Abstract: This invention enables a user to locate a missing remote control unit for an appliance, such as a television set, by causing the missing unit to emit an alarm. The television set includes a transmitter which is controlled by a switch mounted on the television cabinet. The remote control unit includes a receiver, capable of detecting a signal from the transmitter. The receiver activates an alarm, which can be audible, visible, or both. When the switch is depressed, and if the remote control unit is within range, the alarm will be activated, and the unit is easily located. The transmitter can be controlled by a timer which governs the period during which the alarm sounds. Also, the transmitter can be connected to a lamp, or other indicator, to show the user when the transmitter is operating. The transmitter and switch can be built into the television cabinet, or they can be housed in a separate unit which is attached to the cabinet.
