Abstract

PURPOSE:To obtain a display function with less consumption of a power supply and excellent operability in the radio selective calling receiver. CONSTITUTION:When general information is displayed on a display section 17 in the lighting state and an operation switch 24 is operated again, a decoder 22 informs it to a CPU 23a. Thus, when the operation switch 24 is operated consecutively twice, the CPU 23a reads message information from a RAM 23c and displays it on the display section 17. The decoder 22 drives a lighting section 18 and counts a predetermined time and when the operation switch 24 is not operated, the time count is expired to turn off the lighting section 18. When the operation switch 24 is operated while message information is displayed on the display section 17, the CPU 23a switches the display information from message information into general information in response to the operation notice from the decoder 22 and the decoder 22 turns off the lighting section 18. Moreover, when the operation switch 24 is not operated for a predetermined time, the CPU 23a allows the decoder 22 to turn off the lighting section 18 in response to the time-up notice from the decoder 22.
