hi mate point the locator down and the lights should be facing you make sure the locator is on and the other control is set on search some one hide the collar obviously within 16ft when you get to 8ft showing on search switch the button on to locate then it should take you right to it when you put the collar on the ferret make sure the unit on the collar is under the ferrets chin any problems let me know but make sure every time you start to look for your ferret the button should be set on search then to locate cheers lad DM
