Abstract
Abstract The invention provides a program selection method and apparatus using a cordless telephone set by which a desired program can be selected from among a large number of programs rapidly with certainty and intuitively and directly. A TEL key changes over a mode of a cordless telephone set between a first mode in which the cordless telephone set is used as a telephone set and a second mode in which the cordless telephone set is used as a remote commander for remotely controlling an electronic apparatus. A monitor apparatus displays a first display corresponding to a function allocated to any of keys of the cordless telephone set in the first mode and a second display different from the first display and corresponding to another function allocated to any of the keys in the second mode for remotely controlling the electronic apparatus. A transmission circuit generates a signal corresponding to the manually operated key in response to a manual operation of any of the keys.
