An arrangement for the control and remote control of a battery driven apparatus is switched on and off upon the approach and withdrawal, respectively, of a user. The arrangement finds particular use in a water-rinsing system, which comprises an electrical adjustment member which can be activated upon the approach of the user. The apparatus transmits infrared detection pulses which are received again after reflection by the user. In response to the reflected pulses a control circuit (2) interrogates the measured charge state of the battery, conditions the adjustment member (7) to be switched on only if the battery (5) has a charge state such that the adjustment member can be switched off again, and transmits infrared state pulses instead of the detection pulses. The state pulses contain information about the charge state of the battery and can be received by an additional remotely located infrared reception unit (12) for evaluation.
