A remote control (10) is provided for controlling various electronic apparatus such as televisions, videocassette recorders, stereo systems, cable boxes, and the like. The remote control (10) includes a loop-back, self-test capability, which indicates the operability of the remote control (10) without additional testing apparatus. Status of the self-test, and thus the remote control (10), is indicated to the user by an audio/visual status indicator located on the remote control (10). The remote control (10) optionally includes two infrared diodes (18) to transmit a self-test signal with a reduction in directionality limitations. |
