO IN jacks.
Note: If your TV has an S-VIDEO jack:
For best picture quality, use an S-VIDEO
connection instead of the yellow video cable
on your combined A/V cable. Connect the
Digital Cable Box’s S-VIDEO OUT jack to the TV’s
S-VIDEO IN jack. S-VIDEO does not provide audio,
so audio cables must still be connected.
Connect one end of the AC power cord to the Digital Cable Box’s AC IN jack and plug the other end
into an AC outlet. Tune the TV to channel 3.
Setting up High-Definition TV (HDTV)
Your iO TV subscription includes free high definition service. With HD, you’ll see and hear programs like
never before with the ultimate picture solution and Dolby Digital 5.1 sound.
Picture Format and Aspect Ratios
Your HDTV Digital Cable Box has the ability to display video in four formats: 480i, 480p, 720p and 1080i,
and two aspect ratios: 16:9 and 4:3. The default picture format is 1080i with an aspect ratio of 16:9. If
your TV does not support 1080i, or you have a 4:3 HDTV, follow the steps below.
Warning: Do not change the picture format from the quick settings menu before testing the
formats with the HDTV setup wizard. If your TV is not compatible with the format you choose,
you will not be able to view any TV signal. If you have already chosen an incompatible format,
follow the steps on next page.
