The collar will memorize yourselected mode.Next time you will switch on the collar, your collar will be turned on to the last mode you previouslyselected.The chart below indicates how your collar operates according to the mode you have selected: Setting the barking detection sensitivityYour dog’s barking is detected by one of the contact points which sense the vibrations of his vocalcords (See Diagram 1).Setting the barking detection sensitivity is a very important preliminary operation. In fact, this settingdetermines the correct operation of the product.It ensures detection of any barking but helps avoid unnecessary detection. The detection musttherefore be sufficiently sensitive but not overly sensitive.In the factory, detection sensitivity is set on level 5 (medium sensitivity).To adapt the detection sensitivity to the barking strength of your dog, turn the button located on thefront of the collar according to the sensitivity you wish (See Diagram 1).Number of beep sounds togetherwith indicator light flashes emittedwhen switching modeMode Operation1 Nr 1 Beep sounds only2 Nr 2 Beep sound + light stimulation (sensitive dog)3 Nr 3 Beep sound + progressive stimulation4 Nr 4 Beep sound + strong stimulation (difficult dog)cel-B.indd 16 22/01/201
