ABSTRACT A paging receiver comprises: a receiving section for receiving a carrier wave modulated with a calling signal including a first signal sequence and either a second or a third signal sequence which follows the first signal sequence, A power supply control supplies power to the receiving section in response to a first control signal. A controller section supplies the first control signal to the power supply control for a first predetermined time period in response to the detection of the first signal sequence so that the controller section can detect the second or third signal sequence, supplying the first control signal to the power supply control consecutively in order to shift the receiver to a first test mode when the third signal sequence is detected and shifting the receiver from the first test mode to a second test mode in response to a second control signal. A switch is connected to the controller section for generating the second control signal. The receiver can be tested for various adjustment and tests by inputting only one test code and manipulation of a reset switch. Further, a calling test can be conducted for measuring characteristics of the receiver with one same call number and the shortest code, thereby conveniently minimizing the time required for measurement.
