our remote has an A/CH (Alternate Channel) button. Pressing this button will toggle between the Current and one previously selected channel.
Press the CH + or CH � button (or the Numbered buttons) to select a channel to view. Then using the same buttons select a second channel to view. Press the A/CH button repeatedly to toggle between the two channels.

This is a great feature to toggle between two programs that your interested in watching at the same time. Remember, the A/CH will only toggle the current channel and the last previsouly viewed channel.
