Abstract

PURPOSE: To prevent the watching from being stopped on the way of program, by displaying that the image reception possible time is less on the CRT screen, through the detection of the detection circuit when the voltage of battery reaches less than a given value in the range of TV reception possible.
CONSTITUTION: When the battery 1 voltage reaches less than a given value in the range of image reception possible of the TV receiver, detection is made with the detection circuit 45 in the range where the discharge prevention circuit 3 is not operated. Further, the output of the circuit 45 displays 46 that the remaining image reception possible time is less on the CRT screen. Thus, it is prevented on the way of program that the overdischarge prevention circuit 3 is rapidly operated and no watching is made.
