Abstract
A remote control system has a transmitter, a current storage device feeding its triggerable control signals, an external receptacle into which the transmitter can be inserted, and a charge monitoring device with charge-state indicator. The charge monitoring device with charge-state indicator is assigned to the receptacle and preferably causes the transmitter to automatically transmit a control signal after being inserted into the receptacle. Via the charge monitoring device, the charge state of the transmitter can be evaluated independently of the voltage supply from the current storage device of the transmitter either directly via its voltage supplied under load or indirectly via the intensity of the control signal emitted by it, and be indicated if respective minimum values are undershot. The system is suitable for remotely controlling motor-vehicle security devices.
