Abstract
In a portable radio equipment, a first power unit (11) and a second power unit (15) can be selectively mounted to or removed from a radio equipment main unit (1). The main unit contains a transmit audio circuit (3), a first microphone (4), and a power circuit (5). When the first power unit is mounted to the main unit, a short-circuiting member (12) in it connects the first microphone to the transmit audio circuit, and a power source (8A) in it provides power to the power circuit. When the second power unit (15) is mounted to the main unit (1), a second microphone (16) in it is connected to the transmit audio circuit to the main unit, and a power source (8B) provides power to the power circuit.
