PURPOSE:To perform accurate information guidance easily without entailing any noise by voicing or displaying only necessary information for recognition. CONSTITUTION:A transmitter 1 installed in an information center has voice synthesizers 2 and modulators 3 which store voice information and synthesize and output the information in pairs, which are each in charge of one channel and provided as many as (n) channels. Modulated signals of those channels 1-(n) are put together in time series by a synthesizer 4, whose output is radiated from an antenna after power amplification. The information radiated from the transmitting antenna is received by the receiver 6 that a customer carries, a channel selecting circuit 7 performs channel selection, and a demodulating circuit 9 performs demodulation to listen the voice of the information through headphones, etc. |
