Abstract

PURPOSE:To display individual display, group display and emergency display with distinction without increasing the number of display device by providing a display device for the group display in addition to an individual calling display device connected individually to each slave set and using the display device for the group display in common for a display for emergency calling. CONSTITUTION:When a calling switch S1 of a slave device is turned on, a display device L1 is lighted, a transistor (TR) Q1 is turned on at the same time, and an oscillating circuit OSC1 is oscillated in frequency f1. Then, TRQ4, TRQ5 repeat turning on/off in the frequency f1 and the calling display L0 for group and emergent calling repeats flickering in the frequency f1. When a switch T for emergency is turned on, TRs Q2, Q3 are turned on, and the oscillation of the OSC1 is stopped. Further, the input side of an OSC2 goes to high level, and the OSC2 oscillates in the frequency f2. Then, TRs Q4, Q5 repeat turning on/off in the frequency f2, and the calling display device L0 for group and emergent calling repeats flickering in the frequency f2.
