PURPOSE: To enable the transfer of an abbreviated dial number by using a prescribed software. CONSTITUTION: When a frequency synthesizer 103 locks a channel to an optional one under the control of a microprocessor 110, a receiver 102 measures electric field intensity. This is executed for all the channels to be scanned so as to obtain the channel of the most intense electric field. At this time a user selects a mode (an abbreviated dial number batch transfer mode, an abbreviated dial number partial transfer mode, etc.) in software so as to send a command corresponding to it by the combination of DTMF(dual tone multifrequency) signals prescrived in advance. As the result of this, transfer from a master radio telephone set is facilitated even when the transfer is executed between radio telephone sets which are physically distant from each other. |
