1. A radio communication apparatus comprising:
- recognizing means for recognizing power input from an outside power source to said radio communication apparatus; and
control means for automatically setting up a hands-free communication mode when said recognizing means recognizes the power input from the outside power source, said hands-free mode being a mode in which an amplification level is adjusted based on one of a received speech level and a transmitted speech level.

Abstract
A communication apparatus of the present invention has a hands-free communication capability and is applicable to, but not limited to, a motor vehicle. Only if the apparatus is connected to, e.g., an on-board cigar-lighter, hands-free communication can be held. This eliminates the need for a hands-free unit, an outside microphone and other extra parts conventionally mounted on the vehicle to implement a hands-free feature.

8. A radio communication apparatus comprising:
-
recognizing means for recognizing power input from an outside power source to said radio communication apparatus; amplifying means for amplifying a speech; outputting means for outputting a speech level amplified by said amplifying means; control means for controlling a speech amplification degree of said amplifying means on the basis of the speech level when said recognizing means recognizes the power input from the outside power source; and setting means for setting up a function of automatically answering a call incoming when said recognizing means recognizes the power input from the outside power source. - View Dependent Claims (9, 10, 11, 12, 13)

14. A radio communication apparatus comprising:
-
recognizing means for recognizing power input from an outside power source to said radio communication apparatus; first amplifying means for amplifying a received speech; second amplifying means for amplifying a speech to be transmitted; first outputting means for outputting a receipt speech level amplified by said first amplifying means; second outputting means for outputting a transmission speech level amplified by said second amplifying means; control means for reducing, after said recognizing means has recognized the power input from the outside power source, a speech amplification degree of said second amplifying means relatively when the receipt speech level rises, said control means further for reducing, after said recognizing means has recognized the power input from the outside power source, a speech amplification degree of said first amplifying means relatively when the transmission speech level rises; and setting means for setting up a function of automatically answering a call incoming when said recognizing means recognizes the power input from the outside power source. - View Dependent Claims (15, 16, 17, 18, 19)

20. A radio communication apparatus comprising:
-
recognizing means for recognizing power input from an outside power source to said radio communication apparatus; first amplifying means for amplifying a speech; second amplifying means for amplifying a speech with a higher amplification degree than said first amplifying means; decision means for determining whether a speech is output; control means for causing, when said recognizing means recognizes the power input from the outside power source, said second amplifying means to control a speech amplifying degree on the basis of a result of said decision means and based on a speech level of said speech being output; and setting means for setting up a function of automatically answering a call incoming when said recognizing means recognizes the power input from the outside power source. - View Dependent Claims (21, 22, 23, 24)

25. A radio communication apparatus comprising:
-
recognizing means for recognizing power input from an outside power source to said radio communication apparatus; first amplifying means for amplifying a received speech; second amplifying means for amplifying a speech to be transmitted; third amplifying means for amplifying the received speech with a higher amplification degree than said first amplifying means; fourth amplifying means for amplifying the speech to be transmitted with a higher amplification degree than said second amplifying means; decision means for determining whether a received speech is output; control means for causing, after said recognizing means has recognized the power input from the outside power source, said first amplifying means and said third amplifying means to amplify the received speech when said decision means determines that said received speech is output, said control means further for causing, after said recognizing means has recognized the power input from the outside power source, said second amplifying means and said fourth amplifying means to amplify the speech to be transmitted when said decision means determines that a received speech is not output; and setting means for setting up a function of automatically answering a call incoming when said recognizing means recognizes the power input from the outside power source. - View Dependent Claims (26, 27, 28, 29, 30)
