PURPOSE:To facilitate tracing from a radio base station or the like by providing a power supply connection circuit controlling the power connection to a part of circuit when a specific control signal from the radio base station is received even if a main power switch is turned off. CONSTITUTION:When the 1st specific control signal is received from the radio base station while a main power switch 8 is turned on, the power connection not through the main power switch 8 but through a make contact rl is formed to a reception section 3, a transmission section 4 and a transmission/reception control section 5. When the operator turns on the main power switch 8, a display device of an operation section 6 is turned off and the operating function is stopped, but the control signal required for the mobile radio terminal equipment is supplied in the radio base station. Then the mobile radio terminal equipment is traced easily by utilizing the sent radio wave. Further, in receiving the 2nd specific control signal from the radio base station, a power connection relay RL is released and all power supplies in the terminal equipment are opened, but when the operator turns on the main power switch 8 again, the equipment is used normally without any change. |
