Note: Digital Channel selection delay
Due to the tuning complexity of subchannel digital
programming, the time to select and view a digital
channel may take slightly longer than what the viewer
is normally accustomed to (as compared to analog
channel programs).
Digital channel broadcasts contain program and
system data information that must be processed
before the channel selection can be displayed.
Channel tuning
Available channels:
- Cable (analog NTSC or digital QAM): max. from 1 to 135
- Terrestrial (analog NTSC or digital ATSC): max. from 2 to 69
If a tuned channel is not yet in the master channel map, the TV will attempt
to tune the channel and it will be added to the map.
If the channel is not acquired, a message will appear that the channel is not
available.
When you tune an audio-only digital subchannel, a display appears with the
message
Audio only .
Note: Subchannel selections
The new standards employed with digital broadcasting make it possible to receive
multiple program channels under a single major channel number which can be
selected by pressing the digit remote control direct-acces channel number entry.
