Abstract

The invention relates to a method for transmitting and receiving according to which a transmitted signal is compared with a returned signal for function control. In case of a voltage drop below a predetermined value, at which the returned signal can no longer be reliably interpreted, signals to be transmitted are directly returned to the recipient.
