Then, the control part, based on matching information of a storage part, confirms whether the caller information matched with the extracted caller phone number exists(240). In case the caller information matched with the extracted caller phone number exists, the control part extracts the matched caller information and converts it into a caller information signal by using a text conversion part(250). Then, the control part converts the converted caller information into a call information voice through a codec and outputs it through an ear-microphone(260).

Abstract: An apparatus includes a reception circuit (33) with a frequency synthesizer, a decoder (32) for digitally demodulating an audio file signal from the reception circuit, and a processor (34) for initializing the decoder (32) in response to a loss of a phase lock in the demodulating of the audio file signal and setting the frequency synthesizer at one of a plurality of frequencies to re- establish the phase lock in the demodulating of the audio file signal. The plurality of frequencies are 900MHz range channel frequencies. Preferably, the plurality of frequencies are 905 MHz, 911 MHz, 917 MHz and 923 MHz. The decoder includes an eight-to-four modulation EFM digital decoder. Demodulating the audio file signal provides a digital audio stream conforming to an I2S audio format. The processor is preferably a microprocessor (34).
