Abstract

PURPOSE: To enable mode display and level display to be performed with one display device through operation of changeover switches by using at least two of a plurality of light emitting diodes for mode display and the other as level meters.
CONSTITUTION: In the case of having transmission mode and reception mode as with a radio communication apparatus, closing the cooperating switches SW1 thru SW4 at the terminal a side sets the transmission mode, causing the voltage V from terminal 11 to be applied to a light emitting diode 12 through the switch SW4 and resistance R5. The diode then goes on to display the transmission mode. Light emitting diodes 13 thru 15 operate as level display devices which indicate percentage modulation according to the levels of the modulating wave signal applied to the terminal 1. Closing the switches SW1 thru SE4 at the terminal b side sets the reception mode, causing the light emitting diode 16 to go on and display the reception mode. In this case, the light emitting diodes 13 thru 15 operate as level display devices corresponding to the receiving signal levels having been spplied to terminal 17.
