The use of the vibration followed by increasingly intense shocks sets up a pattern that your dog will quickly learn is caused by its own barking. It takes time to break bad habits. ON-OFF & Intensity Dial:This dial is to turn the device on/off and select the intensity level of stimulation;'OFF' position is to turn off the device;Level 'V'---The device will vibrate only;Level 2 is the lowest electrical stimulation and level 5 is the highest;From Level 2~Level 5, the device will all vibrate first and then follow by static shock. Sensitivity Dial:This sensitivity dial is to adjust the sensitvity to the dog bark according to the environments the dog is in, level 'T' is the most sensitivity and level 1 is the weakest, when testing the device, set it to the level 'T'. Testing:1. Turn the device on by turning OFF & Intensity dial and set to 'V' mode;2. Set the sensitivity dial to 'T' level;3. Test by scratching the rough surface of the test tool on the device(as you seen in the manual) using a fingernail or pen. The device will emit a vibration for 1.5 seconds. Then repeat the same process if you want to try it again. NOTE:1. When the no bark collar emits a vibration, a stimulation is not emitted at the same time;2. When you set the dial on the test level, it may be sensitive enough that the no bark collar can be actived easily by small sound or tap; Accessories:1 x Bark Terminator1 x Adjustable nylon belt1 x Plug1 x Charging Cable1 x Test Light4 x Metal Probes1 x Operating Guide Packing:CTN MEAS44*34*34cmQty/CTN46 pcsN.W11.5 kgG.W13 kg
