<p><P>PROBLEM TO BE SOLVED: To provide a wireless device switching a signal scheme of a transmission radio wave without requiring complicated manipulations. <P>SOLUTION: When a carrier is received, if responding to the carrier, push-to-talk (PTT) is pressed. At such a time, if a transmission signal scheme of default setting is different from a reception signal scheme of a received audio signal, the transmission signal scheme is switched to the same signal scheme as the reception signal scheme, and the audio signal is then modulated. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
