摘要： A method for performing a preset listening operation for a radio broadcast using a microcomputer including a first tuner, a second tuner, a random access memory and a timer. The microcomputer stores data regarding a preset channel, a preset listening start time and a preset listening end time in the random access memory. If a main power is turned on, the microcomputer tunes the first tuner to an initial channel to listen to a general broadcasting program. The microcomputer then checks whether a preset listening function has been selected. If the preset listening function has been selected, the microcomputer detects the data from the random access memory. The microcomputer identifies the present time based on an output of the timer and then determines whether the checked present time is the same as the preset listening start time. If the present time is the same as the preset listening start time, the microcomputer turns off the first tuner and tunes a second tuner to the preset channel to listen to a preset broadcasting program. The microcomputer then identifies the present time based on the output of the timer and then determines whether the checked present time is the same as the preset listening end time. If the identified present time is the same as the preset listening end time, the microcomputer turns off the second tuner and tunes the first tuner to the initial channel to listen to the general broadcasting program.
