Normally, when the mobile radio is in use, the power switch 2 is connected to "ON" and the power of the battery 1 is supplied to each circuit power through the transistor 12. At this time, the voltage monitor 3 detects the voltage of the battery 1 and operates to turn on the transistor 12 because the battery voltage is equal to or higher than the set voltage Va2. If the battery 1 is used for a long time in this state, the battery 1 is consumed, and the battery voltage becomes Va1 (ta1 time) in FIG. The voltage monitor 3 detects that the voltage Va1 has been reached, and transmits this to the control circuit 6. As a result, the control circuit 6 issues a battery consumption warning (ta1 to ta2 hours). If the mobile radio is continuously used in this state, the voltage becomes Va2 (t
At time a2), this voltage is detected by the voltage monitor 3, the transistor 12 is turned off, the power supply to each circuit power supply is stopped, and the operation of the mobile radio device is stopped. In this state, power is not supplied to each circuit power supply, and outgoing / incoming calls and telephone calls cannot be made. However, in this state, if the power switch 2 is set to the emergency “SUB-BT” side, the remaining capacity of the battery 1 becomes operable for the period from ta2 to tb2 shown in FIG.
You can make and receive calls and talk. Then, the battery 1 is further used and the battery voltage is Vb1 (t
At the time of b1, this is transmitted to the control circuit 6 by the voltage monitor 7 and the battery consumption warning (tb1
Ttb2 hours). Here, when the battery 1 is further used, the voltage monitor 7 detects this when the voltage drops to the voltage Vb2 (at tb2), that is, when the voltage of the battery 1 becomes the minimum operating voltage of the mobile wireless device. The detection is transmitted to the control circuit 6 and the control circuit 6 is reset.
Control signals are applied to the switches 8 and 9 through the switches 3 and 14, the switches 8 and 9 are turned off, the power supply to the receiver 9 and the transmitter 11 is stopped, and the mobile radio becomes inoperable.

The receiver 9 of the mobile radio performs an intermittent reception operation during standby. However, as described above, the voltage of the battery 1 becomes Va2 (at ta2), and this is monitored by the voltage monitor 3. If the operation of sending / receiving and talking of the mobile radio device once stopped due to the detection is restarted by setting the power switch 2 to the emergency “SUB-BT”, the restarted sending / receiving and calling are resumed. Call behavior
Until the voltage of the battery 1 drops to the voltage Vb2 (at tb2) and this is detected by the voltage monitor 7, that is, until it is detected that the voltage of the battery 1 has become the minimum operating voltage of the mobile radio. May stop the intermittent reception operation and perform only the transmission operation. In this case, when the power switch 2 is set to the emergency “SUB-BT”, a control signal (not shown) is sent to the control circuit 6 in conjunction with this, and
As a result, the control circuit 6 stops the intermittent reception operation of the receiver 9, controls the consumption of the battery 1, and controls so that only the transmission operation by the transmitter 11 can be performed. When the transmitting operation is performed by the transmitter 11 and the base station receives the transmission and a call is made between the mobile radio and the base station, the receiver 9 of the mobile radio, of course, performs the normal reception. Perform the operation.
