AVT739 A

Annoyer is used to make jokes to friendly people. After inserting the battery, the device should be hidden in the room where the victim will sleep. As long as it is bright, the system remains at rest. After extinguishing the light, it starts to produce short, annoying squeaks from time to time. These sounds have such a selected frequency and duration that it would be difficult to locate their source in the dark. When the 'object of harassment' lights up the light, the irritant stops. After an ineffective search the light is turned off (night after all) and the whole process is repeated.
AVT wishes you good luck both sides ;-)
