1. A portable radio communication device comprising:
- a radio section including a transmitting section and a receiving section, the transmitting section being configured to subject a to-be-transmitted signal to modulation to get a modulation-result signal and transmit the modulation-result signal, the receiving section being configured to receive an incoming signal and subject the received incoming signal to demodulation to get a demodulation-result signal;
a frequency operation section configured to vary at least one of a frequency used by the radio section for signal transmission and a frequency used by the radio section for signal reception when being operated;
a mute section configured to mute the outputting of the demodulation-result signal;
a mute cancel operation section configured to cancel the muting by the mute section when being operated;
a memory configured to store data sets assigned to respective memory channels, wherein each of the data sets includes frequency data representing at least one of a frequency used for signal transmission and a frequency used for signal reception, and letter data representing letters;
a display; and
a display control section configured to access the memory and control the display to indicate letters represented by letter data in a data set assigned to selected one of the memory channels when the mute cancel operation section is not operated to cancel the muting, and configured to access the memory and control the display to indicate at least one of a frequency for signal transmission and a frequency for signal reception which are represented by frequency data in the data set assigned to the selected one of the memory channels when the mute cancel operation section is operated to cancel the muting.

Abstract
A portable radio communication device includes a radio section using a frequency for at least one of signal reception and signal transmission. The frequency used by the radio section is set to a frequency assigned to a memory channel. A mute circuit mutes an audio output circuit when a mute-cancel or monitor switch is not operated, and unmutes the audio output circuit when the switch is operated. A display is controlled to indicate a name assigned to the memory channel when the switch is not operated, and to indicate the frequency assigned to the memory channel when the switch is operated.
