PROBLEM TO BE SOLVED: To enable connection afterward by setting the mobile communication equipment to an outside the range mode at the time when an incoming tone rings or beforehand, without turning off the power of the mobile communication equipment. SOLUTION: A charging part for a transmitter provided with a weak radio wave transmission circuit 5 for making a transmission radio wave to the mobile communication equipment 2 outside the range is provided, the battery charging device 1 of the mobile communication equipment incorporates a PNP transistor for current detection to be an input switching power supply for AC/DC conversion or of an on-vehicle use for obtaining power from an outlet for a cigar lighter, the transmitter is operated by turning on a transmission switch, a transmitted feeble radio wave is made to be the outside the range by scanning the inside of the band of the operation frequency of corresponding mobile communication equipment to prevent the reception of a radio wave from a base station, the transmitter is provided with a changeover switch corresponding to conventional operation frequency and a CDMA-1 type operation frequency and can also use a disposable power supply including a dry battery.
