This superior 19" Diagonal Television has a countdown timer that returns TV to original channel, so other channels can be browsed during program breaks. Auto Cable/Air Switch sets tuner to cable or "off-air" frequencies during initial setup. Then system automatically scans for and locks active channels into channel memory. Assign up to four on-screen characters to easily identify channels (such as NBC, HBO, ESPN, VH-1). On-screen displays make it easy to adjust most picture, sound, and convenience features from either the remote control or the TV front panel buttons.
