A control block recognizes the other party of the telephone call when both calling
and called case. When the user operates the reservation melody key of the key input
block while talking over the telephone and the telephone call reservation is directed,
the control block retrieves telephone/E-mail memory and judges for the calling
melody number whether to be registered. Because calling melody number 1 is registered,
music data 1 is read, and the mute is put so that the voice from mike is not transmitted.
When the control block outputs music data 1 to melody generation block, the melody
generation block generates the calling melody signal based on music data 1, and
transmits it to the other party of the telephone call via modem, sending and receiving
block and antenna. Moreover, the control block always observes the control channel
specified by the base station while waiting. When detecting the arrival of a call
and "4" of the calling melody specification data, the control block judges for
caller information transmitted at the same time whether to be registered in telephone/E-mail
memory. In this case, the control block displays the caller number and Hanako Yamada
of the name because it is registered in memory number 1. In addition, because the
calling melody specification data is "4", "Good news" of the character data corresponding
to it is displayed, and "Beautiful Sunday" of music data 4 registered in memory
number 4 is performed as a calling melody.
