Abstract

A two-way interactive addressable entertainment terminal comprises a processor, a keyboard, a character generator responsive to the processor and memory for storage of an algorithm related to the installation of the terminal and to providing a verification indication at the terminal of acknowledged entry of the terminal into an entertainment system. The character generator, responsive to the passage of a predetermined period of time since the application of power to the terminal, causes a number of screens to be displayed on an associated television receiver. The display screens reinforce the algorithm and provide indications of programmed key functions despite labels of keys on the keyboard. Consequently, a user or installer is capable of installing a terminal according to the present invention without any communication with personnel at the location of a system manager. By requiring the practically simultaneous occurrence of two events the application of power and the actuation of a predetermined key, inadvertent entry into either an installation mode or a maintenance mode of terminal operation is prevented.
