Abstract
A remote control is provided for controlling various electronic apparatus such as televisions, videocassette recorders, stereo systems, cable boxes, and the like. The remote control includes a loop-back, self-test capability, which indicates the operability of the remote control without additional testing apparatus. Status of the self-test, and thus the remote control, is indicated to the user by an audio/visual status indicator located on the remote control. The remote control optionally includes two infrared diodes to transmit a self-test signal with a reduction in directionality limitations.
