Arrangement Provided with a Recording Device
First Claim
1. An arrangement with a recording device comprising:
- a voltage source which supplies the recording device with power,a sensor which transmits a signal to the recording device on the basis of which the recording device stores recordings, wherein various modules of the recording device consume power and are designed so as to be capable of being switched off and on, and wherein the arrangement is operable in such a way that if there is a change in the operating voltage of the power supply a number of the modules are switched off or on.

Abstract
An arrangement (1) has a recording device, in particular a tachograph (2) for a motor vehicle, a voltage source (3) supplying power to the recording device and a sensor (S) transmitting a signal thereto, wherein different modules (7, 8, 9, MEM) of the recording device consume energy and are embodied in such away that they are connectable and disconnectable. In order to solve, in particular, a problem of a relatively unstable voltage supply, the aim of the invention is to design a system whose operation is low-affected by the voltage oscillations and interruptions and which is not overcharged by a just unstable energy supply. For this purpose, several (7, 8, 9, MEM) modules are disconnectable or connectable when the energy supply operating voltage (U) is modified.
