ABSTRACT:
A method for recording information that is transmitted over a radio frequency, especially traffic information, in which, in a monitoring state, the receiving device is supplied with power in a clocked manner. While switched on, the receiving device is tuned to a preestablished radio frequency and the received radio frequency is monitored for the presence of an identifier designating information. In the event an information identifier is detected, the receiver is supplied with power for the duration of the identifier and the information is recorded. In response to switching on the monitoring state, the preestablished radio frequency is determined as the frequency to which a radio frequency refers that transmits no information and that was set before the monitoring state was switched on.
