Abstract

PURPOSE:To eliminate the unnecessary queuing time by transmitting the necessary slave station selection signal and then transmitting the specified signal to start the aural circuit of the slave station selected by the selection signal. CONSTITUTION:The master station transmits the necessary slave station selection signals F1A, F1B...FnA, FnB after group selection signal, and then transmits specified signal FC (group selection signal FG available instead of FC) to start selected n-units of aural circuits (speaker driving amplifier). The selected station is kept under the queuing state until it receives signal FC. And also the voice is uttered for the first time when signal FC is received.
