PROBLEM TO BE SOLVED: To provide an electronic unit which can effectively use the A/D port of a CPU. SOLUTION: A DC voltage which is outputted from an output detector 35 and which is for control at the time of transmission and a DC voltage which is outputted from an IFIC 43 and which is for control at the time of reception are inputted to the common A/D port 381 of the CPU 38. Transmission time (state where the DC voltage is supplied from the output detector 35 to the A/D port 381) and reception time (state where the DC voltage is supplied from the IFIC 43 to the A/D port 381) are discriminated by a PTT signal supplied to the input port 382 of the CPU 38. The CPU 38 controls transmission time by using the DC voltage from the output detector 35 at the time of transmission and controls reception time by using the DC voltage from the IFIC 43 at the time or reception.
