Pager receiver comprising a memory storing a sequence of information signals to be tested

摘要

In a pager receiver comprising a display circuit and an ROM, a controller produces a test mode signal indicative of a test mode in which either the display circuit or the ROM is tested. Responsive to the test mode signal, the ROM supplies the display circuit with a succession of display signals which are previously stored therein and representative of all alphanumeric symbols displayed by the display circuit, so as to test the display circuit. Alternatively, all of contents stored in the ROM are successively sent from the ROM to the display circuit in response to the test mode signal on testing the ROM, so as to inspect the contents. The test mode signal may be delivered from a transmitting end to the controller in the form of a radio calling signal or given to the controller by manual operation. The test mode signal may specify more than two sorts of tests.
