Proceeding to 50, it is determined whether the switch 33 is on. If the switch 33 is on, the power adapter is used, so that it is regarded as the home area. In step S60, the channel selection information at this time is stored in the preset channel of the first area of the nonvolatile memory 24 in ascending order of channel number, In step S70, an on-screen display of this preset channel is performed using a character generator. If the switch 33 is off, the power adapter is not used, so that the travel area is regarded as the travel area. In step S90, on-screen display of this preset channel is performed using the character generator 25.
After step S70 or S90, the process proceeds to step S20. If the selected frequency is equal to or higher than the highest frequency in step S30, the process ends.

If the switch 33 is on, the start address of the second area is set in the write address pointer. . Then, instead of steps S50 to S90, when the sync detection signal is supplied, the channel selection information is written to the address indicated by the write address pointer, and the value of the write address pointer is incremented by the number of words of one preset channel. Alternatively, the preset channel may be displayed on-screen and the process may proceed to step S20.

At 10, it is determined whether or not the switch 33 is on. If the switch 33 is turned on, the power adapter is used, so that it is regarded as the home area, and the preset channel in the first area of the nonvolatile memory 24 is displayed on-screen in step S120. On the other hand, if the switch 33 is off, the power supply adapter is not used, so that it is regarded as a travel area, and the preset channel in the second area of the nonvolatile memory 24 is displayed on-screen in step S130.

選局を行うことができ、手間を省くことができる。Next, when a preset channel displayed on the screen is selected from the operation unit 26 in step S140, the flow advances to step S150 to read channel selection information of the selected preset channel from the non-volatile memory 24 and read the selected channel information. And causes the tuning circuit 11 to tune to the preset channel, and terminates the processing. As described above, the switch 33 detects that the power adapter is inserted and connected to the adapter connection terminal 32 and determines whether the power adapter is the home area or the travel area. Since the preset channel is stored in the first area and is used in the travel destination when supplied with power from the battery 31, the preset channel is stored in the second area.
When returning to home from a travel destination, tuning can be performed without performing tuning scanning, and time and labor can be saved.

The switch 33 may be a manual switch for switching between a home mode and a travel mode in addition to the switch for detecting the insertion connection of the power adapter, or an adapter insertion detection switch and a manual switch may be provided side by side.
