A transceiver, which is capable of being used even in a severe situation such as situations in salvage operations and the like in which the transceiver is often submerged, is composed of: a PTT switch for transmitting an audio signal upon depression of the switch; a sound input/output portion for inputting and outputting a sound; and a main body portion for transmission and reception of a radio signal. All of the above components except the main body portion are formed into independent and connecting cables are provided between the independent units and the main body.
