<p>PROBLEM TO BE SOLVED: To provide a communication apparatus capable of allowing search sound that is to be output to search a misplaced apparatus to be output by appropriate sound volume.SOLUTION: When a distance between a portable terminal 10 and a speaker unit 20 becomes a fixed distance or more so as to output alarm sound from a speaker 11 of the portable terminal 10, a user is urged to perform an operation by allowing a display part 14 of the portable terminal 10 to display a picture to determine sound volume to output search sound from a speaker 21 of the speaker unit 20. For example, an inquiry is made to a user about whether the sound can be output at the "low" level of output sound volume or not. When the user operates a key to accept the appropriate output sound level corresponding to "low", sound information to allow search sound to be output from the speaker 21 at the output volume level corresponding to "low" is transmitted to the speaker unit 20.</p> |
