Buy this 13" Diagonal Television which 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. On-screen displays make it easy to adjust most picture, sound, and convenience features from either the remote control or the TV front panel button. Convenient scheduling system can be used in a variety of ways: Sleep Timer. Automatically turns off the TV after a preset time period - for those times when you drift off to sleep in front of the television. Alarm Timer. Wake up to your favorite morning show or turn on your television automatically to catch your favorite program. Scheduling Timer. Since the alarm setting remains in the TV memory indefinitely, the TV can be scheduled to turn on at the same time every day.
