(See below, Weak channel installation) • Once you have searched for as well the available Antenna as well as the Cable TV channels, they are stored in the memory. 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. Important: After the installation of the TV channels has been done, always make a selection in the Installation menu between Antenna or Cable whether you want to watch Antenna TV channels or Cable TV channels. If you make use of a signal splitter do not forget to put the switch in the corresponding position. 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. Weak channel installation This enables you to do a weak ATSC digital channel installation.This is only available for TV channels installed via an antenna connection (see p. 6). & Select a channel in the channel list (in the antenna mode). é The signal strength is displayed and updated continuously as you rotate the antenna. 15
