Abstract

PURPOSE:To expand the usable range of a satellite broadcast receiver by providing a manual channel selection key, a frequency input ten-key, a frequency fine adjustment key, a memory key for inputted frequency and an input key for preset channel as operation keys. CONSTITUTION:In the case of manual preset, at first a manual channel selection key 23 in operation keys 17 is depressed, and when an object frequency and channel is unregistered, the frequency is entered by a 10-key, fine adjustment UP or DOWN keys 25, 26 are used for fine adjustment while observing the screen and a channel number corresponding to the frequency is inputted. The preset operation as above is implemented while observing a display device 18. Then a memory key 27 is depressed to store the frequency and the channel, and when a set channel is selected, the same display is implemented and the control by tuning of a tuner section 4 is taken. Thus, even when a satellite is newly launched, an object channel and frequency is present in the case of receptible range and the usable range of the satellite broadcast receiver are expanded.
