<P>PROBLEM TO BE SOLVED: To easily search for the place where the highest electric field intensity level is obtained within a limited range if a mobile telephone terminal is in an inferior radio wave state. <P>SOLUTION: An electric field intensity detection part 21 in a radio part 2 detects an electric field intensity level. A signal generation part 3 generates a signal for giving notice of the electric field intensity level detected by the electric field intensity detector 21. A speaker 4 outputs the electric field intensity level in the form of a sound and an LCD 5 visually displays the electric field intensity level. A memory 6 stores a program for mobile telephone terminal operation, a reference electric field intensity level, and an electric field intensity level detected during movement. A center control unit 7 reads both the electric field intensity levels out of the memory 6, compares them with each other, and gives notice of the comparison result to the speaker 4 or LCD 5 through sound volume or display. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
