Memorizing the Channels

This eliminates the need to change channels by entering the channel digits. There are three steps for memorizing channels: selecting a broadcast source, memorizing the channels (automatic) and adding and deleting channels (Channel Lists).

2. Press the ▲ or ▼ button to select Auto Program, then press the ENTER button.
3. Press the ▲ or ▼ button to select an antenna connection, then press the ENTER button.
