Further, in this state, if there is no reception signal in the radio communication unit 3 and the operation key of the radio communication unit 3 is not operated for three seconds, the radio reception unit previously set again Return to (Display on display and radio signal output).

In the embodiment of the present invention, when the power switch of the main body is turned on, the communication mode at the end of the previous time (or the wireless communication only mode when initialized) is started. The next # 1 to # 3
Operation mode is repeated. (# 1: wireless communication only mode) The communication (signal transmission and reception) function operates at the frequency set as the wireless communication.
The power supply to the radio receiving unit is stopped and there is a power saving effect. (# 2: Radio reception only mode; (ABC OF)
F) Auto band change off) Power is supplied to the radio receiver and only the radio operates. The power supply to the wireless communication unit is stopped and the power is saved (# 3: radio reception mode; (ABCON) auto band change on). The power is supplied to the respective sections, and each of them enters a receiving state under a preset condition. In this state, first, the signal of the radio receiving unit is output to the audio amplification circuit that amplifies the audio signal.

Next, when the radio communication unit 3 receives a signal at the set frequency, for example, the means for detecting a carrier wave
When it is determined that the carrier wave level is equal to or higher than a preset level, a signal for switching an audio signal switching switch is output.
In response to this, the audio signal switching unit 7 turns off the output of the radio reception unit 2 and turns on the reception signal of the wireless communication unit 3 to output to the audio signal amplification circuit 8 which amplifies the audio signal.

Here, when the power is turned off, the set state immediately before the power is turned off is stored. When the power switch is turned on, the same wireless mode as when the power is turned off is set.

Next, the operation procedure of the wireless communication apparatus according to the present embodiment will be described with reference to the flowchart of FIG.

After the operation of the apparatus is started, PLL data on the radio side and FM radio side are output, the set FM radio is received (step S1), and a frequency reception check on the radio side is executed (step S2). It is determined whether or not the radio frequency has been received (steps S3, S4). If it has not been received, the process returns to step S2, and if it has been received, it is determined whether or not the group function is ON (steps S5 and S6). At this time, if it is ON, it is determined whether or not the group numbers match (steps S8 and S9), and if they do not match, the process returns to step S2.

If it is determined in step S5 that the signal is OFF, or if it is determined in step S9 that there is a match, in step S7, the display or operation is shifted to the wireless device (step S7), and the received signal of the wireless device is Not
It is determined whether three seconds have elapsed without any key operation (steps S10 and S11). If it is determined that three seconds have not elapsed, the process returns to step S10, and it is determined that three seconds have elapsed. Returns to the FM radio broadcast again, receives the above frequency (step S12), and ends the processing.
