Abstract:
1. Method for protecting a commercial product against theft, in which a security unit has a monitoring mode in which theft protection is active such that a theft attempt will cause the security unit to switch to an alarm mode in which at least one of an acoustic and optical alarm is activated, the method comprising: deactivating, in the monitoring mode, a receiver housed in the security unit outside of the commercial product; and activating the receiver when the security unit is shifted to the alarm mode, wherein the security unit has an on-state mode in which the receiver is activated and wherein the security unit is shifted from the on-state mode to a connect mode in which theft protection is not active when the receiver receives a signal from the transmitter, wherein, in the connect mode, the security unit is prepared for a shift to the monitoring mode, and wherein the security unit is shifted from the connect mode to the alarm mode if the security unit is not prepared within a preset time interval for a shift to the monitoring mode.
