Abstract
A testable pager including a receiver for demodulating a sequence of signals, and a manually operated switch. A controller receives the outputs of the receiver and the switch. The controller thereby switches on a power supply for the receiver for a set period after the start of the signal sequence. When the sequence includes a test code, the power supply stays on and a first test is performed. Actuations of the switch cause further tests to be made.
