Portable radio, and method for conveying information

A portable radio, comprising:

• transmit circuitry coupled to an antenna and to receive transmit channel information, wherein the transmit circuitry is configured to selectively transmit on one of a plurality of radio frequency channels dependent upon the transmit channel information;
• receive circuitry coupled to the antenna and to receive receive channel information, wherein the receive circuitry is configured to receive on one of the plurality of radio frequency channels dependent upon the receive channel information;
• tone generation circuitry configured to produce:
• a first sequence of audible tones in response to user input during initialization of the portable radio, wherein the first sequence of audible tones conveys the receive channel information;
• a second sequence of audible tones in response to user input during operation of the portable radio, wherein the second sequence of audible tones conveys transmit channel information indicative of a first transmit channel;
• channel selection circuitry coupled to receive the first and second sequences of audible tones from the tone detection circuitry, and wherein the channel selection circuitry is configured to:
• decode the first sequence of audible tones to produce the receive channel information, and to provide the receive channel information to the receive circuitry;
• and
• decode the second sequence of audible tones to produce transmit channel information indicative of a first transmit channel, and to provide the transmit channel information indicative of the first transmit channel to the transmit circuitry as the transmit channel information.
