Abstract

PURPOSE:To secure display while simplifying the setting of signal synchronization, by decoding a tone for display information transfer sent after a selective calling signal and then by display a previously-fixed number, character, etc., corresponding to this tone. CONSTITUTION:A tone signal including a display signal and individual signal whose center frequency is varied by a control signal is allowed to pass through variable band-pass filter 30 and this signal is decoded by 1st decoder 50. A code from ROM70 is read out from its 1st digit in the previously-fixed order by this decoded start signal and then applied to 2nd decoder via control circuit 80 to set the center frequency of filter 30 by decoder 90 to a frequency corresponding to the input code, thereby setting a state where the tone signal can be received. Then, the tone signal is received continuously in sequence and a calling start signal corresponding to the reception contents is outputted from decoder 50 to actuate calling transfer unit 60; and further the start signal is sent to circuit 80, which controls 3rd decorder 100 to display them on display unit.
